Not with its own roots, at least. Beyond the roots of the plant itself, a network of fungi expands and brings from the deepest parts of the soil all of the necessary nutrients for the plant’s tasks of producing food and sustaining itself. This type of fungi is called mycorrhizal fungi, from the Greek words ‘mýkes’ and ‘rhiza’; ‘fungus’ and ‘root’ respectively, and these mycorrhizal fungi and plants maintain a mutualistic relationship that goes back millions of years. A symbiotic association between mycorrhiza fungi liquid and plants is established at the root level. To allow two-way nutrition exchange, these mycorrhiza liquids envelop and, in some cases, penetrate the structure of plant roots. Arbuscular mycorrhizal fungi use their mycelium to expand the roots of the plants they interact with, making it easier for them to obtain nutrients, minerals, and water from a greater distance. Photosynthesized sugars are given to the fungus by the mycorrhizal plant in exchange. Some arbuscular mycorrhizal fungi examples are ectomycorrhiza (the fungi responsible for a lot of the mushrooms that can be found in a forest), orchid mycorrhiza (those help orchids and similar plants obtain nutrients from the air), and arbuscular mycorrhiza. Arbuscular mycorrhizal is the most widespread type, occurring in over 85% of all plant families and throughout most crop species. What are the benefits of mycorrhizal associations? Extending the reach of the plant’s roots (often doubling and triplicating them, under favorable conditions) thus increasing not only the depth they can reach but also the amount of surface covered by root mass. Stimulating the absorption of all important nutrients (nitrogen, potassium, iron, manganese, magnesium, copper, zinc, boron, sulphur and molybdenum) by enhancing their availability. Particularly improving the rate of uptake and mobilization of phosphate across all crops, thus reducing phosphorus fertilization requirements. Outcompeting harmful pathogens by rapidly colonizing the roots of the plants, creating a protective barrier against root diseases. Mycorrhizal soil is much harder for pests to colonize, simply because there’s no space for them. Generating an immune response in the plant that, while not killing mycorrhizal fungi, increases the resistance of the plant to future fungal diseases, thus serving as something akin to a ‘plant vaccine’. Producing chemical compounds that attract pest predators when a plant is under attack by pests, mirroring the processes that the plant uses to produce such compounds and boosting predator attraction. Dramatically increasing plant resistance to changing climate and soil conditions such as drought, heat, and even salinity increase. Water absorption, in particular, is enhanced by the mycelia of mycorrhizal fungi serving as root hairs for this purpose. Increasing the overall yield of your plants, by the combined functions of improved nutrient and water absorption and increased resistance to disease and climate conditions. Reducing soil erosion through the production of glomalin by the mycorrhizal fungi, which serves as a binding agent that improves soil structure and increases carbon content. When applied to soil mycorrhizal fungi will produce this protein to coat their hyphae, beneficially releasing it into the ground when they die. A case in practice: mycorrhizal inoculation in corn crops For a simple answer to the question of what are mycorrhizal fungi (and, above all, why do they matter), in the image at left it is possible to see a graphic depiction of how well corn responds to a mycorrhizal fungi inoculation. Arbuscular mycorrhizal fungi grow from within the cells of the roots themselves, serving as ‘branches’ for the expansion of the root system. The fungi associate themselves with the cellular structure of the roots, and begin expanding their hyphae through the soil, bringing nutrients and water to the plant and increasing their reach as their plant host grows stronger and larger. This increases the efficiency with which the plant absorbs the nutrients present in the soil, reducing nutrient runoff and fertilization requirements, as well as improving resistance to drought and disease; ultimately increasing yields and overall plant health. Methods of application of mycorrhizal fungi: The following table provides a basis for how to use arbuscular mycorrhizal fungi in different scenarios, detailing, in particular, the doses required according to each method and to the type of plant being grown (annuals vs. perennials): 1. Application by seed dressing: In an appropriate container for the volume of product required, mix the mycorrhizal inoculant with crude sugar at a proportion of two parts of sugar for one part of mycorrhizal inoculant (for 20-100 kilograms of seed, 100 grams of sugar per 50 grams of mycorrhizal inoculant) insufficient water to make a slurry. Use this liquid preparation to coat the seeds, and allow them to dry in the shade before sowing, casting or dibbling them in the field. Do not store the coated seeds for more than 24 hours before planting. 2. Application directly into soil: Mycorrhizal fungi can be directly applied into the soil through several different strategies, detailed next. Mix the mycorrhizal inoculant with compost at the required dosages, and apply this mixture directly into the soil at the early life stages of the plants, along with any other biofertilizers that may be used. Mix the mycorrhizal inoculant with water at the required dosages, and apply this mixture directly into the soil at the early life stages of the plants, along with any other biofertilizers that may be used. Apply the mycorrhizal inoculant mixed with water under a drip irrigation scheme, filtering out the solution before adding it to the drip tank if any insoluble particles are noticed during its preparation. Use mycorrhizal fungi to boost the continued growth of perennial plants by dissolving the mycorrhizal inoculant in water at the adequate dosage, and drenching the soil where the roots are (for trees, use the drip line as a reference) twice a year. It is recommended to make a first application of this mixture before the onset of the spring, rainfall season or first monsoon, and the second application after the end of the main monsoon, rainfall season or spring season. 3. Application of mycorrhizal fungi as spray. It is recommended that mycorrhizal fungi are applied as close as possible to the roots they will colonize, to ensure maximum effectivity and inoculation rate. If applying as a spray, mix the mycorrhizal liquid at a proportion of 5 milliliters per liter of water, and spray at the drip line of the canopy of the plant. The total volume of the mycorrhizal mixture required may vary depending on the canopy size (and its corresponding drip line).

