Abstract

This work aimed to evaluate the growth and cost cultivation of Chlorella sp microalgae in PA and commercial urea medium solutions compared to BBM standard medium. We cultivated the microalgae Chlorella sp in BBM, PA urea, and commercial urea media, evaluating their growth for 8 days. In addition, we appraised the cost of the culture media considering the quotation of the reagents and the mass used for pilot-scale cultivation (100l). It was possible to observe the similar growth of microalgae with urea PA and BBM. The use of urea PA as a culture media for microalgae has the potential to reduce the cost of the medium by 68%. Thus, the cultivation of Chlorella in urea medium represents an alternative to reduce the production costs of biomass from this microorganism.
