研究了微生物从维生素B12类似物中生成CO的过程，因为CO是其他一些含金属的环状四吡咯的分解产物。CO在羟钴胺与蜡状芽孢杆菌或α-溶血性缓症链球菌有氧孵育过程中产生。该反应类似于这些微生物的血红素催化，因为CO不是在厌氧条件下形成的，也不是由S的非溶血菌株形成的。缓解。氰钴胺素部分抑制羟钴胺素的CO形成。
Microbial CO formation from vitamin B12analogues was investigated, since CO is a catabolic product of some other metal-containing cyclic tetrapyrroles. CO was evolved during aerobic incubation of hydroxocobalamin with eitherBacillus cereusor α-hemolyticStreptococcus mitis. The reaction resembles heme catabolism by these microbes in that CO was not formed under anaerobic conditions nor by a nonhemolytic strain ofS. mitis. Cyanocobalamin partially inhibited CO formation from hydroxocobalamin.
