Poly(aspartic acid) degradation by a Sphingomonas sp. isolated from freshwater

Appl Environ Microbiol. 1999 Sep;65(9):4268-70. doi: 10.1128/AEM.65.9.4268-4270.1999.

Abstract

A poly(aspartic acid) degrading bacterium (strain KT-1 [JCM10459]) was isolated from river water and identified as a member of the genus Sphingomonas. The isolate degraded only poly(aspartic acid)s of low molecular masses (<5 kDa), while the cell extract hydrolyzed high-molecular-mass poly(aspartic acid)s of 5 to 150 kDa to yield aspartic acid monomer.
