Effects of photoperiod, salinity and pH on cell growth and lipid content of Pavlova lutheri

Year: 2013

Type: article

Abstract: The aim of the present work was to study the effects of photoperiod, salinity and pH on growth and lipid content of Pavlova lutheri microalgae for biodiesel production in small-scale and large-scale open-pond tanks. In a 250-mL flask, the cultures grew well under 24 h illumination with maximum specific growth rate, μ max , of 0.12 day−1 and lipid content of 35 % as compared to 0.1 day−1 and 15 % lipid content in the dark. The salinity was optimum for the cell growth at 30–35 ppt, but the lipid content of 34–36 % was higher at 35–40 ppt. Algal growth and lipid accumulation was optimum at pH 8–9. Large-scale cultivation in 5-L and 30-L tanks achieved μ max of 0.13–0.14 day−1 as compared to 0.12 day−1 in small-scale and 300L cultures.
