  • Bacteriolytic complex, method for producing said complex and strain for carrying out said method
    Patent number: 7150985
    Abstract: The inventions relate to the field of medicine, veterinary and biotechnology and may be used for production of a drug for medical and veterinary purposes. A bacteriolytic complex, produced by the bacterium Lysobacter sp. XL1, has been proposed, which contains bacteriolytic enzymes (muramidase, muramoylalanineamidase, endopeptidase, a bacteriolytic enzyme with a molecular weight of about 22 kDa), protease, polysaccharide, and ballast components. The method of production of the bacteriolytic complex includes cultivation of the strain-producer on a nutrient medium containing glucose, peptone, yeast extract or yeast autolysate, phosphate salts of sodium and potassium, magnesium sulfate, potassium chloride, iron sulfate, and water.

  • Bacteriolytic complex, method for producing said complex and strain for carrying out said method
    Publication number: 20030148497
    Abstract: The inventions relate to the field of medicine, veterinary and biotechnology and may be used for production of a drug for medical and veterinary purposes. A bacteriolytic complex produced by the bacterium Xanthomonas campestris XL1 (the strain is deposited with the number VKM B-2249 D) has been proposed, which contains bacteriolytic enzymes (muramidase, muramoylalanineamidase, endopeptidase, a bacteriolytic enzyme with a molecular weight of about 22 kDa), protease, polysaccharide, and ballast components. The method of production of the bacteriolytic complex includes cultivation of the strain-producer on a nutrient medium containing glucose, peptone, yeast extract or yeast autolysate, phosphate salts of sodium and potassium, magnesium sulfate, potassium chloride, iron sulfate, and water.
