“…This was not surprising given that cyanobacteria have the great adaptability to variations in environmental factors. Other authors have reported the use of Spirulina grown on Zarrouk's medium in wastewater treatment (Mezzomo et al 2010, Amala and Ramanathan 2013, Chaiklahan et al 2013, Ismail et al 2013. Indeed, monoculture tanks were more productive than the tanks seeded with a diverse assemblage of algae.…”

Planktivorous fish which limit zooplankton grazing have been predicted to increase algal biodiesel production in wastewater fed open reactors. In addition, tanks with higher algal diversity have been predicted to be more stable, more productive, and to more fully remove nutrients from wastewater. To test these predictions, we conducted a 14-week experiment in Houston, TX using twelve 2,270-L open tanks continuously supplied with wastewater. Tanks received algal composition (monocultures or diverse assemblage) and trophic (fish or no fish) treatments in a full-factorial design. Monocultures produced more algal and fatty acid methyl ester (FAME) mass than diverse tanks. More than 80% of lipids were converted to FAME indicating potentially high production for conversion to biodiesel (up to 0.9 T ha -1 y -1). Prolific algal growth lowered temperature and levels of total dissolved solids in the tanks and increased pH and dissolved oxygen compared to supply water. Algae in the tanks removed 91% of nitrate-N and 53% of phosphorus from wastewater. Monocultures were not invaded by other algal species. Fish did not affect any variables. Our results indicated that algae can be grown in open tank bioreactors using wastewater as a nutrient source. The stable productivity of monocultures suggests that this may be a viable production method to procure algal biomass for biodiesel production.

“…NaHCO 3 at 2% (v/v) of anaerobic effluent (Olguín et al, 2001), 4.5 g L -1 of NaHCO 3 in 20% (v/v) of anaerobic effluent (Chaiklahan et al, 2010), 4-10 g L -1 of NaHCO 3 at concentrations of 0 to 100% (v/v) of anaerobic effluent, with the best results found with 8 g L -1 of NaHCO 3 and 10% (v/v) of effluent (Cheunbarn and Peerapornpisal, 2010). But Radmann et al (2007) and found higher yields for this microalga in diluted culture media, which creates the possibility of testing lower concentrations of carbon to complement the culture medium with effluent.…”

-The carbon source is the most expensive nutrient for Spirulina production; effluents from anaerobic digestion contain this nutrient in the form of HCO 3 -. The aim of this study was to assess the growth kinetics, composition and fatty acid profile of Spirulina sp. LEB-18 grown in standard Zarrouk medium (NaHCO 3 16.8 g L -1) and in Zarrouk medium replaced with 20% (v/v) effluent with reduced concentrations of NaHCO 3 (5.3 and 2.8 g L -1 ). The use of effluent and lower concentrations of HCO 3 -was found to be an alternative to reduce the costs of Spirulina production, because there were no significant differences in growth parameters (μ max 0.324 -0.354 d -1 ; P max 0.280 -0.297 g L -1 d -1 ), in the different culture medium used. Lipids ranged between 4.9 and 5.0%; the media with effluent had higher levels of linoleic acid compared to the standard medium.

“…En la última década variados sustratos y diferentes estrategias de cultivo han sido evaluados con el fin de mejorar procesos biotecnológicos del cultivo de A. platensis, por lo que se ha evaluado su crecimiento en diferentes sustratos tales como aguas residuales porcinas (Chaiklahan et al, 2010), orina humana diluida (Feng y Wu, 2006), melaza (Andrade y Costa, 2007), gallinaza (Ungsethaphand, 2009), AIA comercial el cual demostró ser un eficaz estimulante de crecimiento (Munawer y Mazharuddin, 2011;Gómez, et al, 2012) y reguladores comerciales de crecimiento vegetal hecho a base de carbón (Prakash et al, 2011). Pero muchas veces no se logra la productividad deseada debido a que algunos de estos insumos y sustratos para su cultivo presentan elevados costos, requieren pre-tratamientos para su utilización, contienen elementos químicos tóxicos que pueden biomagnificarse en la biomasa algal resultante y requieren condiciones especiales para su utilización (Munawer y Mazharuddin, 2011), por lo que su uso es poco viable desde un punto de vista de seguridad, económico y técnico.…”

ResumenLa producción de biomasa y pigmentos a partir de Arthrospira platensis ha cobrado gran importancia, debido a que estos tienen aplicaciones en producción de alimentos, metabolitos de interés biotecnológico e industrial. No obstante, para la producción de biomasa y pigmentos se han utilizado diversos sustratos que generan altos costos. Se estudió el crecimiento y producción de pigmentos de A. platensis bajo la influencia de seis concentraciones de carbón de bajo rango (CBR) tipo lignito (10, 20, 30, 40, 50, 60 mg/L) frente a una concentración de AIA (80 mg/L), se realizaron cultivos en batch en medio Zarrouk suplementados con CBR tipo lignito y AIA, bajo condiciones de aireación constante y fotoperiodos de 12:12 horas, durante 33 días. Los valores promedios más altos que se obtuvieron en cuanto a producción de biomasa y pigmentos se lograron en los cultivos suplementados con 50 y 60 mg/L de CBR tipo lignito con respecto a los controles. Los resultados obtenidos dan constancia al uso potencial del CBR como materia orgánica humificada, rica en nutrientes para el cultivo A. platensis que podrían ser aprovechado en medios acuíferos que son expuestos a la explotación carbonífera, contribuyendo a procesos de depuración y biorremediación de aguas contaminadas con materiales carboníferos.Palabras clave: carbón tipo lignito, pigmentos, solubilización, tasa de crecimiento. AbstractThe Biomass production and pigments from Arthrospira platensis has become very important, because these have applications in food production, metabolites of biotechnological and industrial products. However, for the production of biomass and pigments they have been used various substrates that generate high costs. Growth and pigment production A. platensis under the influence of six concentrations of low rank coal (LRC) type lignite (10, 20, 30, 40, 50, 60 mg / L) was tested against a concentration of AIA (80 mg / L), in batch cultures, performed in Zarrouk medium supplemented with LRC type lignite and AIA, under constant aeration and photoperiod of 12:12 hours, for 33 days. The highest average values obtained in terms of biomass production and pigments were achieved in the cultures supplemented with 50 and 60 mg/L of LRC type lignite with respect to the controls. The results provide evidence of the potential use of CBR as humified organic matter, rich in nutrients for growing A. platensis that could be tapped into aquifers means they are exposed to coal mining, contributing to processes of purification and bioremediation of contaminated waters carboniferous materials.
