Plasmid DNA in Streptococcus cremoris Wg2: Influence of pH on Selection in Chemostats of a Variant Lacking a Protease Plasmid

Cleared lysates of a proteolytic (Prt(+)) strain and a naturally occurring non-proteolytic (Prt(−)) variant of Streptococcus cremoris Wg2 contain equal amounts of covalently closed circular plasmid DNA. An analysis of this plasmid DNA by agarose gel electrophoresis revealed the presence of at least...
