Soil microbial communities regulate the threshold effect of salinity stress on SOM decomposition in coastal salt marshes

Fundamental Research, Год журнала: 2023, Номер 3(6), С. 868 - 879

Опубликована: Март 20, 2023

Salinity stress is one of the critical environmental drivers soil organic matter (SOM) decomposition in coastal ecosystems. Although temperature sensitivity (Q10) SOM has been widely applied Earth system models to forecast carbon processes, impact salinity on by restructuring microbial communities remains uncovered. Here, we conducted a microcosm experiment with soils collected from salt marsh Yellow River Estuary, which subjected strong dynamics due both tidal flooding and drainage. By setting gradient solutions, was adjusted simulate emission (CO2) rate measured over period. Results showed that as increased, estimated constants based first-order kinetics gradually decreased at different temperatures. Below 20‰ treatments, doubled salinity, Q10 increased increasing salinity; but higher constrained temperature-related response inhibiting growth metabolisms. Soil bacteria were more sensitive than fungi, can be inferred beta-diversity changing salinity. Among them, phylotypes assigned Gammaproteobacteria Bacilli tolerance, whereas taxa affiliated Alphaproteobacteria Bacteroidota easily inhibited stress. Several fungal belonging Ascomycota had adaptability As substrate consumed incubation, bacterial competition intensified, co-occurrence pattern changed weakly during decomposition. Collectively, these findings revealed threshold effect marshes emphasized plays key role sequestration regulating keystone taxa, metabolisms, interactions.

Multikingdom interactions govern the microbiome in subterranean cultural heritage sites

Proceedings of the National Academy of Sciences, Год журнала: 2022, Номер 119(15)

Опубликована: Март 28, 2022

Significance The conservation of historical relics against microbial biodeterioration is critical to preserving cultural heritages. One major challenge our limited understanding microorganisms’ dispersal, colonization, and persistence on after excavation opening external environments. Here, we investigate the ecological physiological profiles microbiome within outside Dahuting Han Dynasty Tomb with a 1,800-y history. Actinobacteria dominate in this tomb. Via interkingdom signaling mutualism, springtails carry as one possible source into tomb from surrounding Subsequently, produce cellulases combined antimicrobial substances, which helps them colonize thrive via intrakingdom competition. Our findings unravel ecology microbiomes colonizing provide help for practices.

Tea Plantation Intercropping Legume Improves Soil Ecosystem Multifunctionality and Tea Quality by Regulating Rare Bacterial Taxa

Agronomy, Год журнала: 2023, Номер 13(4), С. 1110 - 1110

Опубликована: Апрель 13, 2023

Microorganisms play essential roles in soil-ecosystem multifunctionality. However, the contribution of their community assembly processes, composition, diversity, and keystone species to ecosystem multifunctionality is unclear, especially tea-plantation ecosystems. In order assess effects various intercropping patterns (tea-plant monoculture tea plants, respectively, intercropped with soybean, soybean—milk vetch, soybean—red clover, soybean—smooth vetch) on soil rare abundant taxa, a field experiment was carried out. We found that plantation legumes improved by altering environment, ultimately benefited nutrient absorption quality improvement leaves. Whether it bacteria or fungi, taxa had higher proportion deterministic processes than taxa. Additionally, practices changed bacterial were assembled shifted from variable selection homogeneous dispersal. Intercropping significantly fungal communities’ α-diversity Increasing legume practice enhanced dissimilarity affecting pH, ammonium nitrogen, nitrate nitrogen. Rare β-diversity exhibited stronger positive relationships (both average multi-threshold approaches) compared corresponding Furthermore, under different closely related operational taxonomic units, Chloroflexi. Our results emphasize disparate feedbacks diverse practices, as well important connection between

Rhizo-microbe recruited by hyperaccumulating plants are crucial for the extraction of metals from contaminated soils. It is important, but difficult, to identify specific rhizosphere microbes hyperaccumulators shaped root exudation. Continuous 13CO2 labeling, microbial DNA-based stable isotope probing (DNA-SIP), and high throughput sequencing were applied those microorganisms using exudates Cd hyperaccumulator Sedum alfredii. In contrast its non-hyperaccumulating ecotype (NAE), (HAE) S. alfredii strongly changed environment extracted a 5-fold higher concentration soil. Although both HAE NAE harbored Streptomyces, Massilia, Bacillus, WPS-2 Uncultured Bacteria with relative abundance more than 1% in associated plant growth immunity, specifically Rhodanobacter (2.66%), Nocardioides (1.16%), Burkholderia (1.01%) through benefit Different bacterial network weak cooperation rhizosphere, closed-loop was established synergistically resist Cd. This research reveals community induced assisted provides new perspective regulation rhizo-microbe beneficial optimizing phytoremediation.

The Impacts of the C/N Ratio on Hydrogen Sulfide Emission and Microbial Community Characteristics during Chicken Manure Composting with Wheat Straw

Agriculture, Год журнала: 2024, Номер 14(6), С. 948 - 948

Опубликована: Июнь 18, 2024

Wheat straw (WS) has long been subjected to rough treatment by traditional incineration, which not only results in the waste of biomass resources but also poses a risk atmospheric pollution and is conducive sustainable utilization natural resources. With great humification potential, WS can be utilized as valuable composting material. The study optimized C/N ratio mixing chicken manure (CM) raw materials, found that this method could significantly improve compost quality. In comparison conventional poplar woodchip (PW) conditioning, incorporation resulted an elevated temperature, extended high-temperature period, more expeditious lignocellulose degradation, notable enhancement organic matter content, suppression hydrogen sulfide production under low ratio, promotion elemental sulfur conversion, collectively contributing enhanced overall quality environmental friendliness compost. Correlation analysis microbial communities factors demonstrated mixed facilitated growth actinomycetes sulfur-transforming bacteria. Additionally, structural equation model indicated parameters such temperature pH value played key role process.
