Abstract

Cochliobolus sativus and Fusarium culmorum produced pectin degrading enzymes, xylanase and carboxymethylcellulase when grown in a salts medium with an appropriate carbon source. There was little difference in enzyme production by the two organisms except for the greatly enhanced endo-polymethylgalacturonase activity when F. culmorum was grown with citrus pectin as the carbon source. When grown on powdered wheat straw, xylanase and carboxy-methylcellulase activities were not present until the late stages of incubation. It is suggested that degradation of pectin and xylan may be as important as cellulolysis in the saprophytic survival of these organisms.
