作者应用选择性培养基从混合的细菌中分离绿脓杆菌.为寻找可抑制伴随细菌丛生长,而对绿脓杆菌无影响的药剂,作者选择了青霉素和ethonium.后者具有相当广泛的抗菌谱,且几乎不抑制绿脓杆菌的生长.较大剂量的青霉素对许多微生物有抑制作用,但绿脓杆菌能够产生青霉素酶,对其有耐受性,故在培养基中加入适量的青霉素可作为绿脓杆菌选择性生长的条件.培养基的制备 1升溶解的营养琼脂培养基中
The authors used selective media to isolate Pseudomonas aeruginosa from mixed bacteria. In an effort to find agents that have no effect on Pseudomonas aeruginosa that inhibit bacterial growth, the authors selected penicillins and ethonium, which has a broad antimicrobial spectrum , And almost does not inhibit the growth of Pseudomonas aeruginosa.More large doses of penicillin inhibition of many microorganisms, but Pseudomonas aeruginosa can produce penicillinase, its tolerance, so in the medium by adding the appropriate amount of penicillin can be used as Conditions for the selective growth of Pseudomonas aeruginosa Preparation of medium 1 liter of solubilized nutrient agar medium
