Parallel Chromosomal Stacking Of Traits In Bacteria
US Patent:
7252942, Aug 7, 2007
Filed:
Dec 12, 2003
Appl. No.:
10/734778
Inventors:
Pierre E. Rouviere - Wilmington DE, US
Wonchul Suh - Hockessin DE, US
Wonchul Suh - Hockessin DE, US
Assignee:
E.I. du Pont de Nemours and Company - Wilmington DE
International Classification:
C12Q 1/68
US Classification:
435 6, 435471, 435472
Abstract:
The invention describes a method for the stacking of traits in a recombination proficient host using a phage transduction system. The method makes use of a nucleic acid integration cassette that has homology to a specific site on a host chromosome for the insertion of genetic elements and the stacking of traits. Repetition of the method results in the stacking of traits on a single genetic element.
Method To Increase Hydrophobic Compound Titer In A Recombinant Microorganism
US Patent:

International Classification:
C12P 1/00
C12N 1/00
C12N 1/00
US Classification:
435 41, 4352523, 43525411, 4352572, 4353201
Abstract:
Expression of at least one plant oleosin gene in a microbial cell engineered to produce hydrophobic/lipophilic compounds significantly increases the overall titer of the compound. The hydrophobic nature of the oleosin core is believed to increase the microbial host cell's internal storage capacity for any hydrophobic/lipophilic compound. The method is exemplified using a bacterial host cell engineered to produce significant amount of various carotenoids.

Abstract:
An enteric bacterial strain was engineered to over-produce L-tyrosine using a one-step method. The pheA-tyrA chromosomal region of the bacterial genome was replaced with an engineered chromosomal segment, resulting in inactivation of the pheA coding region and strong expression of the tyrA coding region, resulting in high levels of L-tyrosine production.

Assignee:
Butamax(TM) Advanced Biofuels LLC - Wilmington DE
International Classification:
C12P 7/58
US Classification:
435137, 4352542, 435160
Abstract:
Yeast strains were engineered that have increased activity of heterologous proteins that require binding of an Fe—S cluster for their activity. The yeast strains have reduced activity of an endogenous Fe—S protein. Activities of heterologous fungal or plant 2Fe-2S dihydroxy-acid dehydratases and Fe—S propanediol dehydratase reactivase were increased for increased production of products made using biosynthetic pathways including these enzymes, such as valine, isoleucine, leucine, pantothenic acid (vitamin B5), isobutanol, 2-butanone and 2-butanol.

Abstract:
Lactic acid bacterial (LAB) cells were modified such that they have a specific activity of dihydroxy-acid dehydratase enzyme activity that is increased to about 0. 1 μmol minmg. LAB cells with even higher activities of 0. 2 to 0. 6 μmol minmgof DHAD activity were obtained. These modified cells may be used to produce isobutanol when additional isobutanol biosynthetic pathway enzymes are expressed.
Method For Chromosomal Engineering
US Patent:
2004020, Oct 21, 2004
Filed:
Dec 12, 2003
Appl. No.:
10/734936
Inventors:
Wonchul Suh - Hockessin DE, US
International Classification:
C12N015/74
C12N001/21
C12N001/21
US Classification:
435/488000, 435/252300
Abstract:
A method is provided for the integration of foreign genetic elements into a bacterial chromosome without the need of a cloning step. The method relies on the presence of the -Red recombinase system in a recombination proficient bacterial host. At least two linear recombination elements or constructs are co-transformed into the recombination proficient host which are assembled in the correction orientation in the bacterial chromosome by homologous recombination. Selectable markers used for the selection of transformants are later excised by the action of a site-specific recombination.
Increasing Carotenoid Production In Bacteria Via Chromosomal Integration
US Patent:
2004021, Nov 4, 2004
Filed:
Dec 12, 2003

International Classification:

C12N001/21
C12N001/21
US Classification:
435/067000, 435/252330
Abstract:
The present invention relates to carotenoid overproducing bacteria The genes of the isoprenoid pathway in the bacterial hosts of the invention have been engineered such that certain genes are either up-regulated or down regulated resulting in the production of carotenoid compounds at a higher level than is found in the un-modified host. Genes that may be up-regulated include the dxs, idi, ispB, lytB and ygbBP genes. Additionally it has been found that a partial disruption of the yjeR gene has the effect of enhancing carotenoid production.
