结合战备及农村基层检验室的需要,我们试用两种简易方法制备干燥培养基: 一、琼脂吸收法(适用于制备固体培养基),先将琼脂切成细片,置80℃烘箱中干燥2小时后研成粉末。取1:2牛肉浸液3,000毫升,蛋白胨30克,氯化钠15克,琼脂粉末45克。按常法制备普通肉汤培养基,调整至PH7.6,滤纸滤清后,先用直火浓缩至原体积五分之 Combine with war preparation and rural grass-roots inspection laboratory needs, we try two kinds of simple methods to prepare drying medium: First, the agar absorption method (for the preparation of solid medium), first agar cut into thin slices, set at 80 ℃ oven drying 2 After hours into a powder. Take 1: 2 beef extract 3,000 ml, peptone 30 grams, 15 grams of sodium chloride, agar powder 45 grams. Prepare the ordinary broth by the usual method, adjust to PH7.6, filter paper, first straight fire concentrated to the original volume of one-fifth
