| Abstract: | The levels of chitinolytic enzymes and chitinolytic bacteria in the digestive tract of feeding and fasting cod were compared. Enzyme activities within a given tissue were of a similar order irrespective of the presence of chitinolytic bacteria and/or chitin. Cod chitinase and chitobiase are therefore endogenous and constitutive enzymes. Fasting cod had similar numbers of bacteria within the gastro-intestinal compartments as feeding fish. Representative bacterial isolates from fasting fish were characterized. |
