PECTIN LYASE PRODUCTION BY PENICILLIUM-GRISEOROSEUM - EFFECT OF TEA EXTRACT, CAFFEINE, YEAST EXTRACT, AND PECTIN

Mycelial growth and production of extracellular pectin lyase by Penici llium griseoroseum at different concentrations of inducers were invest igated. The fungus was cultured in mineral medium using sucrose as a c arbon source and caffeine, yeast extract, tea extract or pectin as ind ucers. Caffeine, yeast extract and tea extract in the presence of sucr ose, and tea extract alone were capable of inducing pectin lyase in P. griseoroseum, even at low concentrations.
