Activity of pectinases, amylases, and saccharase in Pythium spp.

The activity of pectine-lyase, polygalacturonase, pectine-methyl-esterase, amylase, and saccharase in Pythium ultimum, Pythium oligandrum, and Pythium debaryanum was determined. Cultures of fungi were cultivated under different temperatures and pH-values within 24 hours and 15 days. The optimum temperature for production of the mentioned enzymes was found to be 24 degrees C. Furthermore, the influence of pH and age of culture on activity of enzyme was investigated. The same trend was found in all the fungus species examined.
