摘要: Mutant 32, derived from Rhodotorula glutinis NCIM 3353 produced 76-fold more beta-carotene than the parent strain. In growth medium prepared in seawater, total carotenoid content and dry cell mass was 86 mg/l 16 g/l, respectively, as compared to 70 12 g/l obtained with a distilled water. A 2-fold increase simultaneous 2.3-fold decrease torulene also observed. When grown seawater at pH 6.0, 83 +/- 5% carotenoids could be extracted cells without any mechanical disintegration.
