Abstract: Autotrophic cultivation of microalgae induces low biomass and lipid production and is difficult to be used in pilot scale production. Heterotrophic and mixotrophic algae allows higher growth rate, which in turn can accumulate higher biomass and lipid. Enhanced biomass and lipid production is crucial to use oleaginous microalgae for industrial application of biodiesel production. A fresh water microalga was isolated from waste water treatment plant and identified as Scenedesmus obliquus. The isolate was grown u… Show more

“…Similar results were found in Crypthecodinium cohnii, where NaNO 3 supported much higher lipid content (26.9% of dry weight) than other nitrogen sources, including urea [23]. In Scenedesmus, NaNO 3 was also reported to yield the highest lipid content among other nitrogen sources [24]. In addition to the glucose concentration and nitrogen source, culture time also had a signi cant effect on lipid accumulation.…”

“…Urea [18,26], ammonium [27,28], nitrite [29]and nitrate [30] were found to produce highest biomass and lipid production in various Chlorella species. Whereas, nitrate was found as the best nitrogen source for both growth and lipid production in other microalgae [31][32][33][34][35][36]. In general, decreased N source concentration reduces the biomass productivity and increases lipid content which is due to reduced metabolism rate resulted in channeling of excess carbon towards storage molecules production such as triacylglycerides.…”
