- 論文の詳細を見る
We isolated about 500 isopropanol(IPA)-assimilating bacteria from many soil samples, among which 23 strains produced vitamin B_<12>. Taxonomical studies of the best producer, designated strain Hi16.3,showed that it belonged to the genus Arthrobacter. Vitamin B_<12> production by the strain was higher than that by 12 other authentic Arthrobacter spp. using glucose as a sole carbon source. In fed-batch culture, the maximum production yield with strain Hi16.3 (named A. hyalinus) was 2 mg/l in the culture broth, when 80 ml of IPA/l broth was consumed.
