6-苄基腺嘌呤对平菇和香菇菌丝体4种胞外酶活性的影响

在马铃薯液体培养基中，通过活加不同剂量的6－苄基腺嘌呤（6－BA），测定了平菇和香菇菌丝体4种胞外酶活性的变化。结果表明，低浓度的外源6－BA对平菇、香菇菌丝体4种胞外酶活性都有促进作用，高浓度时则逐渐抑制酶活性。其中，培养液浓度为1．5mg/100mL时，它们扔包外粉酶（Amy）、羧甲基纤维素酶（CMC）、过氧化氢酶（CAT）的活性最高；而它们的胞外蛋白酶的最适浓度为0．5mg/100mL。

The Effect of 6-Benzyl Aminopurine on the Activities of Four Extracellular Enzymes in Plurotus ostreatus and Lentinula edodes Mycelium

Four extracellular enzyme activities in Pleurotus ostreatus and Lentinula edodes mycelium were determined by adding to different dosage additional 6 benzyl aminopurine (6 BA) in potato liquid medium. The results showed that low concentration of 6 BA promoted their activities and high concentration inhibited their activities. For Pleurotus ostreatus and Lentinula edodes, the optimum concentration of 6 BA to activate their extracellular amylase, carboxymenthel cellulase and catalase was the same which was 1 5 mg/100 mL culture solution. But, the optimum concentration for their extracellular protease was 0 5 mg/100 mL culture solution.
