Resumo: A functional model based on Langmuirian adsorption as a limiting mechanism was proposed to explain the effect of cellulase during the enzymatic pretreatment of bran, conducted prior to extraction of proteins, by wet alkaline process from wheat and buckwheat bran materials. The proposed model provides a good fit (r = 0.99) for the data generated thru predictive model taken from the response surface methodology, permitting calculation of a affinity constant (b) and capacity constant (k), for wheat bran (b = 0.255 g/IU and k = 17.42%) and buckwheat bran (b = 0.066g/IUand k = 78.74%).

Modelo funcional baseado na adsorção de Langmuir como mecanismo limitante proposto para explicar o efeito da celulase durante o pré-tratamento enzimático de farelos, visando à extração de proteínas, através do método alcalino-úmido. O referido modelo ajusta se muito bem (r = 0,99) aos dados gerados com base em modelo preditivo obtido da metodologia da superfície de resposta. Pode-se calcular a constante de afinidade (b) e a constante de capacidade (k) para o farelo de trigo e farelo de trigo mourisco (sarraceno), usando uma equação análoga à isoterma de adsorção de Langmuir. Os resultados indicaram que o farelo de trigo mourisco apresenta uma capacidade mais alta para adsorver celulase e, conseqüentemente,'pode-se esperar uma resposta maior ao pré-tratamento com esta enzima.  UEL1980-02-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/581610.5433/1679-0359.1980v2n6p93Semina: Ciências Agrárias; Vol. 2 No. 6 (1980); 93-95Semina: Ciências Agrárias; v. 2 n. 6 (1980); 93-951679-03591676-546Xreponame:Semina.
