Soil microbial community response to corrinoids is shaped by a natural reservoir of vitamin B12. [PDF]
ISME JSoil microbial communities perform critical ecosystem services through the collective metabolic activities of numerous individual organisms. Most microbes use corrinoids, a structurally diverse family of cofactors related to vitamin B12.

The prospects for the use of vitamin B12 derivatives in pharmacology
Фармакоэкономика, 2023 Background. The structure of corrin tetrapyrrole macrocycles (compounds similar in structure to vitamin B12) is a kind of universal chemical template for targeted drug delivery, and the development of chemical sensors and antidotes.Objective ...

Corrinoids in anaerobic bacteria [PDF]
FEMS Microbiology Letters, 1990 C1-metabolizing bacteria were analyzed for their corrinoids. The autotrophic phototrophe Chloroflexus aurantiacus contains predominantly the light-sensitive coenzyme B12. The corrinoid could be teh prostethic group of a methylmalonyl-CoA mutase, which is involved in the CO2 fixing reaction sequence from proplonyl-CoA to succinyl CoA.

Identification of specific corrinoids reveals corrinoid modification in dechlorinating microbial communities [PDF]
Environmental Microbiology, 2014 Summary Cobalamin and other corrinoids are essential cofactors for many organisms. The majority of microbes with corrinoid‐dependent enzymes do not produce corrinoids de novo , and instead must acquire corrinoids produced by other organisms in their environment. However, the

Characterization of Vitamin B12 Compounds in Fermented Poultry Manure Fertilizers
Agriculture, 2021 (1) Background: Currently, no data are available on the vitamin B12 content of an organic fertilizer product, viz. fermented poultry manure, or whether the organic fertilizer product contains vitamin B12 or inactive corrinoids (or both).
