In order to eliminate phenol in industrial wastes, a screening and isolation of phenolmetabolizing microbes have been attempted. A few strains of yeasts which could metabolize phenol actively were isolated from sewage or activated sludge. Taxonomical characteristics of these isolates were examined and two of the most active ones were identified as Rhodotorula glutinis var. glutinis and Candida tropicalis, respectively. In media containing phenol of 500 mg/ml, R. glutinis var. glutinis No. 692 and C. tropicalis No. 708 decomposed phenol completely by aerobic cultivation at 30 ℃ within 5 or 3 hr, respectively.Decomposition of phenol by the newly isolated strains was compared with that of the several taxonomically related authentic strains from type culture. It was found that the authentic strains of R. glutinis var. glutinis also showed significant ability to decompose phenol. In a culture which was successively fed with phenol to the maximum concentration of 500 mg/l at appropriate intervals, R. glutinis var. glutinis No. 692 and C. tropicalis No. 708 could give about 1 mg/ml and 2 mg/ml of cell yield by aerobic cultivation for 18 hr.
