Bioprocessos para remoção de dióxido de carbono e óxido de nitrogênio por micro-algas visando a utilização de gases gerados durante a combustão do carvão

Abstract: . The aim of this work was to study the removal of CO 2 and NO by microalgae and to evaluate the kinetic characteristics of the cultures. Spirulina sp. showed μ max and X max (0.11 d -1 ) when treated with CO 2 and NaNO 3 . The maximum CO 2 removal was 22.97% for S. obliquus treated with KNO 3 and atmospheric CO 2 . The S. obliquus showed maximum NO removal (21.30%) when treated with NO and CO 2 . Coupling the cultivation of these microalgae with the removal of CO 2 and NO has the potential not only to reduce … Show more

“…wastewater and CO 2 from the exhaust of power plants). [1,2,16,17] Microalgae are an option for wastewater treatment involving bioremediation promoted by open systems such as high rate algal ponds or by closed systems such as photobioreactors, combining microalgae production with wastewater treatment. [18] In this context, this study aimed to construct and operate a tubular photobioreactor for the cultivation of the microalgae Desmodesmus subspicatus (R. Chodat, E. Hegewald and A. Schmidt (Chlorophyta)) grown in effluent from the wastewater treatment plant of the University of Santa Cruz 210 P.D.…”

“…A microalga Spirulina sp. LEB 18 (MORAIS et al, 2008), foi cultivada em meio Zarrouk, contendo (g L -1 ): NaHCO 3 , 16,8; NaNO 3 , 2,5; K 2 HPO 4 , 0,5; K 2 SO 4 , 1,0; NaCl, 1,0; Mg.SO 4 .7H 2 O, 0,2; CaCl 2 , 0,04; FeSO 4 .7H 2 O, 0,01; EDTA, 0,08 e micronutrientes. Neste experimento, a fonte de nitrogênio foi reduzida em 50% e a fonte de carbono foi substituída por CO 2 comercial a 10% (v/v) em uma mistura com ar a 90 mL mistura /min.…”

“…Cyanobacteria are used for various purposes, e.g., for food supplements for humans [3] and animals [4] . Some cultures are used in wastewater treatment [5] , in fixing carbon dioxide and in biocompound synthesis [6,7] . The biomass of Spirulina has been investigated for its hypocholesterolemic potential [8] , as a source of biofuels [9] and for biopolymer production [10][11][12] .…”
