Abstract

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