Abstract: 建立了一种渗透处理微球菌细胞的方法,得到的透性化细胞可多批使用并能长时间保持胞内酶的活力,极大地提高了单位菌体的利用率,降低了成本,为海藻糖实现工业化开辟了新的思路。实验结果表明:菌悬液用5%(v/v)甲苯处理40min,得到的菌体即为透性化细胞,再以10%淀粉液化液为底物进行海藻糖转化实验,转化率可达70%;该透性化细胞至少可连续进行6批酶反应(12h/批),酶活基本保持稳定。
A permeabilization method of Micrococcus cells has been established. The obtained penneabilized cells could be used for several batches and in the mean time the intracellular enzymes still keep high activity. This method will undoubtedly increase the productivity of the cells and cut down the cost; therefore, it will be a promising way in the treha-lose industrialization. The experiment shows: after being treated with 5% (v/v) methylbenzene for 40min, the cells in suspension were converted into permeabilized cells, then the latter acted on 10% liquefied starch to produce trehaloae, the conversion ratio could reach 70%. The penneabilized cells could be used at least for 6 batchs (12h per batch) and the intracellular enzyme activity kept steady.
