Abstract Purpose To understand which environmental factors influence the distribution and ecological functions of bacteria in agricultural soil. Method A broad range farmland soils was sampled from 206 locations Jilin province, China. We used 16S rRNA gene-based Illumina HiSeq sequencing to estimated soil bacterial community structure functions. Result The dominant taxa terms abundance were found be, Actinobacteria, Acidobacteria, Gemmatimonadetes, Chloroflexi, Proteobacteria. Bacterial communities dominantly affected by pH, whereas organic carbon did not have a significant on communities. Soil pH significantly positively correlated with operational taxonomic unit α-diversity (P<0.05) spatially rather than nutrients. using FAPROTAX, relative anaerobic aerobic chemoheterotrophs, nitrifying 27.66%, 26.14%, 6.87%, respectively, total community. Generally, results indicate that is more important nutrients shaping soils, including their biogeographic distribution.

Assessment of heavy metal pollution and the effect on bacterial community in acidic and neutral soils

Ecological Indicators, Год журнала: 2020, Номер 117, С. 106626 - 106626

Mining activities have caused heavy metal pollution in Xikuangshan (XKS), China. This work aims to assess ecological risk XKS using a potential (PER) index and detect the responses of soil bacterial community under stress at different pH levels. The PER indicated that antimony (Sb), cadmium (Cd), arsenic (As) posed most serious sampling sites. We compared effects metals on structure microbial acidic neutral conditions. Our results suggested significant differences between soils. Zinc (Zn) lead (Pb) were main factors affecting conditions, whereas effect Sb, As, chromium (Cr) exceeded them was possibly due characteristics their interactions with properties. genus positively correlated Zn, Pb, Cd both soils, which may increasing resistance conditions long-time pollution. our structural equation modeling variations mainly explained by nutrients also had direct influences as well indirect impact Several metal-resistant bacteria can be used for remediation acid

Soil pH: a key edaphic factor regulating distribution and functions of bacterial community along vertical soil profiles in red soil of pomelo orchard

BMC Microbiology, Год журнала: 2022, Номер 22(1)

Опубликована: Фев. 2, 2022

Abstract Background Soil microbes exist throughout the soil profile and those inhabiting topsoil (0–20 cm) are believed to play a key role in nutrients cycling. However, majority of microbiology studies have exclusively focused on distribution microbial communities topsoil, it remains poorly understood through subsurface (i.e., 20–40 40–60 cm). Here, we examined how bacterial community composition functional diversity changes under intensive fertilization across vertical profiles [(0–20 cm (RS1), (RS2), (RS3)] red pomelo orchard, Pinghe County, Fujian, China. Results Bacterial was determined by 16S rRNA gene sequencing interlinked with edaphic factors, including pH, available phosphorous (AP), nitrogen (AN), potassium (AK) investigate factors that shape along different profiles. The most dominant taxa were Proteobacteria , Acidobacteria Actinobacteria Chloroflexi Crenarchaeota, Bacteriodetes . richness highest RS1 declined increasing depth. distinct patterns found Besides, pH exhibited strong influence (pH ˃AP ˃AN) all depths. relative abundance Proteobacteria, Actinobacteria, Firmicutes negatively correlated while Acidobacteria, Chloroflexi, Bacteriodetes, Planctomycetes, Gemmatimonadetes positively pH. Co-occurrence network analysis revealed topological features weakened depth, indicating more stable RS1. functions estimated using FAPROTAX related metabolic processes, C-cycle, N-cycle, energy production significantly higher compared RS2 RS3, had significant effect these microbes. Conclusions This study provided valuable findings regarding structure orchards, highlighted importance depth shaping population, their spatial ecological functioning. These results suggest alleviation acidification adopting integrated management practices preserve for better

Crop rotations increased soil ecosystem multifunctionality by improving keystone taxa and soil properties in potatoes

