Recent studies indicate that the microbial ecosystem is not limited to specific areas but may also be found in extreme temperature, extreme salt, extreme pH, extreme pressure, etc. Haloarchaea enzymes are very resistant to salinity stress and also have thermotolerant properties according to environmental conditions. Very few studies have been published about Archaea till date. Firstly, Archaea were isolated from Tuz Lake by traditional methods. Thereafter, the antibiotic resistance of the organisms was investigated. The antibiotic resistance of Archaea was determined by disk diffusion method. The aim of this work was to investigate the effects of environmental conditions on growths of halophilic archaea isolated from Lake Tuz in Turkey. In this study, halophilic archaea isolated from Lake Tuz were investigated under different salt, nitrogen and carbon sources. The best NaCl tolerance of isolated strains is 10% for B8 isolate. The highest nitrogen tolerance is 1% protease peptone for B7 isolate. The best strain for the use of different carbon sources is B7 isolate, and this rate is 1% starch. The study showed that Archaea have tolerance to different environmental conditions.
