Chlorella strains were screened which are nitrite-tolerant, and an efficient bioreactor was developed. After a stepwise optimization of mixotrophic cultivation of Chlorella using actual flue gas fixed salts (FGFS), an impressive DeNOx efficiency of over 96%, along with a biomass productivity of 9.87 g L-1 d-1 and a significantly high bio-lipid productivity of 1.83 g L-1 d-1, were obtained.
