Abstract:
A new lactobacillus sp. KCTC 8458P (I) isolated from swine feces has the following (A) growth pH 1, (B) resistant to swine stomach juice for 100 min., (C) resistant to 5% bile acid, (D) growth at 7-45 deg.C, (E) amygdaline-unusable, and (F) arabinose- fermentable. The lyophilized material of resuspension of cell concen tration of (I) in defatted milk and glutamate sol. is useful for food additive and/or feed additives.
Abstract:
PURPOSE: Nocardioides nitrophenolicus as novel microorganism Nocardioides genus separated from wastewater is used as wastewater or sewage treatment by dissolving para-nitrophenol and phenol each or simultaneously without secondary pollution problem of environment. CONSTITUTION: Novel species Nocardioides nitrophenolicus purify wastewater or sewage polluted with para-nitrophenol and phenol as harmful material to affect fatal to human body and destroy ecological cycles and microorganism used to purify sewage and wastewater with harmful affection for stable natural environment generated as by-product in industrial working process or after without rising secondary pollution problem of environment through bioanalysis process using microorganism.
Abstract:
PURPOSE: A microorganism Klebsiella sp. producing pullulanase and a method for producing maltosyl beta-cyclodextrin using the same are provided, thereby the maltosyl beta-cyclodextrin can be effectively and cheaply produced. CONSTITUTION: The microorganism Klebsiella sp. 192 isolated from the soil can produce pullulanase which hydrolyzes the alpha-1,6-glucosidic bond of pullulan and converts into maltotriose. The method for producing maltosyl beta-cyclodextrin comprises the steps of: purifying pullulanase from Klebsiella sp. 192; reacting an enzyme solution containing the purified pullulanase, 500 to 700 mg/ml of maltose and 80 to 150 mg/ml of beta-cyclodextrin at an appropriate temperature of about 45 to 55 deg. C and pH 4.0 to 5.0; and separating the reacting materials by subjecting the solution to chromatography.
Abstract:
PURPOSE: A thermophilic cyclodextrin(CD) biosynthase and a method for producing the enzyme from Paenibacillus sp. are provided, which can biosynthesize alpha-CD, beta-CD and gamma-CD and cyclodextrin(CD) can be effectively used in medicines, cosmetics and foods. CONSTITUTION: The thermophilic cyclodextrin(CD) biosynthase is derived from a novel microorganism Paenibacillus sp. 324 strain(KCTC 0364BP), has 75,000 dalton of molecular weight, and shows its activity at pH 6.0 to 9.0 and 50 to 70 deg. C, in which cyclodextrin(CD) can seizure organic materials from starch because it has a hydrophobic region in its center. The thermophilic cyclodextrin(CD) biosynthase is produced by incubating Paenibacillus sp. 324 strain(KCTC 0364BP) in a medium containing 1 to 2% of starch, 3 to 7% of CSL and 0.5 to 1.5% of Na2CO3 at 35 to 40 deg. C.
