Two samples from two extreme ecosystems (El Oued soil and Chott Melghir salt) were used in this study. Sixty-nine actinomycete colonies were collected from three actinomycete-selective media (ISP5, ISP2, AIA) supplemented with antibacterial and antifungal agents. These media were inoculated with these soil and salt samples. The strains were purified on the same media used for isolation. Twenty strains were selected for enzymatic activity testing. The enzymatic activities of these bacteria were tested using specific media for each activity test. The strains all showed activity on catalase, but the vast majority were not capable of reducing nitrate to nitrite, while most of the strains showed catalytic action on gelatin, starch, pectin, lecithinase, lipoproteinase, amylase and cellulose
