Özet

In this study, the influence of solar inclination angles on biomass growth and the biomolecule profile of Chlorella pyrenoidosa (C. pyrenoidosa) were analyzed in the vertical flat–panel photobioreactor (FPPBR). The growth of C. pyrenoidosa was analyzed at three different solar inclination angles (32.9°, 47.9°, and 90°) in a natural open environment with BG-11 medium and poultry excreta leachate (PEL). The maximum yield of biomass was obtained at 2.40 g/L with PEL and 1.45 g/L with BG-11 medium at a solar inclination angle of 47.9°. The biomass yield with PEL and BG-11 was 5.09–10.26%, 3.94–5.72%, respectively, while biomass productivity with PEL and BG-11 was 5.27–10.63%, 4.06–5.90% higher at a solar inclination angle of 47.9° as compared to 32.9°. The average temperature and radiation of FPPBR were recorded ≈3.90 ± 0.40% and ≈17.28 ± 2.23% higher at a solar inclination angle of 47.9° as compared to a solar inclination angle of 32.9°. The inclined radiation was acquired the maximum area of FPPBR. Results indicated that solar inclination angles enhanced the productivity of algae in FPPBR.
