Mass cultivation of microalgae is gaining importance nowadays, because of its bioprospecting property. In this study laboratory scale tubular photobioreactor was constructed for marine microalgae cultivation using cheapest materials such as wooden sheets, wooden reapers, aquarium light, glass tube, and UPVC, PVC couplings. The two marine microalgae Nanochloropsis occulata and Chaetoceros calcitrans were studied. Effect of growth medium, pH was determined in normal culture technique and mass cultivation was carried out in tubular photobioreactor. The growth curve of marine microalgae with various inoculation volume and days of incubation were also determined. F2 medium and pH 8 is suitable for the growth of the two marine microalgae. The biomass production is reached maximum level in 8 days of cultivation at 1.5 OD of inoculum volume. The biomass productivity is higher in tubular photobioreactor than the normal culture system.
