Abstract

Microalgae are increasingly employed for production of a wide range of industrial chemicals. Light intensity is an important parameter affecting microalgae cell growth. Analysis of light penetration into the algae culture broth is important for an efficient photobioreactor design. In this study, effect of light intensity on the growth of microalgae species Chlorella variabilis was investigated in a compartmentalized photobioreactor system. The optimal range of light intensity for highest growth rate (0.037 h-1) and cell concentration (0.30 gdw/L) was found to be 17 - 36 klux, lower light intensities yielded in significantly slower growth and lower cell concentrations. Photoinhibition effect was clearly observed at light intensities above 36 klux. Maximum photobioreactor depth which can provide 95% of the maximum growth rate was determined to be 8 cm.

Özet

Mikroalgler çeşitli endüstriyel kimyasalların üretiminde artarak kullanılmaktadır. Işık şiddeti mikroalg hücre büyümesini etkileyen önemli bir değişkendir. Işığın alg kültürüne nüfuzunu incelemek verimli bir fotobiyoreaktör tasarımı için önemlidir. Bu çalışmada, mikroalg türü olan Chlorella Variabilis'in büyümesine ışık şiddetinin etkisi bölümlendirilmiş bir fotobiyoreaktör sisteminde incelenmiştir. En yüksek büyüme hızı (0.037 h-1)ve hücre derişimi (0.30 gdw/L) için ideal ışık şiddeti aralığı 17-36 klüks olarak bulunmuştur, daha düşük ışık düzeyleri büyüme hızı ve hücre derişimini önemli ölçüde düşürmektedir. Fotoinhibisyon 36 klüks üzerindeki ışık şiddetlerinde açıkça gözlenmiştir. En yüksek büyüme hızının %95'ini sağlayabilecek en yüksek fotobiyoreaktör derinliği 8 cm olarak belirlenmiştir.
