Genetically Modified Pseudomonas Strains With Enhanced Biocontrol Activity

View page
US Patent:
59553480, Sep 21, 1999
Filed:
Nov 25, 1997
Appl. No.:
8/977306
Inventors:
James Madison Ligon - Apex NC
Nancy R. Torkewitz - Hurdle Mills NC
Dwight Steven Hill - Cary NC
Thomas Deane Gaffney - Chapel Hill NC
Jill Michelle Stafford - Cary NC
Assignee:
Novartis AG - Basle
International Classification:
C12N 120
C12N 1500
A01N 6300
C12P 2106
US Classification:
43525234
Abstract:
Strains of Pseudomonas have been genetically engineered to have enhanced biocontrol properties. The strains of the invention are particularly effective against plant pathogenic fungi such as species of Rhizoctonia and Pythium, because the strains produce enhanced amounts of antifungal metabolites such as pyrrolnitrin that are active against these fungal pathogens. Both the genetically modified biocontrol strains and the antifungal metabolites can be used as active agents for biocontrol compositions.

US Patent:
56100442, Mar 11, 1997
Filed:
Nov 29, 1994
Appl. No.:
8/346331
Inventors:
Stephen T. Lam - Raleigh NC
Nancy R. Torkewitz - Hurdle Mills NC
Chandra S. Nautiyal - Sainte-Foy,
Patrice Dion - Sainte-Foy,
International Classification:
C12N 120
C12N 121
C12N 1509
C12N 1556
US Classification:
4351723
Abstract:
The present invention relates to a method for enhancing colonization of desired microorganisms in a localized environment comprising introducing into said localized environment a genetically engineered microorganism comprising a gene comprising a DNA sequence coding for one or more substrate utilizing protein, wherein said substrate utilizing protein confers a competitive effective ability to utilize a substrate by a microorganism in which it is genetically engineered, as well as the isolated genes and the genetically engineered microorganisms of such a method.
