摘要
将不同产地的6个云芝菌株进行液体培养,通过多糖产量、多糖质量和蛋白质质量等指标,从中选出了3个优良菌株.采用高效液相凝胶过滤色谱法(HPGFC)测定这3个菌株提取物云芝胞内多糖的相对分子质量,并加以比较.根据实验的结果,确认菌株LS为液体发酵的首选菌株.
Three Coriolus versicolor strains with higher polysaccharide yield in liquid culture were selected from six Coriolus versicolor strains from different regions. Protein and polysaeeharide contents in their myeelium were then compared. Their molecular weights were also determined and compared with high performance gel filter chromatography. From the experimental results, Coriolus versicolor strain LS was considered to be the optimum strain for liquid culture.
