1
Celluloytic bacteria, -Gram positive, Gram negative and actinomycetes-were used to study their catabolic pathways of carbohydrate. It was found that Embden-Meyerhof -Parnas(EMP) pathway and hexose monophosphate(MHP) shunt were operated in Cellulomonase sp. CSI-1, C. flavigena, and Pseudomonas fluorescens subsp. cellulosa when they were cultured in a glucose containing medium, whilst gluconate was catabolised mainly via Entner-Doudoroff(ED) pathway, and to some extend through HMP shunt. Enzymes of ED pathway in the organisms were induced by gluconate. On the other hand Nocardia cellulans catabolised glucose and gluconate via EMP pathway and HMP shunt. The growth rate of N. Cellulans on gluconate were much slower than that on glucose.
