Environmental MicrobiologyRoles of d-Lactate Dehydrogenases in the Anaerobic Growth of Shewanella oneidensis MR-1 on SugarsNADH-dependent LDHs are conserved among diverse organisms and contribute to NAD+ regeneration in lactic acid fermentation. However, this type of LDH is also present in nonfermentative bacteria, including members of the genus Shewanella, while their physiological roles in these bacteria remain unknown. Here, we show that LdhA (an NADH-dependent...
Microbial EcologyFeeding Rapidly Alters Microbiome Composition and Gene Transcription in the Clownfish GutDespite extensive study of intestinal microbiome diversity and the role of diet type in structuring gut microbial communities, we know very little about short-term changes in the intestinal microbiome as a result of feeding alone. Sampling microbiomes over a feeding cycle will allow us to differentiate opportunistic, feeding-responsive microbes from resident, potentially commensal members of the gut community. Also, since feeding has...
Food MicrobiologyThe MarR Family Regulator BmrR Is Involved in Bile Tolerance of Bifidobacterium longum BBMN68 via Controlling the Expression of an ABC TransporterBifidobacteria are natural inhabitants of the human intestinal tract. Some bifidobacterial strains are used as probiotics in fermented dairy production because of their health-promoting effects. Following consumption, bifidobacteria colonize the lower intestinal tract, where the concentrations of bile salts remain nearly 0.05% to 2.0%. Bile salts, as detergent-like antimicrobial compounds, can cause cellular membrane disruption, protein...
