SM1 strain is provided to show resistance on gastric juice and bile acid and excellent absorption capability of cells in the intestines and inhibit the growth of pathogenic microorganisms, thereby being usefully used as a therapeutic and prophylactic composition of a diseases caused by the pathogenic microorganisms. A lactobacillus sp. SM1 strain inhibiting vibrio bacteria and pathogenic bacteria has mycological characteristics of a bacillus showing Gram-positiveness, uses glycerol, D-ribose, D-galactose, D-glucose, D-fructose, D-mannose, D-mannitol, N-acetylglucosamine, amygdalin, arbutin, esculin ferric citrate, salicin, D-delibiose, D-maltose, gentiobiose, potassium gluconate, and potassium 2-ketogluconate as carbon sources and is deposited as a deposition no. KCTC 11043BP. A probiotics or a feed additive comprises the lactobacillus sp. SM1 strain or a culture supernatant thereof. A composition for treating and preventing diseases caused by pathogenic microorganisms comprises the lactobacillus sp. SM1 strain or the culture supernatant thereof or the probiotics as an effective ingredient.
Abstract:
PURPOSE: A Leuconostoc lactis EG001-derived sucrose phosphorylase is provided to convert sugar and to enhance safety and efficiency of ingredients. CONSTITUTION: A sucrose phosphorylase has an amino acid of sequence number 1. A gene encoding the sucrose phosphorylase is denoted by base sequence 2. The gene is derived from Leuconostoc lactis EG001. A recombinant microorganism is obtained by transforming a microorganism with a recombinant vector containing the gene. The sucrose phosphorylase is obtained by culturing the recombinant microorganism to obtain sucrose phosphorylase, and a step of collecting sucrose phosphorylase.
Abstract:
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(+).

Abstract:
PURPOSE: A method for preparing ascorbic acid 2-glucosdie with enhanced stability thorugh glycosylation of L-ascorbic acid is provided. CONSTITUTION: A method for preparing ascorbic acid 2-glucoside using glucansucrase comprises: a step of mixing L-ascorbic acid and bisaccahride with glucansucrase for glycosylation at 25-35°C and pH 4.5-6; and a step of collecting ascorbic acid 2-glucoside. The glucansucrase is denoted by sequence number 1 and is derived from Leuconostoc lactis EG001.
Abstract:
PURPOSE: A Ranunculus kazusensis Makino water extract having an excellent antibacterial activity without harm to human body is provided. CONSTITUTION: A Ranunculus kazusensis Makino water extract has an antibacterial activity to pathogenic microorganism. The pathogenic microorganism is Aeromonas salmonicida or Candida albicans. The Ranunculus kazusensis Makino water extract is isolated at 55-65°C. The extract contains water soluble aromatic compound. A method for extracting the extract having antibacterial activity comprises: a step of freeze-drying and pulverizing Ranunculus kazusensis Makino plant; a step of performing hot-extraction at 55-65°C for one to three hours; and a step of centrifuging to obtain supernatant.
