羊肚菌菌丝营养生理特性的研究

Preliminary Study on Nutrition Physiological Ciiaracteristics of Morciiella Esculeuta Mycelia

从羊肚菌碳源、氮源、碳氮比、生长因子、微量元素等对Mx - 940 5菌株菌丝生长的影响。结果表明 ,淀粉 ,麦芽糖 ,葡萄糖 ,果糖 ,蔗糖是良好的碳源 ;半胱氨酸、天冬氨酸、天冬酰胺、亚硝酸钠、尿素为理想的氮源。 1～ 5mg/kg赤霉素 (GA)、6 -苄基嘌呤 (KT)能促进菌丝生长 ;Zn、Cu、Se等微量元素对羊肚菌生长影响最大 ;Mo、Ni、Pb、A1均不同程度地促进菌丝生长。Cd、Ti、Ag对菌丝生长完全抑制 ,Zn +Mn +Cu ,Zn +Mn、Zn +Mn +Mo。

The effects of carbon nitrogen sources,various growth factor and trace elements tested on mycelia growth of single ascospore strain Mx-9405 of M.esculeuta are reported in this paper.The organismsgrew well on starch,maltose,fructose,glucose and Sucrose.As nitrogen sources,cysteine,aspartic acid,asparagine,uren,soudium nitrite and sodium nitrogen were favorabie.The beneficial effect on growth of Morchella mycelia of the addition of 1-5mg/Kg GA and KT was suggested in this paper.Influence of trace elements on growth of the fungus was also discussed.
