Abstract

The adaptation of lactic streptococci for growth with their homologous bacteriophage was studied through the addition of bacteriophage filtrate to skim milk medium inoculated with Streptococcus lactis or Streptococcus cremoris. Both S. lactis and S. cremoris attained their adaptability for growth with their homologous bacteriophage after 5 and 2 transferes, respectively, and did not lose it after a storage period of 30 days at 0 degree C.

摘要

通过向接种了乳酸链球菌或嗜热链球菌的脱脂乳培养基中添加噬菌体滤液，研究了乳酸链球菌对其同源噬菌体生长的适应性。乳酸链球菌和嗜热链球菌分别在5次和2次传代后获得了对其同源噬菌体生长的适应性，并且在0℃储存30天后没有丧失这种适应性。
