Article Abstract
The study clarified the succession of microbial community structures in fermented grains (FG) and their association with flavor compounds, along with their potential metabolic functions. The community diversity, functional genera and metabolites in FG were investigated by polyphasic detecting approaches. There are 13 dominant microorganisms in FG (relative abundance > 1%). Moisture and acidity are the key indicators driving the succession of microbial communities in FG. Eight kinds of microorganisms were involved in the metabolism of acid, higher alcohols and ethanol in FG and the abundance of pyruvate dehydrogenase and lactate dehydrogenase were significantly higher than other enzymes (P < 0.05). The results showed that 23 main flavor compounds were the results of the interaction of dominant microorganisms in FG. This study provides a basis for the formation of flavor substances in strong-flavor Baijiu.

Rapidly expanding nascent ecosystems at glacier forefields under climate warming dramatically enhance the terrestrial carbon (C) sink. Microbial C fixation and degradation, closely implicated in nitrogen (N) transformation and plant-soil-microbe interactions, significantly regulate soil C accumulation. However, how shifts in microbial functional potential impact soil C sequestration during vegetation succession remains unclear.

DNA literacy is becoming increasingly essential for navigating healthcare, understanding pandemics, and engaging with biotechnology-yet genomics education remains limited at the secondary level of education. We present a modular, hands-on curriculum designed for high school and early undergraduate students (ages 14-21) that introduces key genomics concepts through an experiment on fermentation, a process that is key to food preservation and medicine. Students follow a complete scientific process: exploring what DNA is and how microbial succession works, analyzing real DNA sequencing data, and writing a formal scientific report.

Unlabelled: This study explored the impact of green tea addition on bacterial communities in Moutai-flavored fermentation using high-throughput sequencing, alongside physicochemical and flavor analysis. Significant differences in microbial succession were observed over the 40-day fermentation period among types with varying tea proportions, resulting in distinct bacterial communities. Sixteen dominant genera, including , , and , were identified, with their relative abundances and succession patterns varying by type.

Microplastics (MPs) and the plastisphere they form pose substantial ecological risks in aquatic environments and wastewater treatment processes. As a unique niche, the evolution of plastisphere in anaerobic ammonium oxidation (anammox) systems remains poorly understood. This study investigated the physicochemical evolution of polyethylene terephthalate (PET) MPs and microbial succession within the plastisphere during a 30-day incubation with anammox granular sludge.

Tire microplastics (TMPs) represent a major contributor to microplastic pollution, posing threats to aquatic ecosystems. As carbon-rich substrates, TMPs influence microbial colonization and ecological functions. This study investigates the impacts of pristine (P-TMPs) and scrap (S-TMPs) TMPs from the same brand on microbial communities within the tire-plastisphere.
