摘　　要：采用不同方法对银耳多糖产生菌 (银耳酵母状分生孢子 )进行保藏研究。结果表明 ,不同保藏方法对银耳菌种的存活力及产糖活性存在着不同程度的影响 ,以牛奶为防护剂 ,-Six preservation methods for storaging Tremella polysaccharose producing strains were studied. The results showed that there were different viabilities and sacchrogenic activities affected by different preservation methods. The paraffin oil method could be used for long term preservation, not for long term sustaining saccharogenic activity. The freezing method with skimmed milk as cryoprotectant at -30 °C could maintain not only survival potential but also saccharogenic activity.
