| Abstract: |
| Chitin is one of the most abundant organic macromolecules on Earth， which is found in terrestrial and aquatic ecosystems. Chitinases are widely distributed in nature， and have ecologically and biotechnologically important functions. This review introduces the degradation process of chitin， the classification of chitinases， and the distribution of chitinases in Bacteria， Fungi and Archaea. We summarize recent research progress on microbial chitinases and their biotechnological applications in environmental waste management， agricultural and medical industries. Also， we provide future perspectives on the development and contribution of microbial chitinases in emerging marine biotechnology industries， based on the abundant marine resources in Guangdong-Hong Kong-Macao Greater Bay Area. |
