title: Cellulolytic activity of some Pythium species.
abstract: The cellulolytic activity of Pythium ultimum and P. oligandrum was investigated in vitro during the mycelium growth. It was found that under a constant temperature of 24 degrees C the cellulolytic activity was changed according to the pH of the medium. The optimum of cellulolytic activity in P. ultimum was recorded at neutral pH, whereas that in P. oligandrum in acid medium. The enzymatic production depended on the age of culture as well.
