Abstract

The fermentative properties of recombinants obtained after conjugation between E. coli K12 HfeC and S. flexneri la Lac Phe mutant were investigated. The recombinants showed the antigenic structure of S. flexneri but their biochemical characteristics differed from the properties typical for this genus. The recombinants were found to acquire the ability to ferment several carbohydrates not degraded by the S. flexneri recipient strain.

摘要

对大肠杆菌K12 HfeC与弗氏志贺菌1a Lac Phe突变体接合后获得的重组体的发酵特性进行了研究。重组体呈现出弗氏志贺菌的抗原结构,但其生化特性与该属的典型特性不同。发现重组体获得了发酵几种未被弗氏志贺菌受体菌株降解的碳水化合物的能力。
