美味牛肝菌菌丝体的营养特性

摘要

This study aimed to investigate the nutritional characteristics of Boletus edulis mycelium. The results showed that the optimal carbon source was glucose;the optimal nitrogen source was peptone; the optimal inorganic salt was KH2PO4;the optimal vitamin was VB1. The optimal medium, in which B. edulis mycelium in-cubated at 28 ℃ and pH 5.5 exhibited the strongest growth vigor and the rapidest growth rate, contained 3.0% glucose, 0.20% peptone, 0.60% KH2PO4, 0.20% Mg-SO4·7H2O and 0.000 50% VB1.%研究了美味牛肝菌菌丝体的营养特性。结果表明，美味牛肝菌生长的最适碳源是葡萄糖，最适氮源是蛋白胨，最适无机盐是KH2PO4和KH2PO4，最适维生素是 VB1；最适培养基为：3.0％葡萄糖、0.20％蛋白胨、0.60%KH2PO4、0.20% MgSO4·7H2O和0.00050％ VB1；最适 pH为5.0，最适温度为28℃，此时菌丝体生长速度最快，长势最好。
