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 G8 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 6, G.lucidum 8 and G.lucidum 10 showed the highest lignin-degrading enzymes activity.  相似文献

利用筛选到的25个特异引物对蝴蝶兰不同花色品种作RAPD分析，确定了12个品种间的遗传距离；并根据Neighbor—joining遗传距离矩阵构建系统聚类文件，将该12个品种分为两个家族：第一家族中包含基色为白色的花色品种，花蕊颜色略有不同；第二家族为具有条纹的花色品种。品种间遗传距离最大为0．7832，最小为0．1034。  相似文献
