Abstract
|
|
|
|
To investigate oleic acid biodegradation, 47 fungal strains were tested with modified Czapek Dox broth media containing oleic acid, and their biodegradative activities were assayed by measuring the release of [^14C]CO_2 from the ^14C- labeled oleic acid. After 72 h of cultivation, Aspergillus flavus, Aspergillus ochraceus, and Alternaria species metabolized approximately 25% to 35% of the supplied oleic acid. The relationship between the fungal degradation of oleic acid and the fungal growth was also examined using 7 strains of Aspergillus niger. A. niger YMC 0100 and YMC 0322 degraded about 26% of the oleic acid after 72 h, while their germination ratios were more than 30%.
