Abstract: RESUMO -Três espécies de algas clorofíceas, Scenedesmus quadricauda (Brèbisson, 1835), Ankistrodesmus gracilis (Korsikov, 1953) e Pediastrum duplex (Meyen, 1829), foram cultivadas no laboratório, usando como meio de cultura adubo químico N: P: K. na proporção 20:5:20, respectivamente. O valor nutricional das algas foi avaliado pela concentração de clorofila-a e pelo carbono orgânico. As três espécies algais apresentaram alto valor nutricional, particularmente Scenedesmus quadricauda, que apresentou a maior pe… Show more

“…In Brazil, few studies have emphasized plankton development and its nutritive value (Rocha & Matsumura-Tundisi, 1990;Hardy & Duncan, 1994;Sipaúba-Tavares et al, 1994;Hardy & Castro, 2000;Macedo & Pinto-Coelho, 2000).…”

“…The growth in the T1 and T2 treatments, however, peaked between day 3 and 6, whereas growth in the T2 treatment also peaked between day 12 and 15 ( Figure 4). Hardy and Castro (2000) also observed a peak in the growth of Chlorophyceae Scenedesmus quadricauda between day 5 and 7, with a trend of better growth in the medium NPK.…”

“…Among the different applications and encouragement of the production of microalgae in Brazil, feeding plankton and fish larvae are the best known (HARDY; CASTRO, 2000;SIPAÚBA-TAVARES et al, 2009). These microorganisms may also serve multiple functions in biotechnological studies, such as bioremediation of metals and other pollutants, toxicology testing (MOREIRA-SANTOS et al, 2004), solar energy bioconservation (energy storage), ingredients for feed, fermentation (methane production), extraction of various products such as pigments and algins ROCHA, 2003), biodiesel production, and food supplementation.…”

“…O cultivo foi realizado na diluição de 30% de vinhaça, em triplicata, tendo como controle e padrão de comparação o adubo químico N:P:K (0,02:0,005:0,02 kg L -1 ) (HARDY & CASTRO, 2000;SIPAUBA-TAVARES & ROCHA, 2003;SIPAUBA-TAVARES & PEREIRA, 2008;CARVALHO et al, 2012) na concentração de 1%, também em triplicata. Esta fonte de nutriente foi escolhida em função de ser o adubo químico utilizado no cultivo da cana-deaçúcar.…”
