Abstract:

The effect of simultaneously added nicotine and hydrogen peroxide on lycopene accumulation during Rhodotorula fermentation was explored. Amounts and addition time point of nicotine and hydrogen peroxide significantly affected the biosynthesis of lycopene during fermentation. A maximum lycopene content of 86.88 mg/L was achieved after Rhodotorula fermentation for 36 h with additions of 2.5 mL/L nicotine and 1.6 mL/L hydrogen peroxide, which was 21.2 times higher than that without additions of nicotine and hydrogen peroxide.

Key words: Rhodotorula, lycopene, effector, nicotine, hydrogen peroxide
