Abstract

Abstract: Addition of oxygen-vectors（n-hexane, n-dodecane, hexadecane）to fermentation medium was recognized as a method of enhancing oxygen transfer and promoting lycopene yield by Rhodotorula fermentation. n-dodecane as an oxygen-vector is the best in three kinds of liquid alkane. Experimental results show that the biomass of Rhodotorula attained 16.49 g/L and the yield of lycopene biosynthetic reached 42.32 mg/L by adding 4% n-dodecane in the 0 h, which was 26.2% and 50.17% higher than the control group, respectively.

Key words: Rhodotorula, lycopene, liquid alkane, oxygen-vectors, oxygen transfer
