Phycocyanin production in seawater culture of Arthrospira maxima

Phycocyanin production in seawater culture of Arthrospira maxima

 Three seawater-based media were used for biomass and phycocyanin production by Arthrospira maxima. Among the three seawater-based media, growth rate and biomass were lowest in SWMAB, which is identical to SWM but includes several known essential elements (Zn, Cu, Mo, Mn). Growth in SWMX2,...

The phycocyanin produced in the seawater-based media had slightly different absorption and fluorescence maxima compared to those of A.platensis. Tres medios de cultivo preparados en agua de mar fueron usados para la producción de biomasa y ficocianina por Arthrospira maxima. Entre los tres medios preparados en agua de mar, la tasa de crecimiento y la biomasa fueron los más bajos en SWMAB, el cual es idéntico a SWM, pero incluye varios elementos esenciales conocidos (Zn, Cu, Mo, Mn). El crecimiento en SWMX2, el cual tiene el doble de concentración de NaHCO3, N, P y FeEDTA que SWM, no fue significativamente diferente para estos dos medios. Arthrospira maxima alcanza una concentración de biomasa de 2.7 ± 0.06 g L–1 en un medio mineral estándar, pero <1.2 ± 0.09 g L–1 en los medios preparados en agua de mar. El contenido de pigmentos en células crecidas en los medios preparados en agua de mar fue de <2.78 ± 0.46, < 1.85 ± 0.184 y <19.83 ± 3.16 mg g–1 células para clorofila a, carotenoides y ficocianina, respectivamente. La ficocianina producida en los medios preparados en agua de mar mostró leves diferencias en sus propiedades espectrales de absorción y fluorescencia máxima comparadas con las de A.platensis.
