Area of Science:

  • Biochemistry and Enzymology
  • Polymer Science
  • Biotechnology

Background:

  • Chitin deacetylases are enzymes found in fungi and insects.
  • These enzymes catalyze the hydrolysis of chitin, converting it into chitosan.
  • Chitosan is a valuable biopolymer with applications in biomedicine, food, cosmetics, and pharmaceuticals.

Purpose of the Study:

  • To explore the use of chitin deacetylases for chitin to chitosan conversion.
  • To present an alternative to the conventional thermochemical production of chitosan.
  • To investigate the potential for producing novel, well-defined chitosan oligomers and polymers.

Main Methods:

  • Enzymatic hydrolysis of chitin using chitin deacetylases.
  • Characterization of the resulting chitosan products.
