摘要:

研究烟碱、双氧水这两种效应物对红酵母发酵累积番茄红素的影响,发现其加入的量和加入的时间对累积量影响显著。结果表明,在红酵母发酵至36h 时,同时加入2.5mL/L 烟碱和1.6mL/L 双氧水(含30% 的过氧化氢),可使番茄红素得到大量的积累,达到86.88mg/L,是不加烟碱和双氧水时番茄红素产量4.10mg/L 的21.2 倍。

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
