标题：EFFECT OF LIGHT PATH LENGTH OF TUBES ON GROWTH RATE OF NANNOCHLOROPSIS OCULATA USING INDUSTRIAL SCALE TUBULAR PHOTOBIOREACTOR IN THE MARINE HATCHERY
摘要：Microalgal biotechnology have to solved for culture system for culturing of algae species. In this case, it should be optimised with key design parameters in an integrated way of photobioreactor used for cultivation of microalgae. The diameter of the tube was the predominant factor to determine the light gradient.The experiments, which examined the effect of different light path length (LP) of tubes on the cell growth of N. oculata show that there was a relationship between light path length and growth rate. 50 mm LP PBR and nd 80 mm LP tubular PBR were inoculated with 61.0 x 106 cell/mL and 71.0 x 106 cell/mL, respectively. In the first 15 days, Cell numbers were increased in both systems without any fluctiotion, the maxiumum cell densities were also recorded as 590.67±8.60 x 106 (50 mm LP) cell/mL and 396.83±6.75 x 106 (80 mm LP) cell/mL.Our results of biomass yield which was calculated as 2.8 g/L day for 50 mm LP PBR system.
