保藏方法和期限对肠膜明串珠菌发酵收率的影响

Effects on fermentation yields of Leuconostoc mesenteroides by preservation methods and times

通过对肠膜明串珠菌菌种进行冷冻管、液体管和斜面试管等保藏方法的比较,结果表明:冻干菌种保藏方法最优,保存期可达24年以上;但必须先优化菌种,选择发酵收率高和稳定性好的菌株制备冻干菌种,以供工业生产所需。

In this paper, comparisons of Leuconostoc mesenteroides with three different method including freeze-drying preservation, slant preservation and liquid wax preservation method had been studied. Results showed that freeze-drying preservation was the best preservation method and its retention period reached more than 24 years, But must optimize strains to select high fermentational-yielding and higher stability strains at the same time of preparing of freeze-drying strains for industry production.
