| Description | Journal: Bioscience, Biotechnology, and Biochemistry Culture conditions were studied for l-isoleucine production from acetic acid. Acetate and ammonium concentration in culture liquid exerted a great influence on the fermentation, and optimum concentration was 2–5 g/liter and 2–3 g/liter respectively. To maintain these conditions throughout the culture, it was necessary to supply intermittently a small amount of feeding solution which consisted of ammonium acetate and acetic acid. Molecular ratio of the former to the latter was 0.175, and total concentration of acetic acid was 700 g/liter. Carbon dioxide showed an inhibitory influence on l-isoleucine production and adequate ventilation was necessary for satisfactory result. Maximum amount of l-isoleucine was 33.5 g/liter after 77-hr cultivation at 28°C and at pH 7.7. Production yield of l-isoleucine was 10% by weight from acetic acid. |
