“…Aliidongia dinghuensis , a gram-negative bacterium, was found in soil samples of Pinus massiniana plantations; this bacterium produced poly-β-hydroxybutyrate and can be applied to the biodegradable plastics industry [ 34 ]. Discovering soil bacterial communities in the bulk soil and rhizosphere soil of Carya cathayyensis influenced by root rot disease showed that the relative abundance of the Aliidongia genus was higher in bulk soil than in rhizosphere soil [ 59 ]. The abundance of Aliidongia in boreal forest soil was also significantly affected by harvesting and forest floor removal [ 60 ].…”

Pollutants can exist in the soil for a long time and alter the bacterial community. Using lubricants to prevent the wear of chainsaw blades is necessary for thinning activities and wood harvesting. We investigated the influences of soil contamination with chainsaw lubricants on soil bacterial communities. Bio-oil, mineral oil, and recycled oil were scattered on each treatment to investigate variations in soil bacterial structure during treated periods using the Illumina MiSeq sequencing platform. The results obtained were 5943 ASVs, 5112 ASVs, and 6136 ASVs after treatment at one month, six months, and twelve months, respectively. There was a significant difference in Shannon and Simpson indices between treatments and controls. A total of 46 bacterial genera with an average relative abundance of more than 1.0% were detected in all soil samples. Massilia was the most common genus detected in control at one month, with an average relative abundance of 14.99%, while Chthoniobacter was the most abundant genus detected in bio-oil, mineral oil, and recycled oil treatments at one month, with an average relative abundance of 13.39%, 14.32%, and 10.47%, respectively. Among the three chainsaw lubricants, bio-oil and mineral oil had fewer impacts than recycled oil. The abundances of several functional bacteria groups in the bio-oil treatment were higher than in other treatments and controls. Our results indicated that different chainsaw lubricants and their time of application affected the soil bacterial community composition.

Sustainable food production systems in developing countries require resilient production of crops like Zea mays (maize) with understanding of its rhizosphere bacteriome. Maize rhizospheres in six locations, representing two main hemispheres (southern: Ma2R, Ma3R, and BaMR; northern: MF1A-R, MF2A-R, and MF3A-R), were assessed for geochemistry and 16S rRNA microbiome. The pH of the rhizospheres tends mostly towards acidic (6.33–6.98) with some significant variations (p < 0.05) in the geochemical features across the locations. Varied concentrations of organochlorine compounds were observed in the rhizospheres, where endrin was recorded in all the rhizospheres. The dominance of Proteobacteria, Actinobacteria, Firmicutes, Acidobacteria, Chloroflexi, Plactomycetes, Verrucomicrobia, and Bacteroidetes with apparent variations was observed across the locations. Firmicutes (as evidenced with Bacillus fumarioli group) varied significantly between MF2A-R and MaMR (t = 2.96; p < 0.05), Ma3R (t = 3.99; p < 0.01), and Ma2R (t = 3.13; p < 0.05). Remarkably, Proteobacteria (represented by Bradyrhizobium japonicum group) was relatively higher in the maize rhizosphere from the southern (Ma2R, 24.8%; Ma3R, 37.8%; BaMR, 37.6%) than in northern (MF1A-R, 22.1%; MF2A-R, 25.6%; MF3A-R, 27.1%) hemispheres. Contrariwise, the abundance of Acidobacteria (mostly unclassified species), Chloroflexi and Actinobacteria skewed towards maize rhizospheres in the northern sphere indicating oligotrophic ecosystem. The phylogenetic Diversity index revealed Ma2R was the most diverse phylotypes with a 5142-factor followed by MF1A-R (4957), Ma3R (4949), MF2A-R (4465), MF3A-R (4440), and the least diverse was BaMR (4284). Canonical correspondence analysis and other beta-diversity indexes established a 19.6% variance between the southern and northern rhizosphere as the bacteriome related to environmental fluxes through 64.4% variability.

Different land‐use practices in temperate forests strongly affect soil quality and soil microbial communities, whereas the assembly and interactions of soil functional fungal communities provide positive feedback. Therefore, the effects of forest ecosystem degradation on the composition of functional soil fungal community and soil nutrient cycling are of particular importance. We studied forest ecosystems in the Liupanshan Mountains in the northwestern part of the Loess Plateau and analyzed the relationship of soil fungal community and soil nutrient cycling under different land use practices (natural forest [NF], plantation forest, and farmland [FL]). The results showed that soil pH and electrical conductivity were the highest in FL, whereas the soil carbon cycle index and nitrogen cycle index decreased. The soil total phosphorus content did not change significantly with an increase in available phosphorus content. The change from NF to FL significantly increased the number of operational taxonomic units, diversity, and richness of soil fungal communities. The composition of the soil fungal communities was also strongly influenced by carbon and nitrogen cycle indices. In addition, FL reclamation increased the complexity of the soil microorganism co‐occurrence network, and the interrelationships between soil functional fungal community were enhanced. Pathogenic fungal communities were enriched in FLs, and their relative abundance was significantly regulated by environmental factors such as pH and the ratio of nitrogen to phosphorus. The soil pathogenic fungal community affected carbon and nitrogen cycle indices to varying degrees.
