Some factors controlling the differentiation of sporangia and gemmae in an isolate of Achlya sp. were investigated by replacement culture technique. Factors in the replacement medium which affect differentiation were as follows: A) Calcium is required for the differentiation of both sporangia and gemmae. B) Calcium cannot be replaced by magnesium, potassium or sodium. C) Gemmae are induced when the replacement medium contains salt at 40 to 80 mm. D) The salt induction of gemmae is nonspecific, sodium, potassium, magnesium and calcium chlorides are equally effective.
采用置换培养技术研究了控制一种水霉属菌株中孢子囊和芽孢分化的一些因素。置换培养基中影响分化的因素如下：A）孢子囊和芽孢的分化都需要钙。B）钙不能被镁、钾或钠替代。C）当置换培养基中盐浓度为40至80毫米时可诱导芽孢形成。D）芽孢的盐诱导是非特异性的，氯化钠、氯化钾、氯化镁和氯化钙的效果相同。
