Fig. 7From: A recycling culture of Neochloris oleoabundans in a bicarbonate-based integrated carbon capture and algae production system with harvesting by auto-flocculationA recycling culture of Neochloris oleoabundans with semi-continuous mode. a Biomass concentration, b pH change (spent medium bubbled CO2 to adjust pH and supply carbon). Arrows mean that the nutrients were added to the recycling culture at the 8th and 14th day, while the lines with asterisk and rhombus represents the pH* of 0.1 and 0.3 mol L−1 bicarbonate, respectively. Values are the mean ± SD of three independent measurementsBack to article page
