The threat of microplastic (MP) pollution soil ecosystems has aroused global concern; however, relatively few studies have focused on the effects MPs both bacterial and fungal communities in soil. In this study, a 310-day incubation experiment was designed to examine 7% 14% (W/W) polyethylene (PE), polystyrene (PS), polyvinyl chloride (PVC) enzyme activities as well communities. findings revealed that all three kinds stimulated activities, with PVC, PS, PE having greatest impact catalase, urease, alkaline phosphatase. did not change types but relative abundance these phyla mainly increased Proteobacteria, Actinobacteria, Ascomycota declined Acidobacteria, Basidiomycota, Chytridiomycota. response fungi stronger than bacteria, diversity more sensitive PVC had microbial PICRUSt analysis promoted metabolic function bacteria. Based FUNGuid tool, it found significant fungi, which were closely related plant growth. These results indicate depends type concentration bacteria are affected differently by MPs.

New insights into carbon mineralization in tropical paddy soil under land use conversion: Coupled roles of soil microbial community, metabolism, and dissolved organic matter chemodiversity

Geoderma, Journal Year: 2023, Volume and Issue: 432, P. 116393 - 116393

Although the impact of land conversion on carbon mineralization in paddy soils has received increasing attention, coupled roles soil microdiversity and chemodiversity these processes are largely unknown. To address this issue, use from fields (PF) to vegetable (VF), rice-vegetable rotation (RV), abandoned (AL), were investigated study. The relationships between characteristics microbial community, metabolism physiology dissolved organic matter (DOM) analyzed. After conversion, enhanced AL RV, which 217.49% 183.02% that PF. In contrast, no significant change was observed VF, although anaerobic environment transformed into an aerobic one fungal richness/ diversity increased soil. This because directly regulated by DOM quantity labile carbon, indirectly community. Specifically, largest attributed strongest as had DOC contents, hydrophilic substances (e.g., carboxyl, carbohydrate, amino), abundant eutrophic taxa Actinobacteria Proteobacteria). VF mainly related more condensed aromatics oligotrophic microbes, fewer soil, resulting dominance recalcitrant carbon. also prevailed RV. However, RV showed moderate due having proper with high bioavailability. Collectively, results provide molecular insights a micro-chemodiversity perspective, highlights importance nutrient supply strategy.

Abundant fungal and rare bacterial taxa jointly reveal soil nutrient cycling and multifunctionality in uneven-aged mixed plantations

Ecological Indicators, Journal Year: 2021, Volume and Issue: 129, P. 107932 - 107932

Published: June 28, 2021

Uneven-aged silvicultural practices can maintain habitat continuity and enhance biodiversity. Soil microorganisms play critical roles in multiple ecosystem functions (i.e., multifunctionality). However, little is currently known regarding the role of microbial community driving soil nutrient cycling multifunctionality (SMF) uneven-aged mixed plantations. In this study, we investigated bacterial fungal compositions diversities, single-function related carbon (C), nitrogen (N), phosphorus (P) cycling, SMF indices monoculture plantation (as a control) three stands (4, 7, 11 years old). Our results demonstrated that C, N, P plantations increased by 17.9–55.2%, 20.0–54.0%, 0.7–21.6%, 16.3–30.1% compared to plantation. The alpha diversity (richness Shannon diversity), significantly improved with stand age, but showed less variation. beta diversities bacteria fungi notable variation age were predominantly affected properties (soil organic total P, C/N ratio), respectively. Additionally, temporal turnover within was higher than rates community. biomass more sensitive structure change over short period (11 years) biomass. Furthermore, fungi/bacteria (F/B) ratio strongly positively correlated SMF. Most importantly, abundant taxa (e.g., Mucoromycota Mortierellomycota) major drivers SMF, followed rare Nitrospirae Elusimicrobia). These findings indicate communities have different responses undertake important maintaining when converted into an

The Shift of Soil Bacterial Community After Afforestation Influence Soil Organic Carbon and Aggregate Stability in Karst Region

Frontiers in Microbiology, Journal Year: 2022, Volume and Issue: 13

Published: June 27, 2022

Soil microbes regulate the carbon cycle and affect formation stabilization of soil aggregates. However, interactions between microbial community organic (SOC) fractions, (OC) content in aggregates, aggregate stability after afforestation are remain poorly understood. In our study, we investigated SOC fractions bulk soil, aggregate-associated OC content, stability, bacterial with high-throughput 16S rRNA sequencing at sites representing natural secondary forest (NF) managed (MF), cropland (CL) as reference a degraded karst region Southwest China. Our results showed that remarkably increased fraction mean weight diameter (MWD), geometric (GMD). The most dominant phyla detected were Acidobacteriota , Actinobacteriota Proteobacteria Chloroflexi across all soils. Afforestation altered relative abundances bacteria phylum, class, order levels. Interestingly, such changes abundance taxa had significantly effects on fraction, MWD, MGD. Methylomirabilota Latescibacterota Methylomirabilia MB-A2-108 norank_Latescibacterota ; Dehalococcoidia Rokubacteriales Gaiellales Microtrichales norank_c__MB-A2-108 norank_c__norank_p__Latescibacterota Rhizobiales S085 not only but also significant positive afforestation. Moreover, MWD MGD positively correlated . Results indicated importance certain for regulating storage stability. We concluded could alter bacteria, these modulate aggregates fractions.
