固态发酵植物药提取残渣生产饲料蛋白工艺条件

摘要

Solid-state fermentation of extractive residue of Chinese herbs which comes from a traditional Chi-nese medicine plant to produce feeding-protein by the mixed fermentation was studied and the technique parame-ters in solid-state fermentation process was optimized with the aid of orthogonal experiments based on analyzing the component of the extractive residue of Chinese herbs. The results indicated that the optimum technique param-eters in the fermentation process are as below: cultivate temperature is 30℃, inoculated quantity is 15%(W/W), moisture content is 65% and cultivate time is 60h when the proportion of Yeast stain is 2∶1 (Candida utilis:En-domycopsis fibuligera) and 40g residue,35g corn steep liquor,8g corn flour, 15g wheat bran and 2g urea were chosen to make up of fermentation medium. Under the optimum fermentation condition, the content of crude pro-tein in fermentation product could be reach 29.98%. Producing feeding protein from extractive residue of Chinese herbs by fermentation is feasible.%以某制药厂双黄连制剂生产过程中产生的废弃药渣作为研究对象，在对药渣成份进行了全分析的基础上，利用正交实验法研究了混菌固态发酵植物药提取残渣生产饲料蛋白工艺参数的不同，对发酵产物蛋白含量的影响。结果表明：以40g药渣，35g玉米浆，8g玉米面，15g麸皮，2g尿素组成固态发酵培养基，产朊假丝酵母与扣囊拟内孢霉的菌种配比为2∶1时，最佳发酵条件为：发酵温度30℃，接种量15%，含水量65%，培养时间60h。在最佳发酵条件下，发酵产物的粗蛋白含量可达29.98%。以废弃药渣为主要原料发酵生产蛋白饲料是切实可行的。
