Wirkung von Ölen und Fettsäuren auf Wachstum und Enzymbildung bei Thermoactinomyees vulgaris. V. Untersuchungen zur Metabolisierung des Öles

The splitting of vegetable and animal oils used as antifoam agents and the metabolization of fatty acids released were analysed during fermentation of T. vulgaris in a 30 l jar fermenter. During cultivation time of 22 hours the oil amount decreased by 60 to 70%. The metabolization of fatty acids is 50 to 90% of the starting level depending on the kind of acid. The eventual effect of the fatty acids released from antifoam oils on the protease production is discussed.
