【摘要】 對本實驗室保藏的4個姬松茸品種進行了菌絲發酵,以酪蛋白、PNPP和ABTS為底物測定了菌絲體細胞內的蛋白酶、磷酸酶和漆酶的活性。數據結果顯示,被測定的4個姬松茸品種均具有磷酸酶的活性,其中姬松茸(巴西)的活性最高為48.1 U·g-1;蛋白酶和漆酶活性的檢測中發現,只有姬松茸7號和姬松茸11號具有活性,其中姬松茸7號具有較高的蛋白酶活性(95.2 U·g-)1,姬松茸11號具有較高的漆酶活性(58.6 U·g-)1。姬松茸7號和姬松茸11號同時具有3種酶的活性,可以作為深加工的優勢材料。

【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.