Modern molecular biology and field-scale studies have validated its benefits for crop nutrition, environmental sustainability, and cost-effectiveness. The bacterium’s versatility and resilience are supported by its diverse regulatory, metabolic, and stress response mechanisms, which make it compatible across a wide range of soil conditions and crop systems. Laboratory Contaminant Significance Paenibacillus species are widely distributed in natural and built environments, including soil, water, and air. Their ability to form spores and survive harsh conditions means they are frequent laboratory contaminants. In clinical and research laboratories, Paenibacillus can be isolated from surfaces, air, gloves, and sample materials—often as part of sterility testing. Several species, including Paenibacillus contaminans, have been specifically described as contaminants during laboratory plate handling. This is particularly relevant in low-biomass environments, as modern sequencing or culture approaches can easily detect spores or cells introduced during sample processing or from ambient air. The high occurrence of Paenibacillus as a contaminant can result in false-positive results, especially in blood cultures, sterile fluids, or low-biomass samples. Proper sample collection, rigorous sterilization, and careful interpretation of culture results are imperative. Contaminants are often identified retrospectively by phylogenetic and phenotypic analysis and may comprise the majority of positive cultures unless clear clinical evidence of infection is present. pmc.ncbi.nlm.nih+3 Human Pathogenicity Paenibacillus species are generally regarded as environmental and plant-associated bacteria. However, accumulating evidence shows that a subset can act as opportunistic pathogens in humans—particularly in immunocompromised individuals, neonates, or following traumatic injuries. Human infections are rare but increasingly described in clinical case reports and systematic reviews. Several species implicated in human disease include P. alvei, P. thiaminolyticus, P. lautus, P. provencensis, and others. Infections range from wound infections, abscesses, ocular infections, sepsis, meningitis, and, rarely, endocarditis. Pathogenicity is driven by several factors: Spore formation and environmental resilience: Spores remain viable on skin surfaces and within hospital environments, making transmission and infection possible under specific conditions. d-nb+1 Virulence factors: Some Paenibacillus possess genes for thiol-activated cytolysins, proteases, biofilm formation, and antimicrobial compound production. journals.plos+3 Antibiotic resistance: Many isolates demonstrate resistance to multiple antibiotics, particularly penicillins, clindamycin, sulfonamides, and sometimes vancomycin, calling for careful susceptibility testing. pure.psu+4 Clinical Management Recommendations Management of Paenibacillus infections hinges on accurate diagnosis and effective antimicrobial therapy. As precaution, clinicians should: Differentiate true infection from contamination: Always correlate positive cultures with clinical signs (fever, leukocytosis, infection at the site), especially when Paenibacillus is isolated from blood, sterile fluids, or deep wounds. pmc.ncbi.nlm.nih+2 Empiric and directed antibiotic therapy: Initial therapy is empiric, but due to variable resistance patterns, therapy should be adjusted based on susceptibility testing. Effective options typically include cefotaxime, ceftriaxone, gentamicin, amikacin, rifampicin, metronidazole, and levofloxacin, while resistance to penicillins, clindamycin, and vancomycin can occur. Trimethoprim-sulfamethoxazole may be used for P. urinalis. droracle+6 Remove or drain infection sources: Surgical removal of infected tissues, foreign bodies, or abscess drainage may be necessary in localized infections. Monitor for complications: Especially in infants, Paenibacillus can cause severe complications like meningitis and hydrocephalus, requiring close monitoring and sometimes neurosurgical intervention. thelancet+2 Follow-up and continuity of care: Persistent infections require long-term medical follow-up and sometimes prolonged antibiotic administration. pmc.ncbi.nlm.nih+1 Current Knowledge of Human Infections Systematic reviews and case series demonstrate that although Paenibacillus species are uncommon human pathogens, the number of species associated with clinical infections is growing. Infection presentations differ notably between adults and infants: Adults: Infections are sporadic, caused by a wide array of species, often present as wound infections, abscesses, or localized sepsis. Central nervous system involvement is rare, and most cases resolve with treatment. pubmed.ncbi.nlm.nih+2 Infants: Neonatal infections are far more severe, especially with P. thiaminolyticus, and often present as sepsis or meningitis with a high risk of cerebral destruction and hydrocephalus. Mortality rates are notable, and survivors often need surgical intervention for neurological sequelae. pmc.ncbi.nlm.nih+3 The overall frequency of infection remains low relative to the ubiquity of the genus, indicating that most isolates are contaminants, but vigilance is still warranted for at-risk populations.

