Draft Genome Sequences of Methanobrevibacter curvatus DSM11111, Methanobrevibacter cuticularis DSM11139, Methanobrevibacter filiformis DSM11501, and Methanobrevibacter oralis DSM7256
Here, the draft genome sequences of four different Methanobrevibacter species are presented. Three of the Methanobrevibacter species (M. curvatus, M. cuticularis, and M. filiformis) have been isolated from the termite hindgut, while M. oralis was isolated from human subgingival plaque.
متن کاملChildren Living near a Sanitary Landfill Have Increased Breath Methane and Methanobrevibacter smithii in Their Intestinal Microbiota
This study evaluated the breath CH4 excretion and concentration of M. smithii in intestinal microbiota of schoolchildren from 2 slums. One hundred and eleven children from a slum near a sanitary landfill, 35 children of a slum located away from the sanitary landfill, and 32 children from a high socioeconomic level school were included in the study. Real-time PCR was performed to quantify the M....
متن کاملGenomic and metabolic adaptations of Methanobrevibacter smithii to the human gut.
The human gut is home to trillions of microbes, thousands of bacterial phylotypes, as well as hydrogen-consuming methanogenic archaea. Studies in gnotobiotic mice indicate that Methanobrevibacter smithii, the dominant archaeon in the human gut ecosystem, affects the specificity and efficiency of bacterial digestion of dietary polysaccharides, thereby influencing host calorie harvest and adiposi...
متن کاملCharacteristics of a water-forming NADH oxidase from Methanobrevibacter smithii, an archaeon in the human gut
NADH oxidases (NOXs) catalysing the oxidation of NADH to yield NAD+ and H2O, H2O2, or both play an important role in protecting organisms from oxidative stress and maintaining the balance of NAD+/NADH. A gene encoding NOX was identified from Methanobrevibacter smithii (NOX-ms), the predominant archaeon in the human gut ecosystem. Subsequent analyses showed that it is an FAD-containing protein w...
متن کاملCharacterization of the ATP-Dependent Lon-Like Protease in Methanobrevibacter smithii.
The Lon protease is highly evolutionarily conserved. However, little is known about Lon in the context of gut microbial communities. A gene encoding a Lon-like protease (Lon-like-Ms) was identified and characterized from Methanobrevibacter smithii, the predominant archaeon in the human gut ecosystem. Phylogenetic and sequence analyses showed that Lon-like-Ms and its homologs are newly identifie...
