灵芝属木质素降解高效菌株筛选

The diagnostic methods of extracelluar oxidase mat were used to select lignin-degrading enzymes producers among nineteen Ganoderma lucidum fungal strains.The results showed that the producing laccase activity of G.sp.var.Tianzhi was the highest,followed by that of G.lucidum 10 and G.lucidum 8.The producing lignin peroxidase activity of G.sp.var Tianzhi was the highes,and the producing Manganese peroxidase activity of G.sp.var yuanzhi 6 and G.lucidum G 8 were the highest,followed by that of the G.sp.var.Tianzhi and G.lucidum 10.It was found that G.sp.var Tianzhi,G.sp.var.Yuanzhi 6G.lucidum 8 and G.lucidum 10 showed the highest lignin-degrading enzymes activity.

蜂花粉、蜂蜜为基质灵芝液体发酵饮料的研制

目的以灵芝(菌种)、油菜蜂花粉(主要氮源)、油菜蜂蜜(主要碳源)三种传统保健食品作为原料,制备一种营养丰富的发酵型食用菌饮料,并解决蜂花粉深加工时破壁难的问题。方法将发酵液与柠檬酸、蔗糖和稳定剂进行调配,经抽滤、罐装、杀菌制得饮料成品,同时对发酵液中的营养成分和花粉破壁率及饮料中的各项指标进行检测。结果发酵饮料的最佳配方为:发酵液35%,蔗糖14%,柠檬酸0.26%,羧甲基纤维素钠(CMC)的添加量为0.15%。发酵液中多糖的含量为25.74 mg/m L,蛋白质的含量为0.79 mg/m L,花粉破壁率为72.94%。结论本研究制得的食用菌饮料,天然美味,营养丰富,符合国家的相关标准。
