This study was designed to furnish evidence showing the possible pathways utilized by Actinoplanes philippinensis ATCC 11242 in the dissimilation of D-glucose. A. philippinensis was grown in a defined medium using D-glucose as its carbon source. Escherichia coli ATCC 9257h was cultivated under the same conditions and used for comparative purposes. Quantitative enzyme assays on cell free extracts were determined spectro-photometrically for glucokinase, glucose-6-phosphate dehydrogenase, phosphoglucoisomerase and 6-phosphogluconate dehydrogenase. Enzymic activities showed the presence of glucokinase, glucos-6-phosphate dehydrogenase and phosphoglucoisomerase in A. philippinensis. Six-phosphogluconate dehydrogenase on the basis of observed activity is either absent or may be present in very low concentrations in this species of Actinoplanes. If so, this substantially rules out the H.M.P. pathway for dissimilation of glucose by this bacterium. A qualitative test for aldolase indicated its presence in the organism. Possible pathways in D-glucose catabolism for A. philippinensis would appear to be either the Entner-Doudoroff, Embden-Meyerhof, or a modification of these pathways.
