Synthesis of dietetic structures lipids from spent coffee grounds crude oil cat...
Mota, Danyelle A.; Santos, Jefferson C.B.; Faria, Diana; Lima, Álvaro S.; Krauze, Laiza C.; Soares, Cleide M.F.; Ferreira-Dias, SuzanaThe aim of this study was the valorization of coffee industry residues, namely spent coffee grounds (SCG) as a source of oil, and silverskin (CS) as a source of both oil and biomass, under the concept of the circular economy. Therefore, crude oil from SCG was used to produce low-calorie structured lipids (SL) for food and pharmaceutical industries, and CS to produce biochar by pyrolysis for biotechnological use...
Acetonitrile as adjuvant to tune polyethylene glycol + K3PO4 aqueous two-phase ...
de França do Rosário, Regina Luana Santos; Souza, Ranyere L.; Farias, Fabiane Oliveira; Mafra, Marcos R.; Soares, Cleide M.F.; Passos, HelenaAqueous two-phase systems (ATPS) have been proposed as platforms for the purification of biomolecules, and the application of adjuvants to tune the properties of ATPS phases and their ability to extract and separate biological products investigated. This work addresses, for the first time, the use of acetonitrile (ACN) as adjuvant in ATPS composed of polyethylene glycol (PEG) of different molecular weights (fro...
