Article:

O objetivo foi produzir Spirulina sp. (LEB 18) biomassa pela reutilização e tratamento de águas residuárias da aquicultura, determinando o melhor desempenho produtivo através de parâmetros cinéticos. Os cultivos foram realizados em fotobiorreatores (1L) com 100% de água residual de aquicultura suplementada com T-25, T-50, T-75. Não houve diferença significativa na concentração de biomassa nos tratamentos 50% (1,02 gL-1), 25% (1,10 gL-1) e controle (1,05 gL-1). Assim, o tratamento com 25% representa uma alternativa eficiente, barata e sustentável para o setor de aquicultura, reduzindo os impactos das descargas de efluentes, produzindo biomassa de baixo custo com características diferenciadas e alto valor agregado.

The objective was to produce Spirulina sp. (LEB 18) biomass by reuse and treatment of aquaculture wastewater, determining the best productive performance through kinetic parameters. Cultures were performed in photobioreactors (1L) with 100% residual aquaculture water supplemented with T-25, T-50, T-75. There was no significant difference in biomass concentration in the 50% (1.02 gL-1), 25% (1.10 gL-1) and control (1.05 gL-1) treatments. Thus, the 25% treatment represents an efficient, cheap and sustainable alternative for the aquaculture sector, reducing the impacts of effluent discharges, producing low cost biomass with different characteristics and high added value.
