Abstract

The present invention discloses that a bacterium having a genome that is genetically engineered to be at least 10% smaller than the genome of its native parent strain has better transformation competence. Specific E. coli strains, having significantly reduced genome sizes, are disclosed which are highly transformation competent. A medium and methodology is taught which enables transformation efficiencies to be increased further.
