3.1. Screening of enzymes’ producers by a selective agar plates method<br>The ability of different commercial strains and natural isolates<br>from different habitats to produce extracellular proteases, cellulases, amylases and pectinases was examined using selective agar<br>medium plates. Namely, a myriad of different strains was cultivated on agar plaits that contain casein, CM-cellulose, starch, or<br>pectin as one of the exclusive nutrients. Such mediums require<br>extracellular enzyme activity to facilitate successful hydrolyzation<br>and utilization of the nutrients from the media and enable microbial growth. In turn, produced enzymes can be easily visually<br>detected by the appearance of the clear zones surrounding grown<br>microbial colonies. Special attention was devoted to inspection of<br>hydrolytic activities of extremophilic strains (eg. Pseudomonas),<br>since these enzymes naturally (per se) have a number of special<br>properties like extreme stability
