Karst produced in different locality was determinated by the UV\|spectrophotometry. The contents of total nucleosides in sporophore of \%G. lucidum \%from Guangxi of China and Viet Nam were 0.33%and 0.34%, the higher contents from Taiwan, Jiangsu and Guangdong were 0.40%~0.46% and lower contents from Yunnan were 0.16%~0.21%. The research proposed a criterion on the quality of \%G. lucidum \%and a brief discussion about its utilization and development. The TLC identification of uracil, adenine, adenosine and uridine in sporophore of \%G. lucidum \%was carried out. The methodological study indicated that the method was simple, reliable and specific.展开更多
文摘分别利用紫外线和超高压诱变漆酶产生菌灵芝(Ganoderma.lucidum Karst),发现超高压的诱变幅度较大.经初步筛选和发酵,获得了2株具有较大应用潜力的漆酶超高压突变株G1502和G2001,前者漆酶活力比出发菌株提高了2.83倍,发酵时间缩短了1 d;后者漆酶活力提高了0.89倍,发酵时间缩短了3 d.
