SALAS-HERRERA, Gerardo et al. Evaluation of microalgae for the production of economically useful biomass using produced water. Rev. Mex. Cienc. Agríc [online]. 2015, vol.6, n.spe12, pp.2423-2435. ISSN 2007-0934.

The production of microalgae for biodiesel and other valuable products is a topic devoting great efforts. However, microalgae production requires large volumes of water and for its sustainable production requires searching for other water sources that do not compete with food production. In this sense produced water generated from the oil industry could be an alternative source of water, so for the present study the adaptation and growth of three microalgae strains halotolerant in two sources of produced water at the Sabinas basin Northeast Mexico were evaluated. It was found that one of the sources of produced water, in the Monclova 1 station, has potential for exploitation using microalgae Nannochloropsis sp. which showed greater adaptability to this water being a good candidate for further research. Moreover, I. galbana did not tolerate the presence of produced water in the medium; however, when treatments were planted again showed a positive population growth response, showing with this the bioremediation ability of this strain.

Keywords : Dunaliella; Isochrysis; Nannochloropsis; biodisel; bioremediation.
