Polyhydroxyalkanoates: waste glycerol upgrade into electrospunfibrous scaffolds...
Canadas, Raphaël F.; Cavalheiro, João M.B.T.; Guerreiro, João D.T.; Almeida, M. Catarina M.D. de; Pollet, Eric; Silva, Cláudia Lobato da"This integrated study shows that waste glycerol can be bio-valorized by the fabrication of electrospun scaffolds for stem cells. Human mesenchymal stem cells (hMSC) provide an interesting model of regenerating cells because of their ability to differentiate into osteo-, chrondro-, adipo- and myogenic lineages. Moreover, hMSC have modulatory properties with potential on treatment of immunologic diseases. Electr...
Synthesis of ethyl butyrate in organic media catalized by Candida rugosa lipase...
Pires-Cabral, P.; Fonseca, M.M.R. da; Ferreira-Dias, S.A kinetic study on the synthesis of ethyl butyrate in n-hexane, catalyzed by Candida rugosa lipase immobilized in two hydrophilic polyurethane foams (“HYPOL FHP 2002” and “HYPOL FHP 5000”)was performed. With the “FHP5000” foams, esterification rates and conversion were always higher than those obtained with “FHP2002”. For both immobilized preparations, BA did not cause any inhibition on the enzymatic activity, ...
