Characterization of Lipolytic Microorganisms From Traditional Tanneries of Fez (Morocco) [ ]

This study led on the traditional tanneries of Fes aims at the characterization of the skins treatments stage. The most important of which are the one dropping of pigeons which by lipolytic effect of the microorganisms, would be at the origin of the skins degreasing and softening. The high lighting of the lipolytic microbial potential would be nil doubt mattering not only for the adoption of a method of non-polluting clean tanning of the environment but also for the unpublished biotechnological progress in the field of lipases application. The analysis of data collected further to the physic-chemical and microbiological characterizations in the various stages of tanning revealed the extreme character and the microbial wealth in this site. The pigeon’s droppings stage revealed three lipase producing yeasts. The kinetics of lipolytic activity for these yeasts with the biomass showed an important production of lipase in two phases suggesting the hypothesis of two synthesis lipases by the same yeasts.
