| 摘 要： | 首先分析了Ti鱼与四角哈两种低值海洋蛋白资源的营养成分，然后利用两株高产蛋白酶菌株通过液体发酵制备的蛋白酶制剂对两种蛋白资源进行了酶解，经过比较酶解率和肽含量，表明对于四角蛤，菌株SM98013产生的碱性蛋白酶和SM98011产生的中性蛋白酶都可高效酶解；而对Ti鱼，菌株SM98013产生的碱性蛋白酶的酶解效率较高。文中对海洋低值蛋白资源的高值化利用的途径进行了讨论。

| Abstract: | The contents of the nutritional component in the two kinds of low-value marine proteins were analyzed and hydrolyzed by the neutral and alkaline proteases produced by liquid fermentation with the strains of Bacillus subtilis SM98011 and B. subtilis SM98013, respectively. It was showed that the Mactra veneri formis Deshayes could be effectively hydrolyzed by both neutral and alkaline proteases, otherwise, the Engranlis japonicus was hydrolyzed more effectively by alkaline protease from B. subtilis SM98013 than neutral protease from B. subtilis SM98013. The application possibility of this high-valued marine protein was also discussed. |
