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＆#183;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0.000 50%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。
