Abstract: Methods for prophylaxis or treatment of sepsis in a subject are provided comprising administering to the subject a therapeutically effective dose of multiple deletion strain bacteria.

Abstract: Provided herein is a nucleic acid comprising a mutant lac operator operably linked to a gene of interest, a host cell comprising the nucleic acid, and a method of using the host cell to express the gene of interest. Also provided is a recA-mediated cloning method.

Abstract: The present invention relates to cloning target nucleic acids using phage packaging mechanisms. Packaging initiation sites may be introduced into the target DNA. Components of a phage packaging system may be combined with the target DNA to package the DNA into phage capsids. The packaged DNA may be used to create a library of target nucleic acids, or it may be sequenced.

Abstract: An endonuclease which recognizes a specific nucleotide sequence, a gene coding for the endonuclease, a recombinant vector comprising the gene, a host cell comprising the vector, a process for producing the endonuclease, and methods of using the endonuclease are described.

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. 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: The present invention provides a bacterium having a genome that is genetically engineered to be at least 2 to about 20% 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.
