Effect of the low molecular modulator on lycopene fermentation

Abstract

Fermentation is one of potential methods for producing lycopene industrially by Blakeslea trispora .The effect ofthe modulator on lycopene fermentation was investigated. The results showed that triton-X100 had little effect on fermentation,but span-20 and β-ionone could enhance the productivity of lycopene significantly. The content of lycopene in the mediumreached 98.6mg/L by adding 1g/L span-20. The content was 3 times as much of the control experiments.
