摘要：An experimental procedure was carried out to maximize Chaetoceros gracilis growth. Chaetoceros gracilis , marine microalgae, is considered for feeding fisheries with no GMO (Genetically Modified Organisms) to avoid human health hazards. Furthermore, following United Nations Resolution on water, the microalgae is grown in photobioreactors due to its low water usage. To maximize the microalgae growth, an experimental design was carried out to analyze the effects of Light Intensity, CO₂ supply per day, Sparger type, Photoperiod and Inlet airflow, pH and water temperature were monitored but not controlled. It was found that Light intensity and CO₂ supply per day have statistical significance. Out of three possible scenarios, 1700 lux and 80 gr/day of CO₂, leads to a cell density at day three of 310×10^{4 cel/mL which represents 20% more of the density attained in day two under bag (standard) growing conditions. It was also found that water Ph has also a strong effect over cell density.}