Frontiers in Microbiology, Год журнала: 2023, Номер 14

Опубликована: Фев. 23, 2023

Continuous cropping of the same crop leads to soil degradation and a decline in production, these impacts could be mitigated through rotation cropping. Although enhances fertility, microbial community diversity, potato yield, its effects on ecosystem multifunctionality (EMF) remain unclear. In present research, we comparatively examined continuous (PP) [potato-oat (PO) potato-forage maize (PFM)] EMF as well roles keystone taxa, microbes abundance, chemical properties improvement. It was demonstrated that is increased (PO PFM) than PP. Soil pH higher PP, while total phosphorus (TP) available (AP) were significantly decreased Rotation markedly changed bacterial fungal compositions, improved potential plant-beneficial fungi, e.g., Schizothecium Chaetomium, reducing abundances potentially phytopathogenic Alternaria, Fusarium, Verticillium dahiae, Gibberella, Plectosphaerella, Colletotrichum, Phoma, Lectera comparison with Also, co-occurrence patterns for bacteria fungi impacted by rotation, Nitrospira.1, Lysinibacillus, Microlunatus.1, Sphingomonas.3, Bryobacter.1, Micromonospora, Schizothecium, enriched PO PFM The structural equation model (SEM) further systems regulating SOM taxa (Schizothecium1), mediated pH. This study suggested might contribute improvement development disease-suppressive soils

Low-density polyethylene microplastics alter chemical properties and microbial communities in agricultural soil

Scientific Reports, Год журнала: 2023, Номер 13(1)

Опубликована: Сен. 28, 2023

Microplastic (MP) pollution in agricultural soils, resulting from the use of plastic mulch, compost, and sewage sludge, jeopardizes soil microbial populations. However, effects MPs on chemical properties communities remain largely unknown. Here, we investigated different concentration levels (0, 0.1, 1, 3, 5, 7%; w:w) low-density polyethylene (LDPE) bacterial an incubation study. The addition LDPE did not drastically change pH (ranging 8.22 to 8.42). Electrical conductivity increased significantly when MP concentrations were between 1 7%, whereas total exchangeable cations (Na+, K+, Mg2+, Ca2+) decreased at higher (3-7%). highest available phosphorus content (2.13 mg kg-1) was observed 0.1% MP. Bacterial richness (Chao1 Ace indices) lowest MP, diversity indices (Shannon Invsimpson) 0 1% than other concentrations. effect phyla remained unchanged, but abundance varied. relative Proteobacteria (25.8-33.0%) all treatments. Acidobacteria (15.8-17.2%) also high, particularly 0, MPs. With increase concentration, Actinobacteria gradually 7.80 31.8%. Our findings suggest that considerably alter composition, which may potentially ecological functions ecosystems.

Mimicking real-field degradation of biodegradable plastics in soil and marine environments: From product utility to end-of-life analysis

Polymer Testing, Год журнала: 2024, Номер 131, С. 108338 - 108338

Опубликована: Янв. 21, 2024

Biodegradable plastics can mitigate plastic waste issues by undergoing hydrolysis and microbial digestion. However, biodegradable face unjust accusations of not decomposing in natural environments, including barren soil or cold oceans, under unsuitable conditions. In this study, we simulated end-of-life products real-field seawater Replenishing vermicompost horticultural topsoil (3:7 wt ratio) activated growth, resulting significant degradation. fertile soil, polycaprolactone (PCL) poly(butylene succinate) (PBS) required fewer than 6-months, for complete degradation, while adipate-co-terephthalate) (PBAT) with more 51 mol% terephthalate content was rarely degraded. an artificial aquarium, PCL degraded at the rate 30 μm per month. The degradation bioplastics enclosed coarse nets superior to that fine nets, owing higher aeration water circulation. Sea waves current significantly accelerated PCL-degradation 89 month a coastal marine environment; ranking decomposition > PBS PBAT. After 12 months biodegradation, tensile strength elongation 2 mm-thick sample decreased 15 MPa almost 0 %, respectively. 3D-printed jars, designed octopus fishing, is widely used its mechanical decay aids preventing ghost fishing abandoned gear as demonstrated conches, illustrating potential gear.
