Summary: This study aimed to investigate the ability of four native herb species to remove polycyclic aromatic hydrocarbons (PAHs) in contaminated soils and analyze the associated bacterial community structures and functional genes. Results showed that all plant species were able to remove PAHs, with Kochia scoparia having the highest removal rate in the rhizosphere. The composition of bacterial community within the rhizosphere varied among plant species, and the presence of PAHs played a significant role in driving the composition of beneficial bacteria and the subsequent PAH rhizodegradation of native plants grown in coking plant.

Summary: This study explored the bacterial diversity of marine mucilage in the Marmara Sea and the North Aegean Sea using the metabarcoding approach. The results showed a diverse bacterial community dominated by Proteobacteria and Bacteroidetes species. The study also identified correlations between pH levels and the abundances of certain bacterial orders, as well as a positive correlation between total phosphorus and one bacterial order.

Summary: The distribution patterns of bacteria and archaea in the Bitahai peatland vary with soil depth, with total C and N increasing, while total P decreases. The community structure and diversity of archaea are significantly affected by soil C, N, and P concentrations, while this effect is not observed in bacteria.

Summary: The study found that the release of cry1Ab transgenic rice had effects on either the composition of bacterial communities or the abundance of microbial functional genes in the paddy soil. Although there were no differences in the alpha diversity indexes of the bacterial communities, the bacterial communities in the paddy soil with GM rice were separated from those of paddy soil with non-GM rice at each growth stage of rice, indicating significant differences in microbial communities between the two types of rice.

Summary: In a greenhouse study, the effects of Tuber indicum (Chinese black truffle) and T. lijiangense (Chinese white truffle) colonization on Castanopsis rockii host growth, physiological responses, and mycorrhizosphere bacterial communities were compared. Both truffle species increased leaf photosynthetic rate, leaf P concentration, acid phosphatase activity, and bacterial richness of the mycorrhizosphere. However, T. indicum colonization decreased tartrate content, bacterial acid phosphatase, phoC gene abundance, and peroxidase (POD) activity of ectomycorrhizal root tips, but increased mycorrhizosphere pH and superoxide dismutase (SOD) of ectomycorrhizal root tips compared to T. lijiangense colonization. Mycorrhizosphere bacterial community composition also differed significantly between the two truffle species. The bacterium Agromyces cerinus showed a significant correlation with acid phosphatase activity and leaf P concentration, indicating its potential role in phosphorus mobilization and acquisition.

Summary: Mixed blood meals have a synergistic effect on operational taxonomic unit richness and Shannon diversity index in mosquito gut microbiota. Host species identity and mixed blood-feeding are key determinants of microbial community composition. Microenvironmental conditions play an important role in structuring mosquito gut microbial communities.

Summary: This study examined the impact of soil microbial community and oxygen availability on moisture content, soil pH, and bacterial composition during the decomposition of poultry carcasses. The research found that bacterial taxa composition varied between different burial set-ups and across time points, with differences in the dominant phyla and genera at different stages of decomposition. The presence of intact microbial communities and oxygen significantly affected the changes in moisture content, pH, and bacterial composition throughout the decomposition process.

Summary: This study aims to investigate the dynamics of earthworm gut microbiota during vermicomposting. The results showed that the dynamics of foregut and hindgut bacteria differed in terms of diversity, composition, and structure, which were related to changes in nutrient provision. Day 3 was a crucial turning point, with little overlap in abundant bacteria between the foregut and hindgut. At the end of vermicomposting, a stable bacterial structure appeared in the hindgut, while the foregut exhibited a more muddled structure. Understanding the dynamics of earthworm gut microbiota is essential for improving the efficiency of organic waste vermicomposting.

Summary: This study investigated the changes in bacterial abundance, community composition, and diversity under different N application rates in a water-limited area. The results showed that N application significantly affected bacterial abundance, community composition, and structure, as well as the functions of bacterial community. Bacterial diversity was enhanced at low N application rates, but reduced at higher N application rates.

Summary: The study characterized the biofilm microbial community causing corrosion of API 5LX carbon steel, dominated by Proteobacteria such as Marinobacter hydrocarbonoclaustic and Marinobacter alkaliphilus. The biofilm accelerated corrosion by twofold and fourfold compared to control treatment, with thick biofilm and pitting corrosion observed. X-ray diffraction confirmed that the microbial biofilm heavily oxidized iron, contributing to the acceleration of corrosion.
