Abstract:
PURPOSE: An oral composition for preventing and treating dental caries due to breeding of the oral bacteria and periodontal diseases is provided to enhance antibacterial activity for Streptococcus mutants and/or Fusobacterium nucleatum. CONSTITUTION: An oral composition for preventing and treating dental caries due to breeding of the oral bacteria and periodontal diseases contains Bilberry, Vaccinium myrtillus L. which are uniformly dispersed inside an aqueous film substrate. The composition is manufactured into film, dentifrice, oral cavity cleaning solution, ointment, spray, dressing solution, coating material, dental floss, or preodontal pack. The Bilberry is uniformly dispersed inside the aqueous-soluble film material at the concentration of 0.2-0.5 mg / ml. The composition displays the antibacterial activity for Streptococcus mutans and/or Fusobacterium nucleatum.
Abstract:
PURPOSE: An oral composition for preventing and treating periodontal diseases by bacterial proliferation in the oral cavity is provided to ensure antibacterial activity against Porphyromonas gingivalis and/or Prevotella intermedia. CONSTITUTION: A composition for preventing and treating periodontal diseases by proliferation of Prevotella gingivalis contains polysorbate, sorbitan esters of fatty acids, or extract of Biberry or Scutellariae radix inside a soluble film substrate. The polysorbate is evenly dispersed in a concentration of 0.7x10^-4 -0.04 mg/ml inside the soluble film substrate. The sorbitan fatty acid ester is evenly dispersed in a concentration of 0.15-0.03 mg/ml inside a soluble film substrate.

PURPOSE: A Leuconostoc Lactis EG001-derived novel glucansucrase which are isolated from Kimchi lactobacillus is provided to use in foods and medicinal and pharmaceutical industries. CONSTITUTION: A glucansucrase is denoted by amino acid of sequence number 1. The optimal pH concentration and temperature are pH 4.5-6 and 25-35°C, respectively. A gene encoding the glucansucrase is denoted by base sequence of sequence number 2. The gene is derived from Leuconostoc Lactis EG001. A recombinant microorganism which is able to produce glucansucrase is obtained by transforming a host microorganism with a recombinant vector having the gene. The recombinant microorganism is E.coli BL21(DE3)/pET22b(+).

PURPOSE: A Paenibacillus sp. EA001 strain-derived novel-2-dioxyribose 5-phosphate aldolase(DERA) is provided to manufacture various physiologically active ingredients through enzymetic method. CONSTITUTION: A 2-dioxyribose-5-phosphate aldolase has an amino acid sequence of sequence number 1. The aldolase is obtained from Paenibacillus sp. EA001 strain. A 2- deoxyribose 5- phosphate aldolase gene has a nucleotide gene of sequence number 2. A recombinant vector contains the 2- deoxyribose 5- phosphate aldolase gene.
Abstract:
The present invention relates to a method for producing recombinant 2-deoxyribose 5-phosphate aldolase (DERA) derived from Haemophilus influenzae Rd KW20. More specifically, the present invention relates to a method for producing recombinant DERA and a method for producing lactol using the recombinant DERA, wherein a recombinant microorganism having a recombinant DERA productivity is cultured, and a gene coding the recombinant DERA having a base sequence of sequence number 1 or a recombinant vector containing the gene is induced in a host cell. The recombinant DERA of the present invention has lower substrate inhibition and more excellent activities for acete aldehyde than existing enzymes. A functional group (2-carbon unit), such as an acetaldehyde derivative, having two carbons is continuously condensed in an acceptor molecule so that lactol which is an intermediate product during a statin synthesizing process can be synthesized. Accordingly, the recombinant DERA can be variously applied to chemical processes requiring carbon polymerization.
