Production of arabitol by microorganism of genus rahnella

TLDR: In this paper, a pre-cultured Rahnella aquatilis (JCM-1683) was inoculated in a medium containing 1-20wt.% of D-arabinose and reacted to produce arabitol in the reaction liquid.

Abstract: PURPOSE:To easily produce D-arabinose in a mass at a low cost by culturing a microbial strain of genus Rahnella under aerobic condition in a medium containing D-arabinose. CONSTITUTION:A precultured Rahnella aquatilis (JCM-1683) is inoculated in a medium containing 1-20wt.% of D-arabinose, a nitrogen compound such as peptone, an inorganic salt such as Mg, etc., and cultured at 20-37 deg.C for 1-10 days under aerobic condition to produce arabitol in the medium. As necessary, the above microorganism of genus Rahnella is cultured in a medium containing monosaccharide (e.g., arabinose), organic acid (e.g., gluconic acid), nitrogen compound (e.g., peptone), etc., to obtain microbial cells. The microbial cells or treated cell such as extract of the cell are added to a solution of D-arabinose having a concentration of 1-40wt.% and reacted to produce arabitol in the reaction liquid.
