Introduction: Phosphorus (P) is a crucial growth-limiting nutrient in soil, much of which remains challenging for plants to absorb and use. Unlike chemical phosphate fertilizers, phosphate-solubilizing microorganisms (PSMs) offer a means to address available phosphorus deficiency without causing environmental harm. PSMs possess multiple mechanisms for phosphorus solubilization.

Polylactic acid (PLA) microplastics (MPs) and lead (Pb) co-contamination, an emerging co-contamination, may profoundly impact plant growth. We aimed to evaluate the effects of PLA-MPs and Pb on buckwheat growth and physiology and to elucidate the underlying molecular mechanisms through an integrated transcriptomic and metabolomic approach. PLA-MPs alone reduced buckwheat biomass by 26.

Here, thermophilic bacteria (TB) with cellulose degradation functions were screened from composting panda feces and applied to cattle manure composting. TB (Aeribacillus pallidus G5 and Parageobacillus toebii G12) inoculation led to remarkable improvement of the compost temperature, prolonging of the thermophilic stage and shortening of the composting process, resulting in increased manure harmlessness (GI ≥ 70%), compost humification, and greenhouse gas emission reduction (14.19%-22.

Cadmium contamination poses a significant risk to soil ecosystems in certain parts of the world. Using eco-friendly fertilizers alongside beneficial microorganisms offers a viable solution to mitigate Cd pollution in agricultural soil. This study used an outdoor experiment to evaluate the impact of administering a Cd-immobilizing bacterial (Bacillus) inoculant with two biologically-enriched organic fertilizers (either fermentative edible fungi residue or fermented cow dung) on wheat plants and associated microbial populations in a field contaminated with Cd.

Soil pollution by microplastics (MPs), defined as plastic particles <5 mm, and heavy metals is a significant environmental issue. However, studies on the co-contamination effects of MPs and heavy metals on buckwheat rhizosphere microorganisms, especially on the arbuscular mycorrhizal fungi (AMF) community, are limited. We introduced low (0.

The process of carbohydrate metabolism and genetic information transfer is an important part of the study on the effects of the external environment on microbial growth and development. As one of the most significant environmental parameters, pH has an important effect on mycelial growth. In this study, the effects of environmental pH on the growth and nutrient composition of () filaments were determined.

With continuous mine exploitation, regional ecosystems have been damaged, resulting in a decline in the carbon sink capacity of mining areas. There is a global shortage of effective soil ecological restoration techniques for mining areas, especially for vanadium (V) and titanium (Ti) magnetite tailings, and the impact of phytoremediation techniques on the soil carbon cycle remains unclear. Therefore, this study aimed to explore the effects of long-term Pongamia pinnata remediation on soil organic carbon transformation of V-Ti magnetite tailing to reveal the bacterial community driving mechanism.

Seemingly barren heavy-metal-polluted vanadium (V) and titanium (Ti) magnetite mine tailings contain various functional microbes, yet it is unclear whether this includes microbial resources relevant to the biological control of plant diseases. Kiwifruit brown leaf spot disease, caused by , can seriously reduce kiwifruit yield. To discover effective control measures for kiwifruit leaf spot, 18 bacteria strains among 136 tailing-isolated bacteria from V-Ti magnetite mine tailings were identified as inhibiting by the confrontation plate method, indicating that antagonistic bacteria surviving in the V-Ti magnetite mine tailings were present at a low level.

Systemic acquired resistance (SAR) is an inducible disease resistance phenomenon in plant species, providing plants with broad-spectrum resistance to secondary pathogen infections beyond the initial infection site. In , SAR can be triggered by direct pathogen infection or treatment with the phytohormone salicylic acid (SA), as well as its analogues 2,6-dichloroisonicotinic acid (INA) and benzothiadiazole (BTH). The SA receptor non-expressor of pathogenesis-related protein gene 1 (NPR1) protein serves as a key regulator in controlling SAR signaling transduction.

Heavy metal and antibiotic-resistant bacteria from livestock feces are ecological and public health problems. However, the distribution and relationships of antibiotic resistance genes (ARGs), heavy metal resistance genes (HMRGs), and virulence factors (VFs) and their transmission mechanisms remain unclear. Therefore, we investigated the resistance of Escherichia coli, the prevalence of its ARGs, HMRGs, and VFs, and their transmission mechanisms in livestock fresh feces (FF), composted feces (CF), and fertilized soil (FS).

Brown film formation, a unique developmental stage in the life cycle of , is essential for the subsequent development of fruiting bodies in cultivation. The pH of mushroom growth substrates are usually adjusted with hydrated lime, yet the effects of hydrated lime on cultivating and the molecular mechanisms associated with the effects have not been studied systemically. We cultivated on substrates supplemented with 0% (CK), 1% (T1), 3% (T2), and 5% (T3) hydrated lime (Ca (OH)), and applied transcriptomics and qRT-PCR to study gene expression on the brown film formation stage.

In industrial production, the excessive discharge of furfural can pose harm to soil microorganisms, aquatic animals and plants, as well as humans. Therefore, it is crucial to develop efficient and cost-effective methods for degrading furfural in the environment. Currently, the use of Saccharomyces cerevisiae for furfural degradation in water has shown effectiveness, but there is a need to explore improved efficiency and tolerance in S.
