摘要: 本实验以紫甘薯为原料,采用液体深层发酵技术,应用响应面法优化了红曲霉液态发酵培养基。结果表明,以紫甘薯淀粉为碳源时,红曲霉发酵产红曲色素的二次多项数学模型具有显著性(p=0.0103),决定系数为0.947。由模型解逆矩阵得到:在紫甘薯淀粉、蛋白胨和L-谷氨酸钠浓度分别为12.63%、1.14%和0.35%时,红曲色素产量可达177.009U/ml。

Abstract: Purple sweet potato starch was taken as raw material for cultivation and the culture medium of Monascus with liquid fermentation were optimized by response surface methodology (RMS). The results indicated that the second-order polynomial mathematic model of Monascus pigments production yield by Monascus is significant (p=0.0103) and the determination R2 is 0.947. The predicted Monascus pigments production yield by Monascus is 177.009 U/ml when the contents of purple sweet potato starch, tryptone and the L-glutamine natrium are 12.63%, 1.14% and 0.35%, respectively.
