A tot al of 42 1 microbial strains isolated from the soil and water samples were undertake in th is study. Forty vitamin B)2producing strains were obta ined by microbiological assay method, in which, five strains were capable of producing vit ami n BI2more tha n 0.08 mg / L. And strain CCU-045 possess highest vitamin BI2 prod uci ng ability, its yield high up to 0.174 mg / L. The composit ion of optimal synthetic medium for CC U 045 to produce vitamin B)2 was 3 % methanol (by volume ); 1.5 giL (NH2)2CO; 1.5 giL (NH4)2S04; 3 mg / I., CoCl2" 6 H20 ; 5 mg/L FeS04-7 H20 ; 5 mg/L e aCl2' 2 H20 ; 0. 15 mg/L MgS04 ‧ 7 H20 ; 0.2 mg /L yeast extract and 1.5 g fL for each of KH2P0 4 and ICzHP04( pH 7.0). The optimal cultural con ditions for vitamin BI2 prod uction were as follows: incubation temperature, 30°C; agitation , 115 rpm and 100mL medium in 500mL Hin ton flask. The yield of vitamin HI2 of CCU 045 cultivated for "1 days under this condition was 0.184 mg / L. The products of vitamin B)2-producing strains including ceu 045 were analyzed by UV sp ectrophotomet ry, thin-layer ch romatogra phy and high performance liquid chromatography. All of these strains were confirmed to prod uce vitamin B12.
