Abstract: Reduced genome strains of E. coli MG1 655 are described. In various embodiments, the strains have one or more of equal or improved growth rate, transformation efficiency, protein expression, DNA production, DNA yield and/or DNA quality compared to the parental strain and commercially available strains.

Abstract: The present invention provides a bacterium having a genome that is genetically engineered to be smaller than the genome of its native parent strain. A bacterium with a smaller genome can produce a commercial product more efficiently. The present invention also provides methods for deleting genes and other DNA sequences from a bacterial genome. The methods provide precise deletions and seldom introduces mutations to the genomic DNA sequences around the deletion sites. Thus, the methods can be used to generate a series of deletions in a bacterium without increasing the possibility of undesired homologous recombination within the genome. In addition, some of the methods provided by the present invention can also be used for replacing a region of a bacterial genome with a desired DNA sequence.

Abstract: A bacteria lacking genomic and non-genomic IS elements is provided. The bacteria may be more stable and useful for the production of amino acids, polypeptides, nucleic acids and other products.

Abstract: The present invention provides a bacterium having a genome that is genetically engineered to be at least 2 to 14% smaller than the genome of its native parent strain. A bacterium with a smaller genome can produce a commercial product more efficiently. The present invention also provides methods for deleting genes and other DNA sequences from a bacterial genome. The methods provide precise deletions and seldom introduces mutations to the genomic DNA sequences around the deletion sites.

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.
