A comparison of productivity, protein and lipid content of spirulina platensis in cultured in pond and photobioreactors

Dry matter, chlorophyll a, cell density, protein and lipid production of microalgae Spirulina platensis culured in tubular and panel photobioreactors, pond in June and September were compaired. The highest dry matter of 4.951±0.03 gL-1 and 71.89±1% protein were determined from tubular photobioreactor, while the lowest dry matter of 2.710±0.02 gL-1 and 53.92±0.8% protein were recorded from panel photobioreactor. S. platensis cultured in the pond have 3.150±0.08 gL-1 dry matter and 70,29±0,8% protein. The water temperatures in June and September were similar, and it was observed that the culture in the panel was affected negative to the higher temperature (39.35±1.82 °C, 40.22±0.70 °C). The highest optic density (3.280±0.009), lipid (7.74±0.5%) and chlorophyll a (510.1±6 ?gL-1) amounts were obtained from the culture produced in the tubular photobioreactors.
