Abstract
Polygalacturonase activity of Penicillium expansum was evaluated in th e culture filtrate after removal of the mycelial mass. The best cultur e condition for enzyme production was growth in unbuffered mineral med ium in the absence of yeast extract. Production of the enzyme was depe ndent on growth medium pH and was maximal at acid pH.
