Fig. 3

The absolute bacterial abundance based on 16S rRNA copies in unsterilized piggery wastewater. CA means sparging air, CC means sparging simulated flue gas, PA means culturing C. pyrenoidosa with sparging air, and PC means culturing C. pyrenoidosa with sparging simulated flue gas. Data are presented as the mean ± standard deviation of the mean. The different letters indicate that there was a significant difference with P < 0.05
