Summary: This study investigated the variation of bacterial communities among different host genotypes in D. galeata water fleas and examined the relationship between genetic distance and bacterial community divergence. The results indicate that host genotype may shape the bacterial community structure, but genetic distances between hosts do not correlate with diverging bacterial communities.

Summary: The study found that the concentration of bacterial aerosols in the broiler house varied significantly in different seasons, with the highest concentration in summer and the lowest in winter. The composition of bacterial species also varied by season, with a higher proportion of Gram-negative bacteria in autumn. Additionally, the structure of potential pathogenic bacterial genera differed by season.

Summary: In desert-like areas of eastern Utah, bacterial community composition is significantly influenced by pH and organic matter concentration, with Proteobacteria and Gemmatimonadetes being the predominant phyla in high-altitude desert soils. The relative abundance of these phyla is correlated with soil pH and organic matter concentration, suggesting their importance in shaping bacterial community structure in these environments.

Summary: This study aimed to isolate lactic acid bacteria (LAB) from Chinese pickle and assess their effects on fermentation. Three LAB strains, L. fermentum FM 8, L. sp FM 10, and L. plantarum FM 17, were selected and inoculated in pickles. Pickles inoculated with L. fermentum FM 8 or L. plantarum FM 17 fermented faster and had lower nitrite levels. Sensory evaluation showed that pickles inoculated with L. plantarum FM 17 had the highest overall acceptability scores.

Summary: Fatty liver syndrome (FLS) is a common disease in high-producing dairy cows. This study aimed to generate primary data on healthy cows to serve as reference values for future research. The results showed that hepatic fat storage is a reversible process and does not necessarily cause clinical disease. However, older cows had a more sustained and greater increase in hepatic TAG concentration, which may explain their increased risk of FLS.

Summary: The study found multiple correlations between root morphology, root exudates, and rhizosheath fungal and bacterial communities, affecting plant phosphorus content and rhizosheath soil phosphorus concentration. Root exudation of carboxylates may play an important role in plant-soil-microbe interactions for phosphorus acquisition, potentially shaping microbial communities.

Summary: This study analyzed the seasonal variation of midgut bacterial diversity of Culex quinquefasciatus in southern China. The results indicated that the Bacteroidetes communities were more abundant in autumn and winter, potentially playing a role in the nutritional supply of adult mosquitoes when temperatures drop. The study provides valuable insights for disease control strategies targeting Cx. quinquefasciatus.

Summary: Soil pH conditions have significant effects on microbial community structure and functional activity. The acid-tolerant soil bacterium B. amyloliquefaciens MBNC showed enhanced antifungal activity under low pH conditions and produced surfactin homologues with varying chain length. The production of these metabolites was influenced by pH conditions, as well as the secretion of phytohormones by B. amyloliquefaciens MBNC. However, the isolate retained its antagonistic efficiency against fungal phyto-pathogens under acidic condition.

Summary: Pruning of tea trees affects the physicochemical and biological properties of tea garden soils, leading to soil sickness and decreased plant growth and productivity. Pruning reduces microbial abundance and richness in soil, but certain bacteria, such as Pseudomonas and Candidatus Solibacter, play important roles in plant growth and survival under stress conditions.

Summary: Potato plants have an interesting interaction with the microbial population in the geocaulosphere, which helps reduce the symptoms of common scab disease. The disease modulates the composition and abundance of the microbiome, but the core microbiome remains resilient. The plants selectively recruit beneficial microbes to fight against the pathogenic Streptomyces spp.

Summary: Long-term use of toxic pesticides has had adverse effects on the environment and human health. Microbe-mediated biodegradation is an effective strategy for removing contaminants in agriculture and promoting environmental sustainability. A Pseudomonas plecoglossicida strain (MBSB-12) isolated from imidacloprid-contaminated tea garden soil showed high efficiency in degrading the pesticide, reducing 87% of extractable imidacloprid from treated soil in 90 days. Further investigation is needed to understand the molecular mechanism of imidacloprid degradation by this strain.
