Abstract:
A method for increasing activity of an enzyme for a multi-glycosyl hydrolase single enzyme Cel44C is provided to obtain multi-functional singly enzyme mutant enzymes with significantly increased enzyme activity of cellulase, xylanase, lichenase or mannanase compared to a wild-type Cel44C by removing a C-terminal of the Cel44C molecular-biologically, thereby being very useful for a paper manufacturing industry, and an environment industry and an agricultural industry for producing organic farm. A method for increasing activity of cellulase, xylanase, lichenase, and mannanase of a wild-type Cel44C comprises the steps of: (a) inserting an artificial termination codon into a C-terminal gene sequence of a wild-type multi-functional single enzyme Cel44C(NCBI access no. DQ367923) to construct a primer; (b) performing a polymerase chain reaction using the primer and cloning it into a cloning vector to prepare a mutant; (c) transforming the mutant; (d) investigating the plant cell wall lytic enzyme activity of the transformed mutant; and (e) measuring each enzymatic activity of the transformed mutant and the wild-type Cel44C through a reducing sugar quantitation technique, wherein the primer consists of sequences described in SEQ ID : NOs. 3 to 6.
Abstract:
A method of separating indole acetic acid from Pseudomonas strain is provided to promote rearing of mushroom, to reduce considerably a cost for producing oil and a labor cost and to be used in order to develop mushroom culture medium for the low cost and to culture other edible mushrooms besides the pine mushroom, gardening and vegetables. An indole acetic acid is separated from Pseudomonas sp. 7014 KACC 91277P strain culture fluid or an ethylacetate layer extract of the culture fluid. A method of stimulating a growth of the edible mushrooms comprises a step of mixing the indole acetic acid and an amino acid at a rate of 1:1(v/v). The ethylacetate layer extract has an activity of stimulating a growth of the Pseudomonas sp. 7014 KACC 91277P strain.
Abstract:
A method of rapidly producing fermented soybeans and soy sauce is provided to obtain fermented soybeans and soy sauce with a high content of surfactin exhibiting cytotoxicity against breast cancer cells and intestinal cancer. Bacillus pumilus HY1 strains(KACC 91280P) having excellent surfactin producing capacity are isolated from Korean traditional soy sauce. Surfactin and 5 types of isomers are identified from the Bacillus pumilus HY1 strains. Soy sauce is rapidly prepared by using the Bacillus pumilus HY1 strains as a starter. The soy sauce using Bacillus pumilus HY1 strains as a starter is fermented about 15 days faster than untreated control group. The surfactin content of soy sauce 45 days after fermentation exhibits 0.008mg/L in case the Bacillus pumilus HY1 strains are inoculated, as compared with 0.005mg/L in case the Bacillus pumilus HY1 strains are not inoculated.
Abstract:
A sequence of an esterase coding gene(est5S) is provided to be isolated from ruminant stomach bacteria, which is not be cultured by a conventional technique. An esterase is provided to be a novel esterase not belonging to a conventional fat hydrolysis group and show significant effect on metal ions and organic solvent, thereby being useful for food industry, environment industry, agricultural industry and medicinal industry. A novel esterase gene hydrolyzing fat includes a sequence described as SEQ ID : NO. 1 derived from ruminant stomach bacteria identified from cow rumen metagenome. An esterase hydrolyzing the fat includes an amino acid sequence described as SEQ ID : NO. 2 derived from the ruminant stomach bacteria identified from cow rumen metagenome.
