MeSH headings : Anaerobiosis; Animals; Female; Gene Deletion; Gene Expression Profiling; Gene Expression Regulation, Bacterial; Metabolic Networks and Pathways / genetics; Mice; Mice, Inbred C57BL; Microarray Analysis; Regulon; Repressor Proteins / genetics; Repressor Proteins / metabolism; Salmonella typhimurium / genetics; Salmonella typhimurium / growth & development; Salmonella typhimurium / metabolism

TL;DR: The results demonstrated that in S. Typhimurium, ArcA serves as a transcriptional regulator coordinating cellular metabolism, flagella biosynthesis, and motility, and a set of 120 genes whose regulation was shared with the anaerobic redox regulator, Fnr. (via Semantic Scholar)

MeSH headings : Biofuels; Biotechnology / methods; Butanols / toxicity; Clostridium beijerinckii / drug effects; Clostridium beijerinckii / growth & development; Clostridium beijerinckii / metabolism; Culture Media / chemistry; Fermentation; Gene Expression Profiling; Gene Expression Regulation, Bacterial; Glucose / metabolism; Stress, Physiological; Xylose / metabolism

TL;DR: Results indicated that C. beijerinckii SA-1 was able to coferment hexose/pentose sugar mixtures in the absence of a glucose repression effect, and the analysis suggests that the solvent and acid resistance mechanisms found in this strain are differentially regulated compared to strain NRRL B-527.

MeSH headings : Anaerobiosis; Animals; Bacterial Proteins / genetics; Bacterial Proteins / metabolism; Cells, Cultured; DNA-Binding Proteins / genetics; DNA-Binding Proteins / metabolism; Escherichia coli Proteins / genetics; Gene Expression Profiling; Gene Expression Regulation, Bacterial; Humans; Iron-Sulfur Proteins / genetics; Iron-Sulfur Proteins / metabolism; Macrophages, Peritoneal / microbiology; Mice; Mice, Inbred C57BL; Molecular Sequence Data; Mutation; Oligonucleotide Array Sequence Analysis; Salmonella Infections / microbiology; Salmonella Infections / pathology; Salmonella typhimurium / genetics; Salmonella typhimurium / growth & development; Salmonella typhimurium / metabolism; Salmonella typhimurium / pathogenicity; Transcription Factors / genetics; Transcription Factors / metabolism; Virulence

TL;DR: The role of FNR as a positive regulator of motility, flagellar biosynthesis, and pathogenesis was confirmed by showing that the isogenic fnr mutant is nonmotile, lacks flagella, is attenuated in mice, and does not survive inside macrophages. (via Semantic Scholar)
