Efficient Extraction and Optimization of Amylase and Protease from Bacillus Species: A Comprehensive Study

This review paper provides a comprehensive analysis of the crucial role of Bacillus species in the production of amylase and protease enzymes. Bacillus is one of the most important bacterial sources of enzymes, known for producing high yields of neutral and alkaline amylases and proteases. By breaking down complex starches and proteins into simpler, functional components, these enzymes play a critical role in enhancing efficiency and product quality across various industries, including food processing and textiles. These enzymes exhibit remarkable stability even under extreme conditions, such as high temperatures, fluctuating pH levels, and exposure to organic solvents, detergents, and oxidizing agents. Some Bacillus strains are highly efficient at secreting large quantities of extracellular enzymes, making them essential for industrial enzyme production. The primary objective of this review is to examine the processes involved in the production, purification, and characterization of amylases and proteases from Bacillus species, with a particular focus on those found in the rhizosphere. The first section of the paper discusses the properties and functions of these exoenzymes and highlights key factors that influence their optimization. The second section explores the use of cost-effective substrates for fermentation, aiming to enhance enzyme activity and stability. Given the extensive applications of amylases and proteases in various sectors, significant research has been dedicated to improving their production and efficiency. This review aims to advance our understanding of microbial enzyme systems and support the development of enhanced enzyme production strategies for emerging biotechnological applications.
