【摘要】 研究了以小米为原料液态发酵生产红曲色素的发酵培养基组配及相关工艺参数的选择。结果表明,优化的发酵培养基组成为:小米粉11.0%,麦芽粉2.0%,谷氨酸钠0.4%及少量无机盐;摇瓶发酵工艺条件为:装液量75ml/500ml:三角瓶或45ml/250ml三角瓶,接种量7%～8%(V/V),发酵液起始pH5.0,发酵温度32℃,发酵时间80h,成熟醪液红曲色价127个单位。更多还原

【Abstract】 It described the choice of fermentation media and conditions of monascus pigment production by sub-merged fermentation of millet.The o ptimized media were chosen as millet11.0%,malt 2.0%,monosodium glutamate 0.4%and some inorganic sa lts.The fermentation parameters we re obtained:pH5.0in the beginning,filling 45ml mediumin 250ml flask or75ml in 500ml flask,seeding 7%～8%,fermentation temperature and the time 80hours.The color value reached above 127Uin the liquid.更多还原
