Abstract
The biosynthesis of biotin-vitamers from pelargonic acid by Pseudomonas sp. strain 393 was investigated. The main product of biotin-vitamers from pelargonic acid was desthiobiotin. The addition of streptomycin or l-alanine enhanced accumulation of desthiobiotin in culture fluid. Propionic, pimelic and azelaic acids were identified as main metabolites from pelargonic acid. When propionic acid was incubated with resting cells, pelargonic and azelaic acids were formed. The biosynthetic pathway of pelargonic acid to pimelic acid was also studied.
