Esterase Isozyme Analysis of 14 Strains of Ganoderma / 微生物学通报

Antagonism, esterase isozyme ployacrylamide gel electrophoretic (EST-PAGE) and cluster analysis was used in the study of 14 strains of Ganoderma. The results showed that there were 18 bands of EST with different Rf. Cluster analysis at 50% similarity level showed that all strains could be clustered into five groups, the first included Xian zhi, Da xian 823, Nan han, Yuan zhi 6, Tian zhi, Han zhi; the second included Chi zhi 10, Chi zhi 12, Chi zhi, Ri ben hong zhi; the third included Zi zhi, Hei zhi; the fourth included Xue zhi; the fifth included Bai zhi. And this result was similar to the result of antagonism and morphological characters. Because of its stablity, the technique of EST can be used for identification of Gamoderma.
