This study has presented the assessment of carbon dioxide bioremediation rate, growth kinetics, and protein content of the Scenedesmus obliquus, Monoraphidium contortum, Psammothidium sp, and Chlorella vulgaris species, which are supplying with 0.04 % and 10 % carbon dioxide concentration in the different types of photobioreactor (glass flask and tubular vertical column). This experiment showed the growth parameters for all of the microalgae species significantly increased when fed 10 % carbon dioxide compared to those fed 0.04 % carbon dioxide in either type of PBR. Maximum growth kinetics were observed in Chlorella vulgaris when it was grown in 10 % CO2 in the tubular vertical column PBR with 2.12 g L-1 (X-max), 0.61 g L-1 d(-1) (P-max), 11.07 g d(-1) (R-C), 51.59 % (wt.%), and 42.75 % (Overall CR%). In addition, we observed a maximum protein content at Chlorella vulgaris (72.12 %) by cultivation in glass flask PBR with 10 % CO2.
