白背木耳菌丝体生理特性的研究

本文对白背木耳深层培养条件等进行了研究并对菌丝体主要营养成分进行分析。白背木耳的适宜发酵条件为：pH为5，移种量为5％，种子周期5d（天），发酵周期4d。Zn 和赤霉素可以明显促进白背木耳深层发酵的产量。三十烷醇可明显提高菌丝体胞内多糖含量。白背木耳菌丝体富含18种氨基酸，总量为20．72g／100g干样。

Physiological Characters And Nutritive Couponents Analysis of Auricularia polytricha Mycelia

Auricularia polytricha is a kind of edible fungus with health effect and delicacy. In this paper, it is reported that submerged fermentation process and main nutritive components analysis of this strain are studied. The suitable cultare conditions are as follows: pH5, inoculate 5%, the seed period is five days and the cultural period is four days. The production of submerged fermentation process can be improved obviously by Zn and gibberellin. At the same time, TA can improve the mycelia polysaccharide content of the mycelia obviously. The results indicate that the mycelium contains 18 kinds of amino acids with a total dry weight as 20.72g/100g.
