摘要
为探究阿魏菌丝生长的最适合条件,研究不同营养条件和不同培养条件下阿魏菌丝的生长速度。结果表明:最适宜阿魏菌丝生长的碳源是麦芽糖,氮源是蛋白胨。对阿魏菌丝生长有促进效果的是磷酸二氢钾和硫酸镁,而硫酸亚铁有抑制作用。温度为25℃时,菌丝生长最快。阿魏菌丝在微碱性培养基环境中长势较好,其最适宜pH为8.0。
In order to explore the suitable condition for growth of Pleurotus ferulae Lanzvi. mycelium, the growth rate of Pleurotus ferulae Lanzvi. mycelium was studied under different nutrient and culture conditions. The results showed that the optimum carbon source for mycelium growth was maltose, nitrogen source was peptone. Potassium dihydrogen phosphate and magnesium sulfate could promote mycelium growth,and ferrous sulfate had inhibitory effect. At 25℃, the hyphae growed the fastest. The alkaline medium environment was suitable for the mycelium growth,the most appropriate pH was 8.0.
