    • Preparação e caracterização de derivados de enzimas industriais em quitosana 

      Adriano, Wellington Sabino (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Engenharia Química - PPGEQ, , 25/04/2008)
      In this work, several strategies were tested to improve the covalent multipoint attachment of chymotrypsin, carboxypeptidase A and cellulase on chitosan. Hybrid gels with different internal structures were obtained using ...

    • Hidrólise controlada de proteínas do soro de queijo usando carboxipeptidase A e alcalase® imobilizadas multipontualmente em agarose. 

      Tardioli, Paulo Waldir (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Engenharia Química - PPGEQ, , 22/08/2003)
      High value food protein hydrolysates can be obtained by sequential hydrolysis of proteins with trypsin, chymotrypsin, carboxypeptidase A (CPA) and Alcalase® (commercial preparation of subtilisin). For the process to be ...

    • Estudo da imobilização de celulase em géis de quitosana. 

      Martins, Rafael Elias (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Engenharia Química - PPGEQ, , 29/01/2007)
      Cellulases are enzymes that catalyze the hydrolysis of cellulose producing glucose. Immobilization and stabilization of these enzymes could improve enzymatic process making it more attractive by reducing costs during their ...
