Abstract: A pancreatic lipase inhibitor screening model was constructed, which combined with determination of inhibitory activities of amylase, protease and lipase. Three strains FIM-1013, FIL-19 and FIMe-3 were obtained through target screening of microbial broths from soil organisms by this model. The lipase inhibitory activites of FIM-1013,FIL-19 and FIMe-3 were 61%,53% and 42%, the amylase inhibitory activites were 0,7% and 3%, and the inhibitory protease activity were 6%,4% and 0. The results indicated that the three strains could produce very potent selective inhibitor of pancreatic lipase which deserved further research.

Key words: pancrelipase, inhibitor, screening model, protease, amylase
