Abstract

Effect of High Pressure Homogenization on the Activity and Stability of Protease from Bacillus Licheniformis LBA 46 in Different pH Values

Highlights

  • Pressure is a thermodynamical parameter that has gained importance in a range of fields related to biochemistry and biology [1]

  • Some of the effects of High Pressure Homogenization (HPH) are mainly attributed to cavitation; shear pressure; and turbulence forces, but, the modification of protein structures using

  • Based on the importance of such enzymes, the aim of this study was to evaluate the behavior of a novel alkaline semi-purified protease from B. licheniformis under the treatment of HPH at different pH values

Summary

Introduction

Pressure is a thermodynamical parameter that has gained importance in a range of fields related to biochemistry and biology [1]. Various studies have been performed to change macromolecules structures, such as proteins, and have explored the use of high pressure, in different aspects, in the field of enzymatic technology [2,3,4]. HPH can lead to alterations in the protein structure, stability, and/or enzymatic activity [4,8]. HPH is caused by treatment time, impact (change in flow direction), friction, and heat, which occur simultaneously during the application of the treatment. These forces have the ability to alter configuration and function of proteins [9]
