Degradation of homophthalic acid byAspergillus niger

Abstract

The fungusAspergillus niger degraded homophthalic acid through the involvement ofo-hydroxyphenylacetic acid and homogentisic acid as the metabolic intermediates. Isolation of intermediates was carried out by extracting the spent medium and by using inhibitor in replacement culture techniques. Metabolites were characterized by various physicochemical methods. Oxygen uptake studies and enzyme investigations also confirmed that the degradation of homophthalic acid follows through these intermediates in the fungus.
