ISOCITRATE LYASE IN AN ALGINOLYTIC BACTERIUM

Abstract

Glyoxylate has been discerned as an apparent intermediate in mannuronate dissimilation by A. alginicum. Isocitrate lyase was demonstrated in extracts of the bacterium, even after prolonged culture on seawater nutrient broth. Resting cells were able to oxidize glyoxylate slowly, but none of the enzymes usually accounting for glyoxylate catabolism were found in cell-free extracts.
