Linking microbial community structure with molecular composition of dissolved organic matter during an industrial-scale composting

Jiangang Che et al.

Summary: This study investigated the interaction between dissolved organic matter (DOM) composition and microbial community structure during industrial-scale composting, revealing significant changes in both the molecular composition of DOM and microbial community structure. Network analysis identified Caldicoprobacter, Bacillus, and Dechloromonas as key players in the transformation process of DOM in composting, influencing the degradation of carbohydrates, acceleration of humification, and degradation of polycyclic aromatic hydrocarbons.

Identifying the Biogeographic Patterns of Rare and Abundant Bacterial Communities Using Different Primer Sets on the Loess Plateau

Quanchao Zeng et al.

Summary: High-throughput sequencing is commonly used for studying soil microbial communities, but the choice of primers targeting different regions of 16S rRNA can significantly impact the diversity and structure of microbial communities. This study found that the primer pairs 338f/806r and 520f/802r produced different results in assessing bacterial communities in soils of varying land uses. While primer pair 520f/802r showed no significant impact of land use on soil bacterial diversity, primer pair 338f/806r revealed distinct variations. Additionally, the soil bacterial diversity generated by primer pair 338f/806r was influenced by environmental factors, while primer pair 520f/802r showed no significant correlations.

Amount and biodegradation of dissolved organic matter leached from tree branches and roots in subtropical plantations of China

Jia-Wen Xu et al.

Summary: Overall, branches tended to leach lower amounts of DOC with lower aromatic content compared to roots, regardless of tree species. DOC quantity generally increased as diameter class decreased, while aromatic content showed an opposite trend for both branches and roots. Furthermore, DOM biodegradation increased with increasing diameter class, with branches exhibiting greater biodegradation compared to roots.

Temperature sensitivity of SOM decomposition is linked with a K-selected microbial community

Hui Li et al.

Summary: The temperature sensitivity (Q(10)) of soil organic matter (SOM) decomposition increases with mean annual temperature (MAT) but decreases with SOM bioavailability. The prevalence of K-strategy microbial communities in soil is associated with increased Q(10) values, indicating their important role in the decomposition of recalcitrant organic matter.

Environmental adaptation is stronger for abundant rather than rare microorganisms in wetland soils from the Qinghai-Tibet Plateau

Wenjie Wan et al.

Summary: Abundant microbes show stronger environmental adaptability and are less sensitive to changes, while rare microbes are more sensitive to environmental variations. Community assembly of abundant microbes is dominated by stochastic processes, while rare microbes are predominantly governed by deterministic processes.

Nutrient availability is a dominant predictor of soil bacterial and fungal community composition after nitrogen addition in subtropical acidic forests

Juyan Cui et al.

Summary: Nutrient addition, especially nitrogen, has significant impacts on belowground microbial diversity and community structure in subtropical forests. Bacterial alpha-diversity decreased significantly in subsoil with high nitrogen addition. Soil dissolved organic carbon decreased significantly after high nitrogen addition, while available nitrogen declined significantly after low nitrogen addition. Soil dissolved organic carbon was found to be the dominant factor influencing soil bacterial community composition, while available nitrogen and microbial biomass nitrogen were the best predictors of soil fungal community structure dynamics. These results provide evidence of shifts in soil microbial community structure in response to increasing nitrogen deposition in acidic subtropical forests.

Different responses of soil bacterial and fungal communities to nitrogen deposition in a subtropical forest

Jianqing Wang et al.

Summary: China has experienced a widespread increase in N deposition due to intensive anthropogenic activities, particularly in subtropical regions. The effects of long-term N deposition on soil bacterial and fungal abundance, diversity, and community composition show that fungi are more sensitive to N deposition, and soil N availability and pH are the most influential factors.

The chemodiversity of paddy soil dissolved organic matter is shaped and homogenized by bacterial communities that are orchestrated by geographic distance and fertilizations

Meng Wu et al.

Summary: This study utilized ultrahigh-resolution mass spectrometry to characterize the soil dissolved organic matter (DOM) chemodiversity and found that geographic distance has a greater impact on DOM diversity than anthropogenic fertilization. Long-term organic fertilization homogenizes DOM chemodiversity, while bacterial community diversity dictates the soil DOM chemodiversity.

Biodegradable dissolved organic carbon shapes bacterial community structures and co-occurrence patterns in large eutrophic Lake Taihu

Lei Zhou et al.

Summary: The proportion of biodegradable dissolved organic carbon (BDOC) in eutrophic lakes significantly influences bacterial community structures and co-occurrence patterns, with BDOC being a stronger factor than DOC quantity. Environmental factors have a greater explanatory power for the conditionally rare and abundant bacterial subcommunities than the abundant and rare subcommunities.

Long-term excess nitrogen fertilizer increases sensitivity of soil microbial community to seasonal change revealed by ecological network and metagenome analyses

Bing-Bing Li et al.

Summary: This study found that nitrogen fertilizer has an impact on soil microbial community structure and interaction, especially with long-term excess application. The fertilizer promoted certain metabolic processes while reducing other traits, making microbial networks more sensitive to environmental changes.
