摘要:
The present invention relates to a microorganism having L-tryptophan productivity and a method for producing L-tryptophan using the same. More precisely, the present invention relates to the recombinant E. coli strain CJ600 (KCCM 10812P) having tryptophan productivity produced from the mutant form (KFCC 10066) of E. coli having L-phenylalanine productivity, wherein tryptophan auxotrophy is released, L-phenylalanine biosynthesis is blocked but tryptophan productivity is enhanced by reinforcing the gene involved in tryptophan biosynthesis, and a method of producing L-tryptophan using the same.

摘要:
The present invention relates to avirulent Salmonella gallinarum variants by inactivating virulence gene clusters of Salmonella gallinarum (SG), a main pathogen of avian salmonellosis, and various uses thereof notably in the production of Salmonella-specific lytic bacteriophages, pharmaceutical compositions and feed additives.
摘要:
The present invention relates to a novel bacteriophage, more particularly, a bacteriophage that has a specific bactericidal activity against Fowl Typhoid causing Salmonella Gallinarum (SG) and Pullorum disease-causing Salmonella Pullorum (SP). Further, the present invention relates to a composition for the prevention or treatment of infectious diseases caused by Salmonella Gallinarum or Salmonella Pullorum, comprising the bacteriophage as an active ingredient. Furthermore, the present invention relates to feed and drinking water for poultry, sanitizers and cleaners, comprising the bacteriophage as an active ingredient.

摘要:
The present invention relates to a putrescine-producing microorganism and a method for producing putrescine using the same. To be more specific, the present invention is directed to a microorganism given the ability to produce putrescine which is generated by blocking a biosynthetic pathway from ornithine to arginine, increasing the intracellular level of glutamate, enhancing the biosynthetic pathway of ornithine from glutamate, and introducing extracellular ornithine decarboxylase; and a method for producing putrescine by using the microorganism.
