摘　　要：探讨了恒定pH值对粘质沙雷氏菌ZSG7发酵产灵菌红素的影响。结果表明,当发酵系统pH值恒定为7时,粘质沙雷氏菌生长速度最快,灵菌红素产生速度最快且产量最高(0.3033g·L-1),比不调pH值的灵菌红素最高产量0.2296g·L-1高出32.1%。The effect of constant pH value on prodigiosin producing by Serratia marcescens ZSG7 was discussed.The results showed that,when the pH value was kept 7,ZSG7 grew the fastest,generation speed of prodigiosin was the fastest,and the maximum production reached 0.3033g·L-1,which was 32.1% higher than the maximum 0.2296g·L-1 under the unregulated pH value.
