Synthesis of Ester Oligomer by Aspergillus niger Lipase

Abstract

Lipase from Aspergillus niger NRRL 337 catalyzed the synthesis of esters from various dicarboxylic acids and diols. Among the esters synthesized, those from 1,13-tridecanedioic acid and 1,3-propanediol were separated by gel permeation chromatography. The constitution of the purified ester was determined by using IR and MS. The dominant components of synthesized esters were pentamer and heptamer, and both end groups of the pentamer and heptamer were hydroxyl. The possible reaction sequence in synthesis of ester oligomer by Aspergillus niger lipase is described. © 1984, Japan Society for Bioscience, Biotechnology, and Agrochemistry. All rights reserved.
