Utilization of simulated flue gas for cultivation of Scenedesmus dimorphus

Mixotrophic cultivation of a microalga Scenedesmus obliquus in municipal wastewater supplemented with food wastewater and flue gas CO 2 for biomass production

“…Exhaust flue-gases with high concentrations of CO 2 (~15%, v/v) that are released from different industrial sectors including thermal power, cement, steel and incineration, can be used as an economical CO 2 source for photosynthetic microalgal biomass production (Chiu et al, 2011;Praveenkumar et al, 2014a). However, NO x , SO x and H 2 S, and particulate matters in flue gas can cause acidification to the medium and pose environmental stress to algae (Chiu et al, 2011;Jiang et al, 2013;Kumar et al, 2014). Therefore, microalgal species tolerant to industrial flue gas should be secured for effective microalgae biomass production; few microalgal species such as Chlorella sp., Scenedesmus dimorphus have been identified to sustain and grow in the presence flue gas (Kumar et al, 2014;Praveenkumar et al, 2014a).…”

Baltic Sea microalgae transform cement flue gas into valuable biomass

“…Microalgae show a good growth potential in CO 2 concentrations up to 10-20% regardless of the source, e.g. pure CO 2 [13,14] and industrial flue gas [15][16][17]6,18,8]. Industrial flue gas contains over 100 substances, of which several are potentially toxic to microalgae (e.g.…”

Current Status and Outlook in the Application of Microalgae in Biodiesel Production and Environmental Protection

“…Yang et al (2004) reported low concentrations of bisulfite (0-1 mmol/L) had no adverse influence on the growth of B. braunii, but bisulfite was toxic at high concentrations (>1 mmol/L). However, Scenedesmus dimorphus grew well (3.20 g/L) with simulated flue gas (15% CO 2 , 400 ppm SO 2 , 300 ppm NO, balance N 2 ) (Jiang et al, 2013). To better engineer flue gas-fed microalgal cultures, the effects of all flue gas compounds, tolerance of various microalgae to flue gas compounds, and the interaction of flue gas compounds and microalgae need to be assessed (de-Bashan and Bashan, 2010;Van den Hende et al, 2012).…”
