| A bacterium that produce biopolymer was isolated from Gochujang, one of Korean traditional fermented foods, and identified as Bacillus licheniformis. The production of biopolymer was highest and 34mg/250ml, when the baterium was cultivated in condition of sucrose 6.0%, Yeast extract 0.1%, peptone 0.l%, NaCl 3.0%, and pH 6.0. The 1% solution of this biopolymer was able to form a translucent and glossy film. And the solution of biopolymer was found to precipitate Kaolin solution and also stabilize the suspension of lactic acid bacteria within the test range of 0.25-1.00%. [Bacillus licheniformis, Biopolymer]. |
