Abstract
The production of pantothenic acid and thiamine by Azotobacter vinelandii was studied in a chemically defined medium and a dialysed soil medium amended with different amounts of carbohydrate and NH sup+inf4 . Pantothenic acid and thiamine were produced in large amounts in the culture medium containing 2.0–5.0% glucose and 0.1–0.3% NH4Cl. The results showed that the liberation of these vitamins was increased under adiazotrophic conditions and with an excess of C source.
