ABSTRACT
Chitinases are a group of enzymes that catalyze chitin hydrolysis and are present in all domains of life. Chitinases belong to different glycosyl hydrolase families with great diversity in their sequences. Microorganisms such as bacteria and fungi produce chitinases for nutrition, and energy, and to parasitize the chitinous hosts. But chitinases from bacteria are of special interest due to their ubiquitous nature and ability to perform under extreme conditions. Chitinases produced by bacteria have been explored for their use in agriculture and industry. In agriculture, their main role is to control chitin-containing insect pests, fungal pathogens, and nematodes. In the seafood industry, they found their role in the management of processing wastes which are mainly chitinous substances. Chitinases are also used to synthesize low molecular weight chitooligomers which are proven bioactive compounds with activities such as anti-tumour, antimicrobial, and immunity modulation. Considering their importance in ecology and biotechnological applications, several bacterial chitinases have been studied in the last two decades. Despite their potential, bacterial chitinases have a few limitations such as low production and lack of secretion systems which make the wild-type enzymes unfit for their applications in industries and other allied sectors. This review is an attempt to collate significant works in bacterial chitinases and their application in various industries and the employment of various tools and techniques for improvement to meet industrial requirements.
