STUDY OF SOME FACTORS INFLUENCING BIODEGRADATION OF ISOPROPYLBENZENE BY RHODOCOCCUS ERYTHROPOLIS

摘要

THE PRESENT STUDY EXAMINES THE EFFECT OF VARIOUS FACTORS ON THE BIODEGRADATION OF IPB BY RHODOCOCCUS ERYTHROPOLYS. BY THE IMPLEMENTED PLAN OF PLACKETT AND BURMAN, A POSITIVE EFFECT OF IRON, NEUTRAL pH AND ETHANOL ON THE BIODEGRADATION COULD BE DEMONSTRATED. COMPLEMENTARY EXPERIMENTS IN A BIOREACTOR SHOW THAT ETHANOL, USED AS COSUBSTRATE IN BUFFERED MEDIUM, ALLOWS CELL GROWTH WHILE OPTIMIZING BIODEGRADATION OF IPB.
