PROCESS FOR PRODUCING 3-HYDROXYPROPIONALDEHYDE

摘要

A process in which 3-hydroxypropionaldehyde can be produced from glycerin at high conversion rate. This process is characterized by including the step of dehydrating glycerin with bacterial cells and/or bacterial cell treatment product containing diol dehydratase and/or glycerol dehydratase optionally together with a diol dehydratase reactivating factor and/or a glycerol dehydratase reactivating factor under such conditions that the quotient of catalytic amount [X (U/g glycerin)] of diol dehydratase and/or glycerol dehydratase divided by square of glycerin concentration [Y (g/100 ml)], X/Y<2>, is in the range of 10 to 8000 so as to obtain 3-hydroxypropionaldehyde.
