Sažetak
Production of different pectinolytic enzymes was attempted using the actinomycete strain Streptomyces lydicus in submerged fermentation. Polygalacturonase and pectin lyase activities were detected in the culture supernatant, but the strain was not able to produce pectin esterase. Polygalacturonase production was studied in submerged, slurry-state and solid-state fermentation systems. All the experiments were carried out under static and shaking conditions. Solid-state fermentation under static condition was found to be promising. Various agroindustrial residues were tried as substrates for solid-state fermentation. Wheat bran was proved to be the best substrate.
