Diversity and community pattern of sulfate-reducing

Nov 11, 2018Among the gut microbiota, sulfate-reducing bacteria (SRB) is a kind of hydrogen-utilizing functional bacteria that plays an important role in intestinal hydrogen and sulfur metabolism. However, information is lacking regarding diversity and community structure of SRB in the gut of piglets. Middle cecum contents were collected from 6 Yorkshire and 6 Meishan piglets at postnatal days (PND) 14

Populations of Methanogenic Bacteria in a Georgia Salt

Abstract. Methanogens represented about 0.5% of the total bacteria in sediments from a Georgia salt marsh in which Spartina alterniflora is the predominant vegetation. The population of methanogens was composed of at least two groups of nearly equal size.

Methanogen Wikipedia

The final step of H 2 /CO 2 methanogenic involves methyl-coenzyme M reductase and two coenzymes N-7 mercaptoheptanoylthreonine phosphate (HS-HTP) and coenzyme F 430. HS-HTP donates electrons to methyl-coenzyme M allowing the formation of methane and mixed disulfide of HS-CoM. F 430, on the other hand, serves as a prosthetic group to the reductase.
