摘要：
Production of carotenoid by Rhodotorula gracilis was highest at 26 mg/g dry weight with a carbon/nitrogen (C/N) ratio in the medium of 10:1. This was 15 times higher than when the C/N ratio was 160:1. With this high C/N ratio, the yeast produced up to 55% lipid compared only 20% lipid with the low C/N ratio. Both carotenoid and lipid production were non-growth associated.
