Microbial Biotechnology, Volume 18, Issue 3, March 2025.Metagenomic analysis of three thermophilic species was performed to identify key species for stable biogas production at high free ammonia levels (> 0.7 g/L). Potential acetogens and syntrophic acetate‐oxidising bacteria (SAOB) were recovered by looking for genes of the Wood–Ljungdahl pathway and glycine synthase reductase pathway.

Studies on the Corrinoids and Porphyrins in Streptomycetes
Agricultural and Biological Chemistry, 1968 A corrinoid, formed predominantly in the cells of Streptomyces olivaceus 605 grown aerobically on a glucose-lactose medium, was identical with 5,6-dimethylbenzimidazolyl-cobamide coenzyme (DBC coenzyme) by paper chromatography, paper ionophoresis, absorption spectrophotometry, assay of the coenzyme activity in diol dehydratase system and other tests ...

Vitamin B12: prevention of human beings from lethal diseases and its food application
Journal of the Science of Food and Agriculture, Volume 105, Issue 1, Page 10-18, 15 January 2025.Abstract Vitamin B12, a water‐soluble essential micronutrient, plays a pivotal role in numerous physiological processes in the human body. This review meticulously examines the structural complexity and the diverse mechanisms through which vitamin B12 exerts its preventive effects against a spectrum of health conditions, including pernicious anaemia ...

Trace elements induce predominance among methanogenic activity in anaerobic digestion
Frontiers in Microbiology, 2016 Trace elements play an essential role in all organisms due to their functions in enzyme complexes. In anaerobic digesters, control and supplementation of trace elements lead to stable and more efficient methane production processes while trace element ...

Gut microbial O-dealkylation of isoflavone derivatives by Blautia sp. MRG-PMF1
Applied Biological ChemistryThe anaerobic bacterium Blautia sp. MRG-PMF1 is known for its ability to biotransform aryl methyl ether and allyl aryl ether substrates via a cobalamin-dependent O-demethylase system. To investigate the substrate promiscuity of this corrinoid-dependent O-
