Abstract Animal manure comprises an important reservoir for antibiotic resistance genes (ARGs), but the variation in ARGs during anaerobic digestion at various temperatures and its underlying mechanism remain unclear. Thus, we performed using dairy three temperature levels (moderate: 20 °C, mesophilic: 35 °C thermophilic: 55 °C), to analyze dynamics of bacterial communities by quantitative PCR 16S rRNA gene sequencing. We found that 8/10 detected declined 5/10 decreased more than 1.0 log...

Agricultural ecosystems are facing increasing environmental changes. Revealing ecological stability of belowground organisms is key to developing management strategies that maintain agricultural ecosystem services in a changing world. Here, we collected soils from adjacent pairs maize and rice fields along large spatial scale across Eastern Southeast China investigate the importance core microbiota as predictor resistance soil microbiome (e.g. bacteria, fungi protist) climate changes...

Abstract Agriculture contributes to a decline in local species diversity and above- below-ground biotic homogenization. Here, we conduct continental survey using 1185 soil samples compare microbial communities from natural ecosystems (forest, grassland, wetland) with converted agricultural land. We combine our results global meta-analysis of available sequencing data that cover more than 2400 across six continents. Our combined demonstrate land conversion taxonomic functional homogenization...

Abstract Background Soil is an important reservoir of antibiotic resistance genes (ARGs), but their potential risk in different ecosystems as well response to anthropogenic land use change unknown. We used a metagenomic approach and datasets with well-characterized metadata investigate ARG types amounts soil DNA three native ecosystems: Alaskan tundra, US Midwestern prairie, Amazon rainforest, the effect conversion latter two agriculture pasture, respectively. Results High diversity (242...

Abstract Microbes inhabiting deep soil layers are known to be different from their counterpart in topsoil yet remain under investigation terms of structure, function, and how diversity is shaped. The microbiome soils (>1 m) expected relatively stable highly independent climatic conditions. Much less known, however, on these microbial communities vary along climate gradients. Here, we used amplicon sequencing investigate bacteria, archaea, fungi fifteen 18‐m depth profiles at 20–50‐cm...

Composting is an effective method for disposing of plant and animal manure, including apple tree branches. In this study, effects temperature, enzyme activity, microbial community diversity were investigated in high-temperature aerobic composting using pig manure branches as the experimental materials. This study showed that a compound inoculum (Ralstoinia sp., Penicillium aurantiogriseum, Acremonium alternatum) could improve temperature extend period decomposition by 4 days. Compared with...

Significance Estimating risk from environmental resistome is hindered by the lack of data on its mobility and host range, as well whether it likely functional. We developed an enrichment analysis method using long-read sequencing technologies to link mobilome correlate these with range a sample representative source that had exposure medically important antibiotic. The long reads provide for detection complete genes, direct evidence their physical linkages assessing coselection, chromosomal...

Allelopathy is closely associated with rhizosphere biological processes, and microbial communities are essential for plant development. However, our understanding of rhizobacterial under influence allelochemicals in licorice remains limited. In the present study, responses effects on allelopathy were investigated using a combination multi-omics sequencing pot experiments, allelochemical addition inoculation treatments.
