This study was carried out with the aim of determining the production of gelatinase enzyme in isolates by making halofylic bacteria isolation from the skin of sheep preserved by salt. As a result, the optimal temperature stability of the enzyme, the optimal salt concentration and plasmide-coded resistance position were studied. In the reproduction of halofylic bacteria isolated from skin samples, periodically increasing levels (5%, 10%, 15%, 20%, 25 and 30%) of salt content were used. According to Bergey’s Manuel of Determinative Bacteriology, the study studied 280 bacterial sulphes that were isolated. Streptococcus spp is a substance that gives positive results in the enzyme activity tests. and Staphyllococcus spp. It was found and observed that the insulates have the best reproductive capacity in incubation conditions at 30 oC in a nutrient environment with an optimal 10% salt concentration, and the bacterial reproduction is slowed in the event of increased salt concentration. In the determination of the activity of the enzyme of Jelatinase, the optimum enzyme activity was found in the nutritional environments containing 1.5% and 1.5% and 2% and 3% using the nutritional environment containing jelatin. Only 2.8% of halofylic bacteria isolated from the sheep's skin found positive gelatinase activity. Halofil juice showing the activity of the plasmid-coded enzyme gelatinase has not been found
