实践证明,一个优良的菌种,长时间地使用某一种母种培养基继代(转管),很容易引起菌种的衰老,以至“退化”。若经常更换母种培养基成份,则能起延缓菌种衰老和防止菌种退化的作用。为了选择供经常更换使用的母种培养基配方,我们选配了9种母种培养基配方,对9个生产推广的食用菌菌种进行了优选试验(斜面培养)。试验表明,母种培养基Ⅰ和Ⅵ,对供试菌种中的多
Practice has proved that a good strain, prolonged use of a mother medium subculture (tube), it is easy to cause the aging of bacteria, and even “degenerate.” If you frequently change the mother’s medium components, you can delay the bacteria senescence and prevent the role of strain degradation. In order to select the formula of mother culture medium for replacement, we chose 9 kinds of mother culture medium formula, and tested and optimized nine kinds of mushroom strains (slant culture). Experiments show that the mother medium Ⅰ and Ⅵ, for the test strains more
