摘　　要：考察了三孢酸结构类似物α-紫罗酮、β-紫罗酮和脱落酸对番茄红素生产菌Blakeslea trispora的生长和番茄红素合成的影响。结果表明α-紫罗酮、β-紫罗酮和脱落酸对Blakeslea trispora菌体生长影响不大,但都能明显刺激番茄红素的合成。在发酵培养2d后加入α-紫罗酮、β-紫罗酮和脱落酸,番茄红素的产量最高。其中脱落酸的添加对番茄红素产量影响最为显著,在发酵2d后添加脱落酸9.36×10-3mmol/L,番茄红素产量达到549mg/L,比对照(382mg/L)提高了44%。The effects of added β-ionone, β-ionone and abscisic acid （ABA） on the growth and lycopene biosynthesis of Blakeslea trispora have been investigated. The results showed that α-ionone, β-ionone and abscisic acid all have no effect on the growth of Blakeslea trispora but do promote the accumulation of lycopene. The lycopene production was improved when α-ionone, β-ionone and abscisic acid were added to the culture after 2 days. Of the three compounds, ABA had the most obvious effects on the production of lycopene. The lycopene production reached 549 mg/L when ABA （with a concentration of 9.36 × 10^- 3 mmol/L） was added after 2 days, which was 44% higher than that of the control （382 mg/L）.