Answer: Paenibacillus species are among the most frequently isolated laboratory contaminants, especially in low-biomass and sterile sample environments. Their spores persist in air, on surfaces, and even on personal protective equipment, leading to inadvertent contamination of cultures and clinical specimens. Laboratory contaminants can cause diagnostic confusion, particularly when isolated from blood cultures or sterile sites, given the genus’s environmental prevalence. Recognizing Paenibacillus as a contaminant is vital to prevent misdiagnosis, unnecessary antimicrobial therapy, and misleading research conclusions. Rigorous sample handling and critical assessment of laboratory results are essential in distinguishing contamination from true infection. sciencedirect+4 Can Paenibacillus species exhibit pathogenicity in humans? Answer: Although primarily environmental and plant-associated, certain Paenibacillus species can exhibit pathogenicity in humans, particularly in vulnerable populations such as neonates, immunocompromised individuals, or following trauma. Documented infections include sepsis, wound infection, abscesses, meningitis, endocarditis, ocular infections, and rare systemic disease. Species like P. alvei, P. thiaminolyticus, and P. lautus are increasingly identified as clinical pathogens. In neonates, P. thiaminolyticus is notably associated with severe CNS infections. Virulence factors, antibiotic resistance, and spore persistence contribute to pathogenic potential, although true infections remain rare compared to environmental contamination. wwwnc.cdc+9 What are the recommended clinical approaches for managing Paenibacillus infections? Answer: Management is guided by accurate diagnosis and susceptibility-directed antimicrobial therapy. Clinicians should distinguish true infection from laboratory contamination, correlate culture results with clinical findings, and employ targeted treatment. Empiric therapy can include cefotaxime, ceftriaxone, gentamicin, amikacin, levofloxacin, and rifampicin, but resistance to penicillin, clindamycin, vancomycin, and sulfonamides is not uncommon. Susceptibility testing is imperative prior to finalizing antibiotic choice. Additional interventions such as surgical drainage of infected tissues may be necessary. Neonatal and CNS infections require close multidisciplinary management. Long-term monitoring is advised due to the potential for persistent or recurrent infection and post-infectious complications. pmc.ncbi.nlm.nih+7 What is currently known about human infections caused by Paenibacillus species? Answer: Human Paenibacillus infections, while uncommon, are increasingly recognized in pediatric and adult populations. Infections in adults are sporadic and generally mild, presenting as localized wound infection, abscesses, or sepsis, and most affected individuals recover without severe sequelae. Neonatal infections, especially those due to P. thiaminolyticus, are severe and often complicated by brain injury, hydrocephalus, and require surgical intervention, with notable associated mortality. The rise in documented cases reflects improved detection, growing awareness, and advances in microbiological diagnostics. Nonetheless, the majority of clinical isolates are contaminants rather than true pathogens, highlighting the importance of careful clinical interpretation and management. Ongoing research is elucidating new species, virulence mechanisms, and optimized treatment protocols. sciencedirect+9 Sustainability Advantage Related Products Acetobacter xylinum Azospirillum brasilense Azospirillum lipoferum Azospirillum spp. Azotobacter vinelandii Beijerinckia indica Bradyrhizobium elkanii Bradyrhizobium japonicum More Products Resources Read all

