Published: Dec. 13, 2023

Abstract Bacillus sp. MEP 2 18, a soil bacterium with high potential as source of bioactive molecules, produces mostly C16–C17 fengycin and other cyclic lipopeptides (CLP) when growing under previously optimized culture conditions. This work addressed the elucidation genome sequence 18 its taxonomic classification. The comprises 3,944,892 bp, total 3474 coding sequences G + C content 46.59%. Our phylogenetic analysis to determine position demonstrated that assignment strain velezensis species provides insights into evolutionary context functional attributes. in silico revealed eleven gene clusters involved synthesis secondary metabolites, including non-ribosomal CLP (fengycins surfactin), polyketides, terpenes, bacteriocins. Furthermore, genes encoding phytase, release phytic phosphate for plant animal nutrition, or enzymes such cellulase, xylanase, alpha 1–4 glucanase were detected. In vitro antagonistic assays against Salmonella typhimurium , Acinetobacter baumanii Escherichia coli among others, broad spectrum produced by 18. expanded our understanding diversity genetic relationships within genus updated databases unique trait produce antibacterial fengycins resource biotechnologically useful enzymes.

High ectomycorrhizal relative abundance during winter at the treeline

ISME Communications, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 25, 2025

Abstract The rhizosphere is the soil region around plant roots hosting a diverse microbial community, influencing nutrient availability and how plants react to extreme conditions. However, our understanding of fungi biodiversity impact environmental variations on this still in its infancy. Our study investigates fungal communities’ diversity functional traits Nothofagus pumilio, one few winters deciduous treeline species world, forming southern South America. At four distinct locations covering 10° latitude, we collected samples at 200 meters below over seasons during single year. We employed ITS metabarcoding elucidate community structures. results reveal that was mainly determined by latitudinal variation, with higher levels warmer lower altitudes. Interestingly, found marked dominance ectomycorrhizal (EcM) treeline, particularly winter. In contrast, saprotrophic were more abundant altitudes, spring summer seasons. These findings highlight temporal spatial dynamics rhizospheric communities their potential roles ecological processes, emphasizing value these as indicators change high-elevation forests.

Microbial Communities in Permafrost, Moraine and Deschampsia antarctica Rhizosphere Soils near Ecology Glacier (King George Island, Maritime Antarctic)

Diversity, Journal Year: 2025, Volume and Issue: 17(2), P. 86 - 86

Published: Jan. 25, 2025

While the recession of glaciers in Antarctic is global concern under climate change, impact deglaciation on soil microbiomes still limited. Here, samples were collected from permafrost (P), moraine (M) and Deschampsia antarctica rhizosphere (R) soils near Ecology Glacier (Antarctic), their physicochemical properties microbial communities (bacteria, archaea fungi) characterized. Our analyses showed that there significant differences between R P M samples. Specifically, amplicon sequencing 16S rDNA revealed high bacterial richness diversity studied soils, which dominated mainly by phyla Proteobacteria, Actinobacteriota Bacteroidota. In contrast, lower observed archaeal communities, Chenarchaeota (M R) Thermoplasmadota (M). addition, fungal community analysis a R), phylum Ascomycota. observations are consistent with previous reports describing relevant changes during glacial recession, including fewer groups (archaea fungi). However, further studies needed to elucidate contributions formation plant colonization ice-free Antarctica change.

Published: March 3, 2025

Biocontrol has emerged as an effective strategy for managing plant pathogens and pests. The use of growth-promoting rhizobacteria (PGPR) biocontrol agents offers a sustainable alternative, enhancing morphology, biochemistry, physiology, secondary metabolism. This study conducts bibliometric analysis systematic review PGPR-based research from 2019 to 2023, using the Web Science (WoS) database. A total 2823 publications were identified, with significant increase in scientific output since 2019. Original articles dominated field, India, China, USA, Pakistan leading publication volume. Key contributors included Babalola (North-West University, South Africa), Kloepper (Auburn USA), Shen (Nanjing Agricultural China), each at least 25 publications. Co-authorship revealed four major networks centered Brazil, Canada. Bacillus Pseudomonas most studied PGPR genera, recognized their roles bioinoculants, bioremediators, biostimulants, mitigating negative impacts synthetic fertilizers pesticides. underscores growing global focus on its potential agriculture.

Agronomy, Journal Year: 2025, Volume and Issue: 15(5), P. 1223 - 1223

Published: May 17, 2025

Microbial agents play a crucial role in improving soil quality, increasing fertility, enhancing crop yields, and reducing the incidence of diseases. The ecological benefits these products contribute to environmental protection promotion sustainable agricultural development. Since beginning 21st century, research academic community on use microbial for improvement has increased, yet systematic summary progress this field is lacking. In paper, we review trends agent applications, focusing their classification, mechanisms action, practical implementations. To achieve this, conduct bibliometric analysis based SCI-EXPANDED database Web Science, using tools such as VOSviewer visualization. We focus analyze publication trends, hotspots, annual variations relevant studies published between 2003 2024. results show that (1) number publications steadily increased over years, indicating maintained high level interest field. Keywords “soil”, “diversity”, “carbon”, “nitrogen” have been central hotspots past 20 years. highly concentrated few countries, including China United States, well key institutions Chinese Academy Sciences States Department Agriculture.

The addition of mineral-solubilizing microbial inoculums is a kind biological measure for vegetation restoration rock mining areas. Its function to accelerate soil weathering, improve fertility, the ability plants fix soil. Through understanding response plant rhizosphere community inoculums, it helpful popularize use inoculums. However, little known about changes communities after Therefore, purpose this study was reveal pasthways through which different positively affect underground part R. pseudoacacia. A pot experiment conducted investigate responses bacterial and fungal in pseudoacacia by taking 32 samples from four treatments. results showed that effect on structure greater than community. But relative abundance Proteobacteria increased, had strong positive correlation with root nodulation. In terms diversity, diversity evenness It worth noting analysis Verrucomicrobia bacteria Ascomycota Zoopagomycota fungi were correlated enzyme activity growth. RDA these two phyla also effects Our can optimize structure, promote nodulation, enhance nitrogen fixation capacity plants. addition, provide theoretical basis application wide range slope ecological restoration.
