“…With this regard, several studies have demonstrated the effect of pH and ionic strength on the adsorption capacity of several types of adsorbents [43,44]. Normally, the maximum adsorption capacity occurs close to the isoelectric point (pI) of biomolecules [45][46][47].…”

“…With this regard, several studies have demonstrated the effect of pH and ionic strength on the adsorption capacity of several types of adsorbents [43,44]. Normally, the maximum adsorption capacity occurs close to the isoelectric point (pI) of biomolecules [45][46][47].The physical adsorption of proteins can be enhanced if the pore diameter of the mesoporous support is close to the size of the protein [31]. Not only the pore diameter, but also the ordering of the pores may interfere with the adsorption capacity of biomolecules.…”

“…Assim, como o pH, a temperatura óptima não sofre deslocamento com a adição de líquidos iônicos no processo de imobilização, para ambos os biocatalisadores imobilizados (BI-SLI e BI-LI4), a temperatura óptima para atingir a maior atividade foi de 37 °C. No entanto, foi observado que BI-LI4 foi ligeiramente mais resistente ao calor, na maioria das temperaturas estudadas, o que pode ser atribuído à ligação de hidrogênio e a interação eletrostática entre líquido iônico e enzima que gerou uma elevada barreira cinética para o desdobramento da enzima, deste modo, a estrutura rígida da enzima foi protegida de ser destruída (Zou et al, 2010). Figura 2 -Efeito do pH e temperatura na atividade relativa dos biocatalisadores imobilizados sem (BI-SLI) e com adição de liquido iônico (BI-LI4).…”
