“…Among metal-ions sequestering organisms, microalgae were found to effectively bind metal ions from solutions [17] . As it was shown previously, mixotrophic [18] blue-green alga Spirulina sp. was a very good biosorbent of metal ions, Cr(III), Cd(II) and Cu(II) from model solutions [19] .…”

Abstract:The paper presents the results of studies on kinetics and equilibrium of bioaccumulation process of Cr(III) ions by blue-green alga Spirulina sp. Bioaccumulation was described as the process that consists of two stages, passive (identical with biosorption) and active (accumulation inside the cells). The passive stage (similarly as biosorption itself) was found to be quick process and the subsequent active stage (accumulation) was much slower and required metabolic activity of cells. The overall equilibrium of bioaccumulation process was reached after ca. 30 hours. The efficiency of bioaccumulation was compared with biosorption performance of cells grown under the same conditions. Two applications of bioaccumulation were discussed: metal ions removal from wastewater and metal ions binding to the biomass to produce biological feed supplement with microelements. The experimental results showed that bioaccumulation capacity was greater than biosorption capacity. Wastewater treated by the process of bioaccumulation contained lower residual metal ions concentration due to equilibrium shift of external (biosorptive) metal ions binding capacity towards lower values, resulting in lower residual metal ions concentration and thus higher treatment efficiencies. If bioaccumulation was considered as the method of biomass enrichment to produce mineral feed supplements for livestock, bioaccumulation enabled to bind more microelements, not only to the surface of cell wall, but also to accumulate inside the cells.

“…When Spirulina sp. Growth in photoautotrophic, heterotrophic and mixotrophic cultures were compared, it was found that mixotrophic culture improved growth rate over both autotrophic and heterotrophic cultures (Chojnacka and Noworyta 2004). In Chlorella vulgaris, mixotrophic culture with 1.0 percent glucose showed the highest lipid productivity compared to other growth conditions (Liang et al 2009).…”

“…Temperatura promedio de cultivo e irradiancia, registrada para todo el cultivo continuo C1, C2 y C3. & Zhang, 1997;Chojnacka & Noworyta, 2004;Muliterno et al, 2005). Algunos autores (Chen & Zhang, 1997;Andrade & Costa, 2007) han encontrado que en los primeros días de cultivo de A. platensis, se presenta una fase heterotrófica dominante, que a medida en que los nutrientes (en este caso, glucosa como fuente de carbono) son consumidos, disminuye, dominando la fase fotoautrófica en una segunda etapa.…”

“…Por otra parte, Chojnacka & Noworyta (2004) encontraron que Spirulina, es capaz de crecer en condiciones de luz (fotoautotróficamente), en base a fuentes de carbono (glucosa) orgánico (heterotróficamente) y mixotró-ficamente (luz y glucosa). Dhiab et al (2010) observaron que A. platensis crece en presencia de sustrato orgánico, independientemente de la intensidad de luz y concentración de glucosa, demostrando dos fases diferentes en las tasas instantáneas de crecimiento relativo, en la fotosíntesis neta y tasa de respiración oscura, tanto en cultivos autotróficos como en mixotróficos, caracterizándose por una preponderancia de la actividad fotosintética (aumento en el pH).…”

Aplicación de estrategias nutricionales y su efecto en el crecimiento en el cultivo continuo de Spirulina (Arthrospira platensis) RESUMEN. Se realizó un cultivo continuo de Spirulina (Arthrospira platensis) durante 78 días en un fotobiorreactor tubular de 300 L de volumen. Durante este periodo se registró el crecimiento en biomasa y la respuesta del cultivo a la estrategia de adición del medio nutritivo. Utilizando como base el medio Zarrouk modificado, se elaboraron tres medios: medio inicial (MI), medio crecimiento (SA1+SA2) y medio mantenimiento (SB1+SB2) para las distintas etapas del cultivo. La entrega de los medios se efectuó paulatinamente y de acuerdo a los requerimientos del crecimiento en biomasa (en peso seco) diario del cultivo. La biomasa inicial del cultivo fue de 2,0 g L -1, al día 20 se efectuó la primera cosecha parcial (50%) dando inicio a una nueva etapa del cultivo con una biomasa inicial de 1,7 g L -1 , 20 días después se realizó una segunda cosecha parcial del cultivo, iniciando una tercera etapa de cultivo con una biomasa de 1,6 g L -1 . Los resultados obtenidos al cabo de las cosechas fueron, en promedio, de 3,7; 4,1 y 9,7 g L -1 , respectivamente. El análisis proximal efectuado al final del cultivo continuo indicó un 71,6% de proteína. Palabras clave: Arthrospira platensis, Spirulina, medio nutritivo, crecimiento, cultivo, Chile. Application of nutritional strategies and their effect in continuous culture of Spirulina (Arthrospira platensis)ABSTRACT. A continuous culture of Spirulina (Arthrospira platensis) was performed for 78 in a tubular photobioreactor of 300 L volume. During this period there was growth in biomass and crop response to the strategy of adding the nutrient medium. Using as a basis the modified Zarrouk medium, three nutritive combinations were elaborated: initial medium (MI), growth medium (SA1+SA2) and maintenance medium (SB1+SB2) for different crop stages. The media delivery is affected gradually and in accordance with requirements of growing biomass (dry weight) daily cultivation. The initial crop biomass was 2.0 g L -1, on day 20 of culture was made the first partial harvest (50%) starting a new stage of the crop with an initial biomass of 1.7 g L -1, 20 days after a second crop was partially culture initiating a third culture step with a biomass of 1.6 g L -1 . The results obtained after harvest were, on the average, 3.7; 4.1 and 9.7 g L -1 respectively. The proximal analysis was performed at the end of the continuous cultivation showed a 71.6% of protein content. Keywords: Arthrospira platensis, Spirulina, nutrient medium, growth, culture, Chile. ___________________Corresponding author: Elizabet Rojas (elizabet.rojas@cordunap.cl) INTRODUCCIÓNLa especie Arthrospira platensis, conocida como Spirulina, es una cianobacteria, capaz de convertir la energía del sol en compuestos químicos usando dióxido de carbono y liberando oxígeno.
