摘　　要：本文对红曲霉变异株Ａ６进行了产红曲色素发酵条件试验，发现在以６％饴糖为碳源，以０３％ＮａＮＯ３为氮源的培养基，初始ｐＨ４０～４５，接种量为１５％时产色素浓度最高。同时，考察了整个发酵过程中ｐＨ，残糖量与色素生成浓度的关系，认为发酵周期拟控制在８０～８５ｈｒ为宜。The fermentative conditions for Monascus pigments of Strain A 6 were examined in this paper The result of the experiment indicated that there was higher pigment concentration in the midium of 6% maltose,0.3% sodium nitrate,under the initial pH 4.0-5.0 and inoculum size.Another result of the experiment was that certain concentration sugar was fed to the fermentative flask at some time in a fermentive cycle can also increase the pigment quantity
