| Abstract: | The variations in culture conditions (irradiance, temperature, pH and dissolved oxygen) in a thin-layer 120 m2 surface reactor have been studied, both in terms of position inside the reactor and time of the daylight cycle. Results demonstrate that average irradiance and temperature to which the cells are exposed are mainly a function of time, whereas pH and dissolved oxygen concentrations also showed relevant gradients depending on their position inside the reactor. The existence of gradients has been demonstrated to reduce the culture performance, using both chlorophyll-fluorescence and net photosynthesis rate methods. Moreover, the influence of culture conditions on Scenedesmus almeriensis cell performance was modelled. The obtained model allows us to quantify the loss in productivity caused by inadequate culture conditions; the net photosynthesis rate being demonstrated as only 32% of the maximal achievable. This is the first step in optimizing and scaling-up this type of reactor for industrial applications. |
