羊肚菌氨基酸含量变化及酯酶同工酶研究

本文对羊肚菌氨基酸含量及酯酶同工酶进行了研究，结果表明不同生长时期菌丝体的氨基酸含量变化较大，在4一10天内逐渐升高，15天达到高峰，尔后又有所降低。与此同时酯酶同工酶活性亦呈现相应的变化规律，由此可推测羊肚菌菌丝体生长过程中酯酶同工酶活性跟氨基酸代谢之间存在一定相关性。同工酶分析还发现不同子实体菌株及同一子实体不同单孢菌株间的酯酶同工酶谱基本相同，子实体与菌丝体均具有稳定的9条酶带。

CHANGES OF AMINO ACID CONTENTS AND STUDYOF ESTERASE ISOZYME OF MORCHELLAESCULENTA

Changes of the amino acid contents and the esterase isozyme of Morchella esculenta were investigated. The results show that the esterase isozyme patterns are basically the same, maintaining 9 bands stably in the mycelium growing stage. But the esterase isozyme activity has great difference and may be correlated with the metabolism of amino acid. The enzyme activity increase gradually with the growing days (4-15days).
