Contribution À La Caractérisation Microbiologique Et Enzymatique D'un Site Extrême :Les Tanneries Traditionnelles De Fès

ABSTRACT: Microorganisms in general are of abounding sources of unique enzymes that can be particularly
used in biotechnology. To face up the growing request of the industrialists notably in the field of biocatalysises,
numerous efforts are provided for the research of enzymes of interest. This concerns principally enzymes
coming from extremophiles microorganisms. These enzymes will be undoubtedly of a big interest to intervene in
close future in industrial techniques. It is as part of a possible promotion of microbic means by use of their
enzymes that we accomplished a first job which is interested in an extreme middle ' the traditional tanneries of
Fez. In a first shutter, we performed a physicochemical characterization of different stages of tanning; then we
undertook the isolation of microorganisms by a bet in culture on appropriate medium and at the end, we could
revealed certain of enzymatic potentialities (cellulase, pectinase, amylase, tannase and lipase) that the cleaned
microbic isolats culminates.
