Abstract

A lipase secreted by Propionibacterium acidi-propionici was purified 52-fold with 27% recovery by employing a 3-step purification protocol. The enzyme has a small molecular mass (Mr = 6000-8000) as determined by gel filtration and ultracentrifugation. It hydrolysed palm oil, coconut oil, castor oil, olive oil, groundnut oil and tributyrin. Enzyme activity was inhibited by Ni2+, Ba2+, Mg2+, Cu2+, EDTA, iodoacetamide, N-acetylimidazole and nonidet P-40 but stimulated by Ca2+, Co2+, K+, Fe2+, SDS and N-bromosuccinamide. The enzyme showed substrate inhibition for both tributyrin and p-nitrophenyl acetate.
