Notes:
Ten Aspergilli and Penicillia were tested for the capabilities of their extracts in degrading L-arabinose or L-arabonate nonphosphorolytically. L-arabonate dehydratase was nearly absent, while the reverse reaction of 2-keto-3-deoxy-L-arabonate (KDA) aldolase was operative in extracts of all the tested organisms grown on L-arabinose or L-arabonate as the sole carbon source. Degradation of different related substrates by cell-free extracts of Aspergillus ustus showed that L-arabonate, D-gluconate, D-galactonate and D-galactonic acid-γ-lactone were degraded under these conditions. Chromatographic studies identified the L-arabonate degrading products of such degradation in A. ustus as KDA (traces), pyruvic acid and α-ketoglutaric acid.
