摘要
采用固体培养和液体培养方法研究了鸡菌的培养特性以及培养基、pH值、酵母膏对其菌丝生长的影响。结果表明:鸡菌在普通固体培养基中生长缓慢,菌落较小,在培养后期,菌株间存在3种明显的菌落类型即“菌丝型”、“孢子型”、“中间型”,产孢量和形态也有较大差异。在液体培养条件下鸡菌的生长较快,培养基、pH值、酵母膏浓度对液体菌丝生长存在很大影响。各供试菌株在液体摇床培养中的最佳培养条件基本一致:即最适pH值为4.5;酵母膏最佳质量浓度为0.2 g/dL;理想培养基为PSDYB。
In this manuscript, the cultural characteristics of Termitomyces spp were compared in solid and submerged culture. Furthermore., the nourishment and environmental conditions for Termitomyces spp growth were determined. Compared with that of the submerged culture, a very slow growth rate was observed on solid medium. The optimum culture conditions for Termitomyces spp growth in flask were follows： pH 4.7; yeast extract 0.2%; medium PSDYB.
