NaCl as an effective inducer for lipid accumulation in freshwater microalgae Desmodesmus abundans

Rapid neutral lipid accumulation of the alkali-resistant oleaginous Monoraphidium dybowskii LB50 by NaCl induction

“…The effectiveness of this type of inducer mainly depends on the use of iron salt, zinc salt, and sodium salt (NaCl, NaHCO 3 , NaAC) etc. (Einicker-Lamas et al, 2002;Herrera-Valencia et al, 2011;Liu et al, 2008;Xia et al, 2013Xia et al, , 2014. However, the effects are not evident in numerous microalgae strains when iron salt and zinc salt are used for induction.…”

Physiological responses of freshwater oleaginous microalgae Desmodesmus sp. NMX451 under nitrogen deficiency and alkaline pH-induced lipid accumulation

“…To ensure well mixed medium, we used a 5 cm magnetic stir bar (mixing at 150 rpm) placed at the middle of the bioreactor chamber for stirring. Air was bubbled in bioreactors at a constant rate (Xia et al 2013(Xia et al , 2014 on the surface of the bioreactor.…”

Selection of microalgae for biodiesel production in a scalable outdoor photobioreactor in north China

“…All experiments were conducted in bioreactors (5 L flask bioreactor or 140 L airlift bag columns) as described previously by Xia et al (2013Xia et al ( , 2014 in the green house in Beijing, China (40°22 0 N, 116°20 0 E). For strain selection, the cultures were grown in 5 L Erlenmeyer flask (0.37 m height  0.22 m in diameter) with 3 L medium.…”

“…and soybean (Table 3). However, biodiesel property of D. abundans T12 can be improved when subjected to high salt or high alkaline (Xia et al, 2014). The CN is a prime indicator of biodiesel quality, and related to the ignition delay time and combustion quality.…”

“…, and culture media was BG-11 with nitrogen source of only 0.2 g L À1 urea because urea is significantly less expensive and exhibited more favorable effect on algal growth in outdoor cultures (Xia et al, 2013(Xia et al, , 2014. The average day time high and night time low air temperatures during the tested period were 39°C and 23°C.…”
