Rapid plasmid DNA isolation from Lactococcus lactis using overnight cultures

  • Published:
Biotechnology Techniques

Abstract

A simple and quick method has been developed to isolate plasmid DNA from Lactococcus lactis using overnight or stationary-phase cultures which therefore eliminates the need for subculturing for generating log-phase cultures that are necessary with existing methods. The new method was effective in isolating plasmids, from 1.4 to 64 kb, from the three subspecies of Lactococcus lactis. The resultant DNA was of high yield and purity and therefore no additional purification steps were required for down-stream molecular procedures.
