Ektoin, halofil mikroorganizmalar tarafından üretilen ve çevresel streslere karşı koruyucu özellikleri nedeniyle çeşitli endüstrilerde yaygın olarak kullanılan uyumlu bir çözünendir. Bu çalışmada, Türkiye’deki aşırı tuzlu bir ortam olan Tuz Gölü’nden, besiyeri optimizasyonu yapılmaksızın yüksek düzeyde ektoin üretebilen bakterilerin izolasyonu ve karakterizasyonu amaçlanmıştır. Şereflikoçhisar ve Cihanbeyli bölgelerinde rastgele seçilen alanlardan toplanan su ve toprak örneklerinden, %3 ila %21 arasında değişen NaCl konsantrasyonlarına sahip et-pepton agar kullanılarak yapılan seçici kültürleme ile bakteri izolatları elde edilmiştir. Toplamda 22 izolat tuz toleransı ve ektoin üretim potansiyeli açısından taranmış, en yüksek tuz toleransına ve belirgin koloni morfolojisine sahip 10 izolat detaylı analize alınmıştır. 16S rRNA dizilemesiyle yapılan moleküler karakterizasyon, bu izolatların Halomonas, Chromohalobacter ve Salinivibrio cinslerine ait olduğunu göstermiştir. Yüksek performanslı sıvı kromatografisi (HPLC) analizleri, Salinivibrio sp. (İzolat 12) ve Halomonas sp. (İzolat 21) türlerinin sırasıyla 296.88 µg mL-1 ve 202.49 µg mL-1 ektoin üretimiyle en yüksek verimi gösterdiğini ortaya koymuştur. Ektoin verimini artırmak için farklı azot kaynaklarının etkisini değerlendiren Plackett-Burman deney tasarımı uygulanmış ve Salinivibrio sp. için peptonun ektoin üretimini anlamlı şekilde artıran bir faktör olduğu (p <0.05) belirlenmiştir. Bu çalışma, Tuz Gölü'nden izole edilen halofilik bakterilerin endüstriyel ektoin üretiminde biyoteknolojik potansiyelini vurgulamakta ve ektoin verimini artırmada besiyeri optimizasyonunun önemini göstermektedir. İleri optimizasyon çalışmaları, ticari ektoin üretimi için ölçeklenebilir süreçlerin geliştirilmesine olanak sağlayabilir.

Ectoine, a compatible solute produced by halophile microorganisms, is widely used in various industries due to its protective properties against environmental stress. This study aimed to isolate and characterize bacterial strains capable of producing high levels of ectoine without medium optimization from Tuz Lake, an extremely saline environment in Turkey. Bacterial isolates were obtained by selective culturing on meat peptone agar containing NaCl concentrations ranging from 3% to 21%, using water and soil samples collected from randomly selected sites in the Şereflikoçhisar and Cihanbeyli regions. A total of 22 isolates were screened for salt tolerance and their potential for ectoine production. Among them, 10 isolates with the highest salt tolerance and distinctive colony morphology were selected for further analysis. Molecular characterization via 16S rRNA sequencing identified these isolates as belonging to the genera Halomonas, Chromohalobacter, and Salinivibrio. High-performance liquid chromatography (HPLC) analysis revealed that Salinivibrio sp. (Isolate 12) and Halomonas sp. (Isolate 21) exhibited the highest ectoine production, yielding 296.88 µg mL-1 and 202.49 µg mL-1, respectively. To optimize ectoine yield, a Plackett-Burman experimental design was applied, evaluating the effects of different nitrogen sources. Peptone was identified as a statistically significant factor (p < 0.05) for enhancing ectoine production in Salinivibrio sp. This study highlights the biotechnological potential of halophilic bacteria from Tuz Lake for industrial ectoine production and emphasizes the importance of medium optimization in improving ectoine yields. Further optimization may enable the development of scalable processes for commercial ectoine production.
