Abstract
A pectinolytic bacterium was isolated from a mixed microbial population by means of a chemostat enrichment procedure. The bacterium, which was identified asErwinia carotovora, grew only on highly methylated pectin and produced a pectin lysase which released unsaturated monomer and dimer from 71% esterified citrus pectin. The pectin lyase was inducible only by pectins having a high methyl content and in pectin-limited chemostats its synthesis passed through a maximum at a dilution rate close to 0.04h-1.
