Meireles, Luís A.; Guedes, A. Catarina; Barbosa, Catarina R.; Azevedo, José L.; Cunha, João P.; Malcata, F. XavierThe influence of light intensity upon biomass and fatty acid productivity by the microalga Pavlova lutheri was experimentally studied using a novel device. This device was designed to automatically adjust light intensity in a photobioreactor: it takes on-line measurements of biomass concentration, and was successfully tested to implement a feedback control of light based on the growth rate variation. Using said...
On-Line Determination of Biomass in a Microalga Bioreactor Using a novel Comput...
Meireles, Luís A.; Azevedo, José L.; Cunha, João P.; Malcata, F. XavierA flow injection analysis (FIA) device has been developed, which is able to assay successfully for biomass in a microalga bioreactor. The device is fully computerized and is operated via diluting small aliquots of the culture followed by measuring optical density (OD); this figure is then accurately correlated with biomass, in terms of both cell number and ash-free dry weight, during the entire culture time. Fu...
