dc.description.abstract | When the concentration of the antibiotic cerulenin was increased up to 3.0 mg/Z in medium containing ethanol as a carbon source, the specific growth rate of Acinetobucter culcouceticus and the fatty acid content of the emulsan decreased from 0.179 h-l and 13.9% to 0.015 h-l and 3.4x, respectively. The emulsifying activity in medium containing cerulenin decreased with increasing cerulenin concentration. In the culture containing 3.0 mg/l cerulenin, fatty acid biosynthesis was inhibited. Various fatty acids were added to this inhibitory culture as a second carbon source to modify the fatty acid group in the emulsan. When an odd-numbered fatty acid was added, the resulting emulsan was found to have other odd-numbered fatty acids that were not present originally. Among the emulsan produced from even-numbered fatty acids, the emulsan produced from myristic acid ((214) contained the greatest amount of the same-numbered fatty acids. When the amount of supplemental my&tic acid was increased, the myristic acid content in the emulsan increased, but its emulsifying activity decreased. | en |
