Model performance of partial least squares in utilizing the visible spectroscopy data for estimation of algal biomass in a photobioreactor

2018

[EN] Spectroscopy technology and statistical methods (Partial Least Squares) have been integrated to develop a model that allows estimating the microalgal biomass in a photobioreactor. The model employing PLS combines the absorption spectrum measurements in the visible range (400-750 nm) with a microalgae cell density in a water sample. First, a calibration model was constructed using a calibration data set, and then, the predictive capacity of the model was determined by cross validation. Finally, an external validation of the predictive performance of the model was carried out with an independent data set. To test the accuracy of the model it was applied to different culture conditions yi…

The proitability of microalgae biomass farming in Mediterranean environments

2015

The aims of the present study was to assess the economic sustainability of microalgae cultivation in PBRs, ascertain in what conditions of productivity and price it is possible to achieve similar results to those of the irst case, and assess the impact that the results of plant management could have on the balance sheets of farms which may have an interest in expanding their production. Our results show shows that, while prospects are encouraging, there is a need to develop structured supply chains able to confer greater stability to the market and to ensure a higher degree of certainty to stakeholders.
