Denizel kuluçkahanede Nannochloropsis oculata dış ortam kültüründe endüstriyel ölçekli tübüler fotobiyoreaktör ile FRP (fiberglas ile güçlendirilmiş plastik) panel fotobiyoreaktörün karşılaştırılması

Mikroalg üretimi balık kuluçkahaneleri için kilit noktası olmakla birlikte hala optimizasyonu tamamlanmamış ve çözülmesi gereken problemlere sahiptir. Nannochloropsis oculata önemli bir canlı yem kaynağıdır ve deniz balıkları üretiminde larvaların beslenmesi amacıyla üretilmektedir. N. oculata, sera içerisinde tübüler ve FRP panel fotobiyoreaktörlerde üretilmiştir. Tübüler FBR 701,7 x 106 hücre mL-1 maksimum yoğunluğa ulaşırken, FRP panel FBR ise 245 x 106 hücre mL-1 maksimum yoğunluğa ulaşmıştır. Ayrıca, tübüler ve FRP panel FBR’ler için maksimum tahmini kuru ağırlıklar da sırasıyla 3,249 g L-1 ve 1,47 g L-1 olarak hesaplanmıştır. Sonuç olarak, tübüler FBR’ün, FRP panel FBR’e göre daha verimli olduğu bu çalışma ile ortaya konulmuştur.

Comparison of industrial-scale tubular photobioreactor to FRP (fiberglass reinforced plastic) panel photobioreactor on outdoor culture of Nannochloropsis oculata in the marine hatchery

Microalgal culture is a key procedure in marine fish hatcheries, but this activity is far from optimized and has several problems remain to be solved.Nannochloropsis oculata are important to live feed organisms, which are used to rear the larvae of marine finfish. N. oculata were cultivated in tubular PBRand FRP panel PBR in a greenhouse. Tubular PBR was reached 701.7 x 106 cells mL-1 as its maximum cell density and FRP panel PBR was reached 245 x106 cells mL-1 as maximum. Also, estimated maximum dry weights of tubular and FRP panel PBRs were calculated as 3.249 g L-1 and 1.47 g L-1, respectively.Consequently, tubular PBR was showed that it is more efficient than FRP panel PBR in this study.
