Abstract:

 Microalgae have the potential to grow at a rapid rate, which allows them to surpass other living creatures in terms of their prevalence in scientific research settings. Through their growth in wastewater, they are able to make a contribution to the treatment of wastewater. In addition, microalgaes metabolic components make them suitable for industrial applications. In this work, we investigated at how copper stress at various concentrations affected the biomass, carbohydrate, bioethanol, and antioxidant activities of Borodinellopsis texensis cultivated in 25 wastewater. The maximum biomass concentration was 0.79  0.02 gL at control group. In addition, carbohydrate content was the highest in a medium with 0.025 gL copper, at 0.29  0.02 gL. The bioethanol productivities of Borodinellopsis texensis were 174.4 mgg for 0.025 gL Cu and 141.8 mg g for the control. DPPH, CAT, SOD and APX tests were performed to examine the antioxidant activities of Borodinellopsis texensis. The DPPH maximum scavenging, CAT, SOD, and APX activities of Borodinellopsis texensis were 83, 17.4 µmolmg, 8.87 µmolmg, and 32.7 µmolmg at 0.025 gL of Cu, respectively. We are going to continue our investigation into the ways in which microalgae react when it is subjected to copper stress in larger reactors in the future with the assistance of this study.

 Mikroalgler hızlı büyüyebilme özellikleri ile diğer canlıların önüne geçerek bilimsel çalışmalarda sıklıkla kullanılabilirler. Onlar atıksu içerisinde büyütülerek atıksuyunda arıtımına katkı sağlayabilirler. Ayrıca, mikroalgler içerisindeki metabolik bileşikler sayesinde sanayide kullanılabilir. Bu çalışmada biz 25 atıksu içerisinde büyütülen Borodinellopsis texensisin çeşitli konsantrasyonlardaki bakır stresine karşı biyokütle, karbonhidrat, biyoetanol ve antioksidan aktivitelerine göstermiş olduğu değişimi inceledik. Maksimum biyokütle konsatrasyonu 0,79  0,02 gL ile kontrol grubunda bulundu. Buna ek olarak, en yüksek karbonhidrat içeriği 0,025 gL bakır konsantrasyonunda 0,29  0,02 gL olduğu gözlemlendi. Borodinellopsis texensisin biyoetanol verimi 0,025 gL Cu konsatrasyonunda 174.4 mgg iken, kontolün biyoetanol verimi 141,8 mgg olarak bulundu. Borodinellopsis texensisin antioksidan aktivitelerini incelemek için DPPH, CAT, SOD ve APX testleri yapıldı. Borodinellopsis texensisin maksimum DPPH yakalama aktivitesi 83, CAT aktivitesi 17,4 µmolmg, SOD aktivitesi 8,87 µmolmg ve APX aktiviteside 32,7 µmolmg olarak 0,025 gL Cu konsantrasyonunda bulundu. Bu çalışmanın yardımıyla gelecekte mikroalglerin daha büyük reaktörlerde bakır stresine maruz kaldığında nasıl tepki verdiği konusundaki araştırmalarımıza devam edeceğiz.
