Quitosana
Tirosinase
Abstract in Portuguese
O presente trabalho apresenta o estudo de processos biotecnológicos para a remoção de fenol de soluções aquosas em regime de batelada em 3 processos distintos (A), (B) e (C) respectivamente. Sendo eles a adsorção de fenóis de soluções aquosas em Quitosana, degradação enzimática de fenóis através da tirosinase em meio aquoso e adsorção/degradação de fenóis de soluções aquosas em Quitosana contendo tirosinase imobilizada. Para isto foram estudadas as influências das variáveis temperatura, pH, concentração da Quitosana e velocidade de agitação no processo (A), temperatura, pH, concentração da tirosinase livre e velocidade de agitação no processo (B) e no processo (C), temperatura, pH, concentração da Quitosana, concentração da tirosinase imobilizada e velocidade de agitação.

Abstract in English
This paper presents the study of biotechnology processes for the removal of pHenol from aqueous solution in batch reactor in 3 separate cases (A), (B) and (C) respectively. As they adsorption of pHenols from aqueous solutions on chitosan, enzymatic degradation of pHenols by tyrosinase in aqueous solution and adsorption / degradation of pHenols in aqueous solutions containing chitosan immobilized tyrosinase. For this we examined the influence of varying temperature, pH, concentration of chitosan and stirring speed of the process (A), temperature, pH, concentration of free tyrosinase and stirring speed of the process (B) and Case (C), temperature , pH, concentration of chitosan, concentration of tyrosinase immobilized and speed of agitation.
