Abstract

The ability to produce diplococcin (Dip+) was transferred by conjugation from Streptococcus cremoris 346 to two plasmid-free S. cremoris recipients at a high frequency (10(-1) per donor). Dip+ transconjugants from each mating gained a 54-megadalton plasmid. Spontaneous loss of this plasmid restored the Dip- phenotype.

摘要

产双球菌素（Dip+）的能力通过接合作用从嗜热链球菌346高频转移至两个无质粒的嗜热链球菌受体菌（每个供体菌的转移频率为10⁻¹）。每次交配产生的Dip+转接合子获得了一个54兆道尔顿的质粒。该质粒的自发丢失恢复了Dip-表型。
