Biodegradation of the fatty acylamino acids by Fusarium culmorum, measured in terms of the release of radioactive aspartate and lysine, occurred maximally at pH 6.5 and pH 7.0, respectively in 10 day cultures. Thirty-six percent and twenty-four percent of the total radioactivity recovered were in released aspartate and lysine, respectivley at 30°C. Twenty degrees (C) was the minimum temperature for biodegradation of these compounds by F. culmorum. Greater degradation was observed at 15°C and 30°C. The data suggest the activity of hydrolytic isoenzymes, with optima at different pH's and temperatures, operating in the biodegradation process.
