Abstract
Growth rate of marine microalgae (Nannochloropsis oculata, Tetraselmis chuii, and Porphyridium sp.) in urea wastewater based medium is investigated. Microalgae were cultivated in sterile seawater under controlled conditions with varying amounts of urea: 0 mg/L (as a control variable), 25 mg/L, 50 mg/L, 75 mg/L, 100 mg/L, and 150 mg/L. During the experiment, environmental parameters, including pH, temperature, dissolved oxygen (DO), and salinity, were monitored. The study showed that the microalgae cell growth rate of Nannochloropsis oculata was 0.44 x 104 cells/mL/day. While Porphyridium sp. and Tetraselmis chuii were found to be 0.61 x 104 cells/mL/day and 0.56 x 104 cells/mL/day. The optimum biomass productivity of microalgae Nannochloropsis oculate, Porphyridium sp. and Tetraselmis chuii was found to be day, respectively.
