RESUMO

To develop an efficient method for the production of coenzyme A (CoA), optimal conditions for its formation from pantothenic acid, cysteine, and adenine were studied. A number of microorganisms were screened for production of CoA. Strains belonging to the genera Sarcina, Bacillus, Microbacterium, Micrococcus, and Serratia accumulated CoA. Among these, Sarcina lutea was selected as the best organism, and the culture conditions for the production of CoA were investigated with this organism. Under optimal conditions, 600 μg of CoA per ml was accumulated in the culture broth. CoA was readily isolated in high purity by the use of charcoal, diethylaminoethyl-cellulose, Sephadex G-25, and Dowex-50. Yields of isolated CoA were over 33% from culture broth.
