The effect of culture media on growth and chlorophyll content of Nannochloropsis oculata in tubular photobioreactor

A major challenge for industrial microalgae production is cultivation problems. Photobioreactors with different volumes are one of the systems applied for microalgal mass cultivation. Following species identification, design and optimization of a photobioreactor are necessary. In the present study, growth (doubling time, cell density and dry weight) and chlorophyll a content of Nannochloropsis oculata were investigated using Guillard (f/2) and Walne media for two periods of 15 days. Cells density, chlorophyll a and dry weight of microalgae grown in both media were measured with three replications. The results showed significant influence (P
