Bacterial chitinases are integral in breaking down chitin,
the
natural polymer in crustacean and insect exoskeletons. Their increasing
utilization across various sectors such as agriculture, waste management,
biotechnology, food processing, and pharmaceutical industries highlights
their significance as biocatalysts. The current review investigates
various scientific strategies to maximize the efficiency and production
of bacterial chitinases for industrial use. Our goal is to optimize
the heterologous production process using physical, molecular, and
computational tools. Physical methods focus on isolating, purifying,
and characterizing chitinases from various sources to ensure optimal
conditions for maximum enzyme activity. Molecular techniques involve
gene cloning, site-directed mutation, and CRISPR-Cas9 gene editing
as an approach for creating chitinases with improved catalytic activity,
substrate specificity, and stability. Computational approaches use
molecular modeling, docking, and simulation techniques to accurately
predict enzyme–substrate interactions and enhance chitinase
variants’ design. Integrating multidisciplinary strategies
enables the development of highly efficient chitinases tailored for
specific industrial applications. This review summarizes current knowledge
and advances in chitinase engineering to serve as an indispensable
guideline for researchers and industrialists seeking to optimize chitinase
production for various uses.
