Mikrobiyal Yakıt Hücresinde 2-Hydroxy-1,4-Naphthoquinone'nin Elektrik Üretimine Katkısı
Mikrobiyal yakıt hücreleri (MYH) organik maddelerin parçalanması sonucunda direk elektrik enerjisininüretildiği biyolojik sistemlerdir. Son yıllarda, güç artırımı amacıyla mikrobiyal yakıt hücrelerinde anotperformansını arttırmak için çeşitli mediyatörler kullanılmıştır. Bu çalışmada, 2-hydroxy-1,4-naphthoquinone(HNQ) mediyatörünün çift bölmeli bir mikrobiyal yakıt hücresinde elde edilen güç miktarına katkısıbelirlenmiştir. MYH, sırasıyla mediyatörsüz, 100, 200 ve 400 µM HNQ mediyatörlü işletilmiştir. Mediyatörsüzişletim esnasında, elde edilen güç yoğunluğu 16 mW/m2 olarak tespit edilirken, en yüksek güç yoğunluğu 200µM HNQ ilavesi ile 64,4 mW/m2 olarak belirlenmiştir.
Contribution of 2-Hydroxy-1,4-Naphthoquinone on Electricity Generation in Microbial Fuel Cell
Microbial fuel cells (MFC) are biological systems in which electricity is directly generated by degradation oforganic matter. Recently, various mediators have been used to enhance the anode performance in microbial fuelcells for increasing power generation. This study presents the contribution of 2-hydroxy-1,4-naphthoquinone(HNQ) on power generation in two-chamber MFC. The system was operated with no mediator, 100, 200 and 400µM HNQ, respectively. While the maximum power density was 16 mW/m2 during operation without mediator,it increased to 64,4 mW/m2 at 200 µM HNQ.
