摘要
利用硅胶、活性炭、中性氧化铝、乙醚、正丁醇、石油醚、丙酮等对红曲霉培养液进行脱色处理,脱色后的培养液进行凝乳实验,并与原液作比较。结果发现,活性炭脱色效果最好,但其脱色后凝乳力较小;硅胶脱色效果较好,且脱色后培养液的凝乳力也较高。通过实验确定最佳条件是:培养时间7d,硅胶脱色,培养液用量12%,凝乳温度50~55℃。
The cultivation liquid of Monascus Spp was decolorized by the use of the reagents such as silica gel, activated charcoal, neutral alumina, aether, butyl alcohol, petroleum ether and acetone. The cultivation liquid was tested for curding and compared with its original liquid. The results showed that the activated charcoal was the best in the decolorizing, but its curding strength decreased almost to zero. Considering the decolorizing effect and curding strength, silica gel is the better than any other reagent. The optimum conditions of decolorizing of the cultivation liquid was cultivation time 7d, silica gel decolorizing, cultivation liquid amount 12% and curding temperature 50~55℃.
