title: [Study of the lipolytic system of Penicillium verrucosum var cyclopium (Westling). II. Conditions for the production of the lipase system].
abstract: The specie Penicillium verrucosum var cyclopium (Westling) has showed that Media containing peptones, especially, trypticase, as a source of nitrogen and maltose or glucose as a source of carbon are most efficient for a good stimulation of the lipolytic activity. Salt, especially Mg++ ion and some oligo- elements exhibit a marked effect on enzyme production. On the other hand, addition of lipids to the growth medium inhibited the lipase production. Shaking of the medium decreases the amount of lipase production but allows an early growth of P. verrucosum var cyclopium (Westling).
