Description

ABSTRACT:
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 α-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 α-hydroxy acid or a derivative thereof.
