Isolation of Chromosomal and Plasmid DNA from Bifidobacteria.

Rapid and efficient protocols aimed at the isolation and purification of DNA for the purpose of downstream applications, such as cloning, PCR, Southern blotting, or sequencing, are essential for genetic, biochemical, and molecular biological analyses of a given bacterium. The protocols herein presented provide a robust and efficient method for the isolation of chromosomal and plasmid DNA from Bifidobacterium strains by organic extraction. The methods are simple, and the yield, purity, and quality of the DNA are adequate to perform various downstream applications including next-generation sequencing.
