METABOLISM OF PHYTOPATHOGENIC BACTERIA II

Abstract

Studies with sonic preparations of representative species of phytopathogenic bacteria demonstrate the presence in these organisms of certain key enzymes involved in the glycolytic and shunt pathways of glucose metabolism. The evidence suggests that species of Xanthomonas, Pseudomonas, and Agrobacterium metabolize glucose by the shunt pathway and either by the 6-phosphogluconate-splitting system, the pentose cycle or both. Species of Erwinia may use either the glycolytic or the oxidative route whereas Corynebacterium spp. appear to utilize the latter pathway, possibly via the pentose cycle.
