摘　　要：为优化雁鹅菌菌丝的培养条件,以菌丝生长速度为评价指标,通过单因素试验分别确定雁鹅菌菌丝生长培养基的最佳碳源、氮源以及无机盐,并通过比较不同的营养元素浓度对雁鹅菌菌丝生长速度的影响,确定各营养元素的最佳添加区间,后续采用正交试验法优化雁鹅菌菌丝生长培养基中各营养元素的组合。结果表明,最佳碳源为可溶性淀粉,最佳氮源为胰蛋白胨,最佳无机盐为氯化钙。雁鹅菌菌丝生长培养基的最优组合为可溶性淀粉浓度5 g·L^(-1),胰蛋白胨浓度3 g·L^(-1),培养基中氯化钙浓度1.00 g·L^(-1)。In order to optimize the cultivation conditions of the mycelium of Lactarius deliciosus,the mycelial growth rate was used as an evaluation index.The optimal carbon source,nitrogen source,and inorganic salt for the mycelial growth medium of Lactarius deliciosus were determined through single factor experiments.By comparing the effects of different nutrient element concentrations on the mycelial growth rate of Lactarius deliciosus,the optimal range for adding each nutrient element was determined.Subsequently,the orthogonal experimental method was used to optimize the combination of various nutrient elements in the mycelial growth medium of Lactarius deliciosus.The results indicate that the optimal carbon source is soluble starch,the optimal nitrogen source is tryptone,and the optimal inorganic salt is calcium chloride.The optimal combination of mycelial growth medium for wild goose fungus is soluble starch concentration of 5 g·L-1,tryptone concentration of 3 g·L-1,and calcium chloride concentration of 1.00 g·L^(-1) in the medium.
