Soil dissolved organic matter (DOM) is mainly derived from the microbial degradation of matter. Intense freeze–thaw cycles (FTCs) elicited by warming alter production and consumption DOM in boreal forest soils, but little known about interactions between soil community chemical composition. In this study, a FTCs incubation experiment was conducted to investigate association dynamics community. fingerprints were characterized using pyrolysis gas chromatography-mass spectrometry (Py-GC/MS) technology, bacterial fungal composition analyzed high-throughput sequencing bioinformatics. Both two six (2FTCs 6FTCs) significantly increased carbon (DOC) NH4+-N contents at 0–10 cm 50–60 depths. decreased relative abundance aromatic components DOM, whereas increasing polysaccharides fatty acid methyl esters (FAMEs) DOM. The lignin-derived compounds accelerated microbial-derived accumulated. Also, responded more sensitively than Significant changes network observed during with linkages, shortened average path lengths, reduced modularity dominant phyla, α diversity. However, only length higher connectivity indicated that enhanced components. led shift keystone taxa being present specific molecules competing for common substrates. Overall, tended activate increase availability, which could promote turnover C stabilization. These findings provide new insights into molecular mechanisms soils under FTCs.

Effects of Bacillus subtilis and Pseudomonas fluorescens as the soil amendment

Heliyon, Год журнала: 2022, Номер 8(11), С. e11674 - e11674

The application of soil beneficial bacteria (SBB) in agriculture is steadily increasing as it provides a promising way to replace chemical fertilisers and other supplements. Although the role SBB biofertiliser well understood, little known about response physiochemical properties via change enzymatic activities with growth. In this study, sterilised bulk was inoculated Bacillus subtilis (BS) Pseudomonas fluorescens (PF), which exhibit excellent characteristics vitro for potentially improving quality. It found that contents bioavailable nitrogen ammonium increased significantly, up 34% 57% relative control. This resulted from enhancement urease activity BS PF treatments by approximately 90% 70%, respectively. can be explained microorganism evident larger population size (0.78–0.97 CFU mL−1/CFU mL−1) than (0.55–0.79 (p < 0.05). Results principal component analysis also reinforce interaction apparent significant relationship between microbial biomass carbon Therefore, concluded induced fertility upregulation because bacterial These results demonstrate strategy amendment, particularly nutrient restoration.
