Abstract

The bacteriophage Mu d1(Apr lac cts62 ) obtained from an Escherichia coli double lysogen carrying the defective Mu d1 phage and a Mu-P1 hybrid phage was utilized as a vector for phage mutagenesis in Erwinia carotovora subsp. carotovora. Among ampicillin-resistant transductants. 1.4% were auxotrophs. The synthesis of beta-galactosidase was derepressed upon starvation for histidine in two different his-lac fusion strains.

摘要

从携带缺陷型Mu d1噬菌体和Mu - P1杂交噬菌体的大肠杆菌双溶源菌中获得的噬菌体Mu d1(Apr lac cts62 )被用作胡萝卜软腐欧文氏菌胡萝卜软腐亚种噬菌体诱变的载体。在氨苄青霉素抗性转导子中,1.4%是营养缺陷型。在两种不同的组氨酸 - 乳糖融合菌株中,组氨酸饥饿时β - 半乳糖苷酶的合成被去阻遏。
