| 摘 要： | 对本实验室保藏的4个姬松茸品种进行了菌丝发酵,以酪蛋白、PNPP和ABTS为底物测定了菌丝体细胞内的蛋白酶、磷酸酶和漆酶的活性。数据结果显示,被测定的4个姬松茸品种均具有磷酸酶的活性,其中姬松茸(巴西)的活性最高为48.1 U·g-1;蛋白酶和漆酶活性的检测中发现,只有姬松茸7号和姬松茸11号具有活性,其中姬松茸7号具有较高的蛋白酶活性(95.2 U·g-)1,姬松茸11号具有较高的漆酶活性(58.6 U·g-)1。姬松茸7号和姬松茸11号同时具有3种酶的活性,可以作为深加工的优势材料。

| Abstract: | Four strains of Agaricus blazei were chosed,which were available in our lab.The activities of proteinase,phosphatase and laccase were studied.The results showed that all of the tested strains exhibited the phosphatase activity,and the phos-phatase activity of Agaricus blazei was the highest of 48.1 U·g-1.It was found that Agaricus blazei No.7 had the highest pro-teinase activity of 95.2 U·g-1 and Agaricus blazei No.11 had the highest laccase activity of 58.6 U·g-1.The other two strains were devoid of proteinase and laccase activities.In all,Agaricus blazei No.7 and Agaricus blazei No.11 can be considered as advanced strains in process engineering. |
