【摘要】 <正> 关于青霉素酰化酶的研究,国内外报道的大多是大肠杆菌、青霉菌和克柔氏柠檬酸菌等。本文报道环状芽孢杆菌15(Bacillius cirulans No.15)产生青霉素酰化酶的初步研究。 环状芽孢杆菌15是四川制药厂从土壤中分离获得。斜面培养基:淀粉2％,蛋白胨0.6％,酵母膏0.3％,牛肉膏0.3％、琼脂2％;pH7.2～7.4,接种后37℃培养三天。种更多还原

【Abstract】 In this paper, a strain of Bacillus circulans NO. 15 isolated from soil was reported. The penicillin acylase can catalyze the phenyl glycine and 6-aminopenicillanic acid to produce a certain antibiotic which is different to ampicillin.更多还原
