一种利用乙酰微小杆菌处理废弃虾蟹壳提取甲壳素的方法
摘要：
本发明公开了一种利用乙酰微小杆菌处理废弃虾蟹壳提取甲壳素的方法，属于生物化工技术领域。利用乙酰微小杆菌对预处理后的废弃虾蟹壳进行发酵处理提取甲壳素控制发酵温度为30-40℃，发酵液pH为5.5-7.5，并通过振荡、搅拌或通气方式提供溶氧环境，发酵周期为10-16d；发酵结束后虾蟹壳的蛋白脱除率达93％以上，矿物质脱除率达90％以上。
摘要（英）：

The invention discloses a method for extracting chitin by treating waste shrimp and crab shells with exiguobacterium acetylicum and belongs to the technical field of biochemical engineering. Carryingout fermentation treatment on the pretreated waste shrimp and crab shells by using exiguobacterium acetylicum to extract chitin; wherein the fermentation temperature is controlled to be 30-40 DEG C, the pH value of the fermentation liquid is 5.5-7.5, a dissolved oxygen environment is provided in an oscillating, stirring or ventilating manner, and the fermentation period is 10-16 days; after fermentation is finished, the protein removal rate of the shrimp and crab shells reaches 93% or above, and the mineral substance removal rate reaches 90% or above.
