Abstract

SOUSA, Louise Lins de; HORA, Dominique Silveira da; SALES, Emerson Andrade  and  PERELO, Louisa Wessels. Cultivation of Nannochloropsis sp. in brackish groundwater supplemented with municipal wastewater as a nutrient source. Braz. arch. biol. technol. [online]. 2014, vol.57, n.2, pp.171-177. ISSN 1516-8913.  http://dx.doi.org/10.1590/S1516-89132014000200003.

The aim of this work was to study growth potential of the green microalgae Nannochloropsis sp. using brackish groundwater from a well in the semi-arid northeast region of Brazil as culture medium. The medium was supplemented with (%) 19.4, 22.0, 44.0 and 50.0% of municipal wastewater after UASB treatment as a low-cost nutrient source. The results showed that the culture tested was capable of growing in the brackish groundwater even at salinity levels as low as 2 ppt. Furthermore it was shown that municipal wastewater could be used as a sole nutrient source for Nannochloropsis sp.

Keywords : Microalgae; brackish groundwater; municipal wastewater; Nannochloropsis sp.
