Influence of nitrogen sources on biomass productivity of microalgae Scenedesmus bijugatus

Cultivation of freshwater microalga <i>Scenedesmus</i> sp. using a low-cost inorganic fertilizer for enhanced biomass and lipid yield

“…to be the most significant for microalgae growth (Arumugam et al, 2013;Goswami and Kalita, 2011;Makareviciene et al, 2011). We are of the opinion that the combination of a NPK fertilizer with urea, in a potable tap water medium, effectively supplied the nutritional requirement for microalgae Scenedesmus sp.…”

Optimizing light regimes on growth and lipid accumulation in Ankistrodesmus fusiformis H1 for biodiesel production

“…1, the biomass of A. fusiformis H1 exhibited a steady increase with the nitrogen concentration from 0 to 8.93 mM, thereafter leading to a slightly decrease, regardless of the nitrogen source. The retardation may be the inhibitive effect caused by high nitrogen concentrations (Li et al, 2008;Arumugam et al, 2013;He et al, 2015a). Under nitrogenstarvation condition (0 mM), the lipid content (46.78%) was much higher than other treatments (Table 1).…”

Influence of culture media and carbon sources on biomass productivityand oil content of the algae Sirogonium sticticum, Temnogyra reflexa,Uronema elongatum, and Chroococcus turgidus

“…Previous studies have demonstrated that the biomass and lipid content in some microalgae were affected by various cultivation conditions such as nitrogen supply and its sources (Li et al, 2008;Arumugam et al, 2013), salt concentration (Takagi et al, 2006), level of CO 2 (Chinnasamy et al, 2009), light intensity, and temperature (Renaud et al, 2002;Khotimchenko and Yakovleva, 2005;Juneja et al, 2013). These observations allowed us to hypothesize that there might be a profound effect of media type and carbon sources on the biomass and oil content of the microalgae S. sticticum, T. reflexa, U. elongatum, and C. turgidus.…”
