富硒金针菇菌丝多糖的初步研究

A Preliminary Study on the Polysaccharide Contents in Se Accumulated Flammulina velutipes mycelia

就不同菌种、不同菌株、不同硒浓度、不同培养天数以及菌种在含硒斜面上驯化与否等因素对富硒金针菇菌丝多糖含量的影响进行了研究。结果表明 ,采用固体菌种、液体菌种和孢子菌种培养的金针菇 0 0 1号富硒菌丝多糖含量均高于对照 ;金针菇 12号菌丝多糖含量最高 ;一定浓度的Na2 SeO3可提高菌丝多糖含量 ;菌种在含硒斜面驯化可提高菌丝多糖含量 ;富硒菌丝以培养 12d时多糖含量最高。

The effect of different spawns, strains, Se concentrations, culture days and domesticated or not in Se containing slant on the polysaccharide contents in Se-accumulated Flammulina velutipes mycelia was studied. And the result showed that the Se accumulated mycelial polysaccaride contents in F. velutipes 001 strain inoculated with solid, liquid or spore spawns were all higher than that of the control, that the mycelial polysaccharide contents of F. velutipes 12 strain were the highest, and that definite concentration of Na 2SeO 3 could raise mycelial polysaccharide contents, strains domesticated in Se containing slant could increase the contents of mycelial polysaccharide and the polysaccharide contents of Se accumulated mycelia cultured for 12d were the highest.
