The action of certain chemical mutagens such as N-nitroso methyl urea, N-nitroso ethyl urea, N-nitroso dimethyl urea and N-nitroso methyl biuret, as well as physical ones such as UV light on Escherichia coli producing penicillin acylase was studied. High mutagenic activity of N-nitroso methyl biuret with respect to this culture was shown.
研究了某些化学诱变剂（如N-亚硝基甲基脲、N-亚硝基乙基脲、N-亚硝基二甲基脲和N-亚硝基甲基缩二脲）以及物理诱变剂（如紫外线）对产青霉素酰化酶的大肠杆菌的作用。结果表明，N-亚硝基甲基缩二脲对该培养物具有高诱变活性。
