Process for producing polyester, process for producing substituted alpha-hydroxy acid, and Clostridium beijerinckii strain HICA432

摘要

A process for producing a polyester, the process comprising the steps of (1) fermenting a saccharide with a microorganism to obtain at least one substituted alpha -hydroxy acid represented by the formula: HO-CHR-COOH (wherein R represents a hydrocarbon group having 1 to 10 carbon atoms), and (2) polymerizing the substituted alpha -hydroxy acid or a derivative thereof.
