Abstract:
Microalgae are a potential source of renewable energy due to their fast growth, high content of lipid, coupled with no requirement of fertile land. The deposition of nitrogen compounds favours the microalgae growth, and their excess in ponds develops the process of eutrophication. The industries should follow emission limits of these compounds determined by their environmental agency. Many researchers have been studying the use of wastewaters to cultivate microalgae. The purpose of this paper is to test the viability of the use of a wastewater with high levels of ammonia from a fertilizer industry in Brazil in the production of the microalgae Chlorella sp.. The toxicity test showed the viability of the use of this effluent in concentrations close to 10% (v/v) for Chlorella sp. The growth of Chlorella in wastewater medium was investigated for 12 days. The results showed a better increase in biomass of wastewater culture medium than the control culture medium. The maximum cell concentration of 9.5 x 106 cells/ml was obtained in wastewater culture medium. This study shows that it is possible to use this effluent as an alternative culture medium for these microalgae.
