Etude du systeme lipolytique de Penicillium verrucosum var cyclopium [Westling] II Conditions de production du systeme lipasique

The speci 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 acticity. 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]

Etude du systeme lipolytique et penicillium verrucosum par cyclopium [Westling]

The principal properties of the lipase produced by Penicillium verrucosum var cyclopium Westling, were studied.It has been shown that optimal temperature for activity is 30°C and the optimal pH is 8. This lipase is thermal resistant and able to hydrolyse easier the tributyrine than olive oil
