Treatment with benzyl-penicillin are effective. Mutagenesis breeding of benzyl penicillin strain 青霉素治疗有效,未发现不良反应。青霉素产生菌的诱变育种
Penicillin G potassium salt(ⅰ) was reacted with p-nitro benzyl bromide to produce the 4-nitrobenzyl ester of penicillin G acid(ⅱ). 以青霉素G钾盐Ⅰ为原料,与对硝基溴化苄反应生成青霉素G的对硝基苄酯Ⅱ。
Benzyl penicillin potassium and other twenty-four antibiotic drugs were recognized using neural networks. 运用神经网络识别青霉素钾等24种抗生素药物的红外光谱。
This experiment filtrates the benzyl penicillin strain with high yield by mutagenesis the benzyl penicillin strain No. 232 which available and used for the manufacture. 本试验通过用化学诱变剂对现有青霉素生产菌株232~进行诱变育种,筛选高产菌株。
