METHOD OF PREPARING POLYSACCHARIDE FROM BACILLUS MUCILAGINOSUS Russian patent published in 1999 - IPC

Abstract RU 2140454 C1

FIELD: biotechnology, microbiology. SUBSTANCE: for preparing a polysaccharide the strain Bacillus mucilaginosus is cultured on liquid nutrient medium containing the following components, g: peptone 0.8-1.2; molasses 6-8; Na₂HPO₄ 0.4-0.5; MgSO₄ 0.01-0.03; K₂SO₄ 0.01-0.03 and tap water 100 ml. Culturing is carried out at 30-32 C for 36-40 h. Spore material of culture Bacillus mucilaginosus, strain VKM B-1446 D, subjected for effect of ultraviolet radiation at wavelength 255-265 nm at time intervals 45 min, 45 min and 30 min is used for sowing. EFFECT: increased yield of polysaccharide. 1 dwg, 1 tbl, 2 ex
