Cultivation of Arthrospira platensis (Spirulina) in curved doubly tubular photobioreactor to environmental conditions in the South of the Peru

Abstract

The present work investigated the cultivation of microalgae Arthrospira platensis (Spirulina) in productivity values cultivated in doubly curved tubular photobioreactor to environmental conditions in order to take advantage of the high solar radiation of the Arequipa region in southern Peru (16°24´50´´ LS; 71°32´02´´LW; 2344 msnm.). The photobioreactor was built with a transparent tube of polyvinyl chloride (PVC). The productivity of the crop was 13.9 g/m2 in 14 days or 1 g/m2/day and a concentration of chlorophyll - "a" 0.00785 mg/L with a maximum radiation of 1179 W/m2, and a 121500 lux illumination, making its helical filaments abnormal morphologies, such as curves and linear even irregular shapes with fragmentation, demonstrating that the crop was affected by high radiation and variations in temperatures of Arequipa.
