摘要：

Dihydroxyacetone phosphate is essential for the synthesis of polyhydroxylated compounds used as components or precursors of active pharmaceutical substances, such as antibiotics or glycosidase inhibitors. Dihydroxyacetone phosphate was produced by enzymatic oxidation of L-α-glycerophosphate in the presence of glycerophosphate oxidase or Aerococcus viridans coimmobilized with a hydrogen peroxide-decomposing enzyme. The microencapsulation of A. viridans with catalase in sodium alginate showed a conversion of 98.5%; the conversion percentage remained constant in all five runs. Liquid chromatography of the product revealed that the product peak corresponded to that of the dihydroxy-acetone phosphate internal standard. This indicated a high degree of product purity.
