概要
- 論文の詳細を見る
A process for the production of L-tagatose from galactitol has been developed. An organism isolated from soil, Klebsiella pneumoniae strain 40b, was found to convert galactitol to L-tagatose at a higher rate when glycerol was added to the reaction mixture than when no glycerol was added to the reaction mixture. The cells grown on 1.0% xylitol showed maximum conversion activity. The conversion rates were about 90%, 80%, 70% and 60% with 0.5%, 1.0%, 1.5% and 2.0% galactitol concentration, respectively. Since the strain does not utilize galactitol and L-tagatose, almost 100% of galactitol consumed was converted to L-tagatose. This is the first report of L-tagatose production by microbial cells.
