摘要
系统论述了当前有关乳酸菌发酵剂优良菌种的筛选方法与标准,具体包括:抗性菌株筛选、适宜蛋白水解力、乳糖水解力菌株的筛选、产粘菌株的筛选、产Nisin类细菌素菌株的筛选、柠檬酸利用阳性菌株与半乳糖利用阳性菌株、益生菌的筛选、乳酸菌溶原性及抗噬菌体菌株的筛选。同时,阐明了各优良性状的影响因素及最适表达条件,对生产发酵剂中优良菌株筛选及应用具有一定参考意义。
This paper system atically summarized the methods and standards of screening out lactic acid bacteria fine strain. It involved anti-stress characteristic, proper hydrolysis of protein and lactose, slime-producing strain, Nisin-liking strain, Gal * strain, citric acid strain, probiotic strain, lysogeny strain and anti-phage strain etc. Meanwhile, the various influencing factors on out standing biological character and proper condition to express the trait were clarified.
