Valorization of wastewaters via bioenergy and bioproducts using carbohydrates from microalgae

Abstract

The use of whole fractions after the pretreatment improve the sugar yields of the next steps and, hence, low residues are generated. Chemical pretreatments applied have a disinfectant effect and at low concentrations report the best results in all the steps. The work concludes different feasible possibilities to use the whole fractions. The enzymatic hydrolysis at shorter times (<6h) achieve the maximum sugar recovery with the minimum degradation. The production of biogas and biofertilizers is the other alternative that chemical pretreatments enhance respect the untreated biomass.
