Özet
<p>The filamentous cyanobacterium Spirulina (Arthrospira) is produced commercially all over the world. And dried Spirulina biomass product is a valuable food supplement, feed and is used as a food coloring and additive. In this study, Spirulina was grown in open raceway ponds in Aegean Region (Aydın-Turkey), and several physicochemical (e.g., temperature, pH, dissolved oxygen concentration, conductivity and irradiance) and biological (e.g., biomass concentration and yield) variables were studied. Dissolved oxygen concentration in the cultivation ponds ranged between 10mgl−1 in winter (110% of O2 saturation) and 30mgl−1 in summer (230% of O2 saturation); a clear decrease of biomass concentration was found when dissolved oxygen was >20mgl−1. Neither biomass concentration nor productivity was saturated at the maximum</p><p>temperature achieved in the open pond during this study (approx imately 32 ◦C). The pH seemed to control both the maximal algal</p><p>density in the pond and the productivity that were found to be maximum at pH values below 11.</p>
