Optimization of Fermentation Conditions for Blue Pigment Production by Bacterial Strain T2013

The fermentation conditions of Bacterial Strain T2013 were studied. The fermentation conditions of T2013 were investigated with single-factor experiment. In addition to, the fermentation conditions were optimized through the orthogonal test. The results showed the highest production of blue pigment was obtained on condition that fermentation time was 2d, the liquid volume was 50ml in the 250ml shake-flask, the inoculum volume was 2%, the initial value of pH was 7.6, fermentation temperature was 37°C and the speed was 150r/min.The fermentation conditions of Bacterial Strain T2013 were preliminarily determined,whichprovides a theoretical basis for the industrial production of blue pigment.