Sulfur Oxidation Pathway Primary Biochemical Mechanism: Acidithiobacillus thiooxidans employs a multi-enzyme network to oxidize reduced inorganic sulfur compounds (RISCs) into sulfate. Elemental Sulfur Oxidation: Initiation enzyme: Sulfur dioxygenase (SDO; EC 1.13.11.18) Reaction: 2S⁰ + 3O₂ + 2H₂O → 2H₂SO₄ Rate: 2-8 mg S/g dry biomass/day (soil conditions); up to 100 mg/L in culture pH change: Gradual reduction from neutral to acidic conditions Intermediate Sulfur Oxidation: Thiosulfate oxidation: Involves thiosulfate dehydrogenase and tetrathionate intermediate formation Polysulfide oxidation: Direct oxidation of polysulfide chains Sulfite oxidation: Complete oxidation via sulfite oxidase enzymes Energy Generation: The oxidation reactions serve as the exclusive energy source for A. thiooxidans, powering ATP production through electron transport chain mechanisms: Electrons derived from S⁰ oxidation flow through cytochrome complexes Oxidative phosphorylation generates ATP for biosynthetic processes CO₂ fixation via the Calvin cycle provides organic carbon from atmospheric CO₂ 2. Acidification Mechanism Sulfuric Acid Production: The complete oxidation of elemental sulfur to sulfate produces sulfuric acid, which dissociates in soil solution: H₂SO₄ → 2H⁺ + SO₄²⁻ pH reduction: Typically 7.0-8.0 (alkaline) → 5.5-6.5 (slightly acidic) Localized vs. bulk: Bacterial aggregation creates micro-acidic environments around sulfur particles Controlled Acidification Advantage: Unlike rapid chemical acidification (e.g., adding mineral acids), biological sulfur oxidation provides: Gradual pH change preventing root damage Localized acid production concentrated around sulfur particles Sustained effect throughout growing season pH regulation prevents over-acidification through buffering interactions with soil minerals Soil Buffering and Sustainability: The acidification process continues as long as elemental sulfur particles remain available and moisture and oxygen conditions are adequate. In alkaline soils, acid production is partially neutralized by carbonate reactions: CaCO₃ + H₂SO₄ → CaSO₄ + H₂O + CO₂ Net effect: Sustained pH reduction despite buffering capacity 3. Nutrient Mobilization Mechanisms Primary and Secondary Micronutrient Release: Iron Mobilization: Lowered soil pH converts insoluble ferric hydroxide (Fe(OH)₃) to soluble ferrous iron (Fe²⁺) Ferrous iron is readily absorbed by plant roots and transported through vascular tissues pH-dependent availability: Each 1.0 pH unit decrease increases Fe availability 10-100 fold Zinc Mobilization: Zinc silicates and oxides become soluble at pH <7.0 Complexation with organic acids (produced during sulfur oxidation) further enhances Zn bioavailability 25-40% increase in Zn concentration in soil solution Manganese and Copper Mobilization: Similar pH-dependent solubility increases Chelation effects from organic acids enhance bioavailability 20-35% increase in plant-available micronutrients Phosphorus Availability: Improved soil pH reduces phosphate fixation by iron and aluminum oxides Secondary effect improving overall nutrient balance 4. Biofilm Formation and Rhizosphere Colonization Biofilm Architecture: A. thiooxidans forms biofilms on elemental sulfur particles and soil mineral surfaces, enhancing sulfur oxidation efficiency: Extracellular polymeric substances (EPS): Polysaccharides and proteins trap water and nutrients Cell aggregation: Biofilms can reach 10⁸-10⁹ CFU per gram of biofilm Oxygen gradient management: Biofilm structure enables anaerobic bacterial zones with access to oxygen at biofilm surface Nutrient concentration: Localized nutrient accumulation in biofilm matrix Rhizosphere Persistence: Colonization density: 10⁶-10⁸ CFU per gram of rhizosphere soil Persistence period: 8-16 weeks under favorable conditions; periodic re-inoculation recommended for sustained benefit Root surface colonization: Bacteria attach to root epidermis; hyphal invasion not observed (non-pathogenic) 5.

Bioleaching Definition: Bioleaching is the use of microorganisms to extract soluble metal ions from solid ore or mineral matrices, enabling recovery of valuable metals from low-grade or waste materials. Thiobacillus thiooxidans Role in Bioleaching: 1. Sulfide Mineral Oxidation: The bacterium oxidizes reduced sulfur in sulfide minerals (pyrite, chalcopyrite, sphalerite, etc.): Reaction: FeS₂ + 3.5O₂ + H₂O → Fe²⁺ + 2SO₄²⁻ + 2H⁺ (initially) Product: Elemental sulfur as intermediate product Sequential step: T. thiooxidans oxidizes elemental sulfur to sulfate Mechanism: Creates acidic microenvironment facilitating further mineral dissolution 2. Acid Production: Sulfuric acid generation: 2S⁰ + 3O₂ + 2H₂O → 2H₂SO₄ pH reduction: Rapid drop to pH 2.0-3.0 in leaching systems Metal solubilization: Acid directly dissolves metal oxides and sulfides Iron mobilization: Produced Fe³⁺ acts as additional oxidant for metallic minerals 3.
