Abstract:
PURPOSE: A method for producing heavy chain dicarboxylic acids, carboxylic acids, and alcohols from long chain fatty acids is provided to produce a large amount of heavy chain dicarboxylic acids, carboxylic acids, and alcohols by enzyme reaction of a transformant which expresses Baeyer-Villiger monooxygenase (BVMO) and to safely and cheaply produce heavy chain dicarboxylic acids, carboxylic acids, and alcohols. CONSTITUTION: A transformant contains a gene encoding BVMO. BVMO is derived from Pseudomonas fluorescens, Pseudomonas putida, Pseudomonas veronii, Rhodococcus jostii, or Pseudomonas sp. strain HI-70. A method for producing heavy chain dicarboxylic acids, carboxylic acids, and alcohols from long chain fatty acids comprises the steps of: culturing the transformant in a medium containing the long chain fatty acids and obtaining a culture; and collecting heavy chain dicarboxylic acids and carboxylic acids or alcohols from the culture.

Abstract:
PURPOSE: A method for preparing 10-hydroxystearic acid is provided to prepare a large amount of 10-hydroxystearic acids and to be used as a starting material for synthesizing lactone. CONSTITUTION: An oleate hydratase used for producing 10-hydroxystearic acid is selected from sequence numbers 1-4. The enzyme is derived from Lysinibacillus fusiformis, Macrococcus caseolyticus, Propionibacterium acnes, and Stenotrophomonas maltophilia. A gene sequence encoding enzyme protein is selected from sequence numbers 5-8. A method for preparing the enzyme comprises: a step of preparing a recombinant expression vector containing a gene for the enzyme; a step of culturing a microorganism transformed with the recombinant expression vector; a step of inducing the expression of the gene; and a step of isolating and purifying the recombinant proteins.
Abstract:
The present invention relates to a pharmaceutical composition and a food composition for preventing or treating lung cancer, comprising Bifidobacterium probiotics or an extract thereof as an active ingredient. The pharmaceutical composition of the present invention can inhibit the proliferation of lung cancer cells and induce cell death of lung cancer cells, and thus may be widely used for the prevention or treatment of lung cancer.
Abstract:
PURPOSE: A method for preparing oxide using transformed Corynebacterium sp. is provided to remarkably enhance of oxide productivity. CONSTITUTION: An oxide is prepared by inducing oxidation using transformed Corynebacterium with a gene encoding oxidase. The Corynebacterium sp. is Corynebacterium glutamicum or Corynebacterium ammoniagenes. The oxidase is Baeyer-Villiger oxdiase. The Baeyer-Villiger oxidase is cyclohexanone monooxygenase. A substrate is cyclohexanone. The oxide is prepared by culturing transformed Corynebacterium sp. with cyclohexanone monooxygenase through fed batch culture.
