Research Article | Applied and Environmental ScienceStructural and Functional Changes in Prokaryotic Communities in Artificial Pit Mud during Chinese Baijiu ProductionStrong-flavor baijiu (SFB) accounts for more than 70% of all Chinese liquor production. In the Chinese baijiu brewing industry, artificial pit mud (APM) has been widely used since the 1960s to construct fermentation cellars for production of high-quality SFB. To gain insights at the systems level into the mechanisms driving APM prokaryotic taxonomic and functional dynamics and into how this variation is connected with high-quality SFB...
Special Issue Perspective | Host-Microbe BiologyMetaproteomics: Much More than Measuring Gene Expression in Microbial CommunitiesMetaproteomics is the large-scale identification and quantification of proteins from microbial communities and thus provides direct insight into the phenotypes of microorganisms on the molecular level. Initially, metaproteomics was mainly used to assess the “expressed” metabolism and physiology of microbial community members.
Research Article | Host-Microbe BiologyEvaluating Metagenomic Prediction of the Metaproteome in a 4.5-Year Study of a Patient with Crohn's DiseaseA majority of current microbiome research relies heavily on DNA analysis. However, as the field moves toward understanding the microbial functions related to healthy and disease states, it is critical to evaluate how changes in DNA relate to changes in proteins, which are functional units of the genome. This study tracked the abundance of genes and proteins as they fluctuated during various inflammatory states in a 4.5-year study of a...
Research Article | Applied and Environmental ScienceNovel Syntrophic Populations Dominate an Ammonia-Tolerant Methanogenic MicrobiomeThe microbial production of methane or “biogas” is an attractive renewable energy technology that can recycle organic waste into biofuel. Biogas reactors operating with protein-rich substrates such as household municipal or agricultural wastes have significant industrial and societal value; however, they are highly unstable and frequently collapse due to the accumulation of ammonia. We report the discovery of a novel uncultured...
