凤尾菇酯酶同工酶及其氨基酸含量的变化

本试验研究了凤尾菇酯酶同工酶和氨基酸含量的变化,结果表明,不管栽培条件、采样部位和生长发育阶段如何,其酯酶同工酶酶谱基本相同,均有稳定的10条酶带,但它们的酶活性有所不同。在菌丝体生长阶段酶活性与生长天数有关。菌丝体生长4—20天时酶活性逐渐增强,尔后有所减弱。而子实体生长阶段从原基形成到菇体萎缩,酶活性则由强变弱。同时氨基酸含量也由高变低。

CHANGES OF ESTERASE ISOZYME AND AMINO ACIDS CONTENTS OF PLEUROTUS SAJOR-CAJU

Changing characteristics of the esterase isozyme and the amino acids contents of Pleurotus sajor-caju were investigated in the tests.The results show that the esterase isozyme patterns are basically the same,maintaining 10 bands stably in spite of the cultural conditions,the sampling positions and the growing or developing stages.But the esterase activity has difference and is correlated with the development.In the mycelial growing stage,the enzyme activity in- creases gradually with the growing days (4—20 days).Whereas in the fruitbody growth stage the enzyme activity decreases with the fruitbody's growing up from its young to its old (from the primordia to its withering),and the contents of amino acids decreases,too.
