摘要
只有活性乳酸菌群≥106个/mL的乳酸菌饮料,才能真正起到增强机体免疫功能、延缓机体衰老等保健作用,检测活性乳酸菌的含量成为判断产品质量好坏的重要手段。该文通过大量试验,对国标中乳酸菌检验方法中菌落特征及菌体形态的文字描述作了进一步细化、具体化的实物图像补充,从抽象的文字描述转变成更清晰、形象的图像说明,为准确计数乳酸菌总数提供了依据。
Yoghurt beverage would enhance immunity and delay senescence of body only when the number of active lactic acid bacteria was above 106 cfu/ml. The detection of active lactic acid bacteria was an important way to judge the quality of yoghurt beverage, and the colony characteristics and morphology was the key for colony counting. More detailed and idiographic descriptions of colony characteristics and morphology were showed by pictures, which were more clear and visual than nonfigurative descriptions in words. And this method provided the basis for accurately counting of lactic acid bacteria.
