A novel two-stage experimental photobioreactor, based uniquely on solar concentrators - linear Fresnel lenses, has been constructed and tested. Daily courses of irradiance were measured in two unit types. The supra-high irradiance units in the roof achieved a maximum summer value above 6 mmol photon m-2 s-1, while irradiance in the vertical-facade units was lower than ambient. In model cultivations, cultures of the cyanobacterium Arthrospira platensis were cultivated at much higher solar irradiances than those usually recorded outdoors in summer, indicating that this organism is resilient to high-irradiance (photoinhibition). A two-stage cultivation process of the green microalga Haematococcus pluvialis was studied with respect to correlations between photochemical activities and astaxanthin production
