Summary: A novel actinomycete strain OK19-0408T was isolated from soil collected on Iheya island, Okinawa prefecture, Japan. Phylogenetic analysis revealed that it is closely related to Amycolatopsis vancoresmycina JCM12675T, but DNA-DNA hybridization analysis indicated low relatedness between strain OK19-0408T and these closely related strains. Based on its distinct characteristics, it is proposed as a new species named Amycolatopsis iheyensis.

Summary: This study aimed to investigate the impact of pulmonary TB on glycemic status, as well as the associations of glycemic trends with antidiabetic therapy and TB outcomes. Data from two prospective cohort studies in Chennai, India were analyzed and it was found that baseline A1C levels decreased after TB treatment initiation in all groups. However, in patients with baseline diabetes, rising A1C levels during and after treatment were significantly associated with adverse TB outcomes.

Summary: Two clinopyroxene megacrysts, DMP-2 and DMP-3, from Cenozoic alkali basalts in Hannuoba region of China were characterized for major and trace element compositions through in situ microanalysis. Both clinopyroxene samples showed homogeneity in element mass fractions based on EPMA and LA-ICP-MS analyses. Bulk analyses using XRF, ICP-OES and solution ICP-MS techniques also revealed consistent major and trace element data. Thus, these samples can serve as potential reference materials for elemental in situ microanalysis, with recommended element mass fractions for thirty-two elements.

Summary: This study investigated the distribution and potential functions of prokaryotes in different saline lakes in Xinjiang using the cultivation-independent method of amplicon sequencing. The results showed that Proteobacteria was the predominant community in all types of saline lakes, while Desulfobacterota, Firmicutes, Acidobacteriota, and Chloroflexi were mainly distributed in hypersaline, arid saline, and light saltwater lakes respectively. The functional group analysis revealed that fermentation was the main metabolic process of microbes in all saline lakes. Environmental factors such as SO42-, Na+, CO32-, and TN were found to significantly affect the microbial community.

Summary: This study found that fluctuating temperature has a positive effect on species diversity in soil bacterial communities compared to constant temperatures, and it also affects bacterial performances. The analysis showed that fluctuating temperature can delay species loss, and temperature-responsive species exhibit performance deviations under fluctuating temperature compared to constant temperatures. Additionally, the effects of fluctuating temperature on species diversity in soil bacterial communities may vary across latitude.

Summary: By reconstructing 10 closely related metagenome-assembled genomes from hot spring habitats, we discovered a new species, Panguiarchaeum symbiosum. Our functional investigations revealed that Panguiarchaeum symbiosum is an anaerobic organism that exclusively grows in thermal habitats by fermenting peptides and producing sulfide and hydrogen. The species likely lives in a symbiotic lifestyle similar to DPANN archaea. Population metagenomics and metatranscriptomic analyses supported the proposed proteolytic catabolism and symbiotic lifestyle of Panguiarchaeum symbiosum. This study provides insights into the metabolism, evolution, and potential symbiotic lifestyle of this unique archaeon within the TACK superphylum.

Summary: In this study, the dynamics of microbial and viral communities in an expanded granular sludge bed (EGSB) reactor were investigated. The results showed that COD, VSS/TSS ratio, and temperature were the main factors affecting the microbial community structure. The study also identified key genes involved in nitrogen cycling, with the dissimilatory nitrate reduction to ammonia (DNRA) and denitrification pathways dominating in the anaerobic system. The findings provide insights for the optimization of engineered systems.

Summary: The candidate bacterial phylum Omnitrophota is poorly studied. By analyzing genomes and data from the Earth Microbiome Project, researchers found that Omnitrophota are ultra-small cells mainly found in water, sediments, and soils. These bacteria have reduced genomes but retain key metabolic pathways and symbiotic gene clusters, indicating a host-associated lifestyle. Additionally, stable-isotope probing identified certain Omnitrophota families as potential obligate bacterial predators. Overall, most Omnitrophota inhabit various ecosystems as predators or parasites.

Summary: By using genome-resolved metagenomics, researchers discovered 28 Parvarchaeales-associated metagenome-assembled genomes (MAGs) and identified metabolic differences between Jingweiarchaeales and Parvarchaeales, as well as the adaptation of Parvarchaeales to acidic environments. The study also revealed unique genomic features of Jingweiarchaeum and Haiyanarchaeum that may contribute to their adaptation to high-temperature environments. Overall, this research is important for understanding the strategies and processes of how Candidatus Parvarchaeales microbes adapt to extreme environments.
