Article Synopsis
- The study examines the activity of a recombinant chitinase enzyme from leaf-cutting ants, which was effective against both colloidal and solid chitin substrates.
- The analysis revealed that the enzyme produced N-acetylglucosamine as a product and reduced the viscosity of chitin solutions, indicating partial hydrolysis but not complete degradation of chitin.
- The enzyme exhibited greater effectiveness on α-chitin compared to β-chitin and significantly inhibited the growth of a harmful fungus, suggesting potential applications in producing chitin derivatives and as an antifungal agent.
We systematically investigated the effect of β-chitin (BCH) particle size on the preparation of nanocrystals/nanowhiskers (CWH) by acid hydrolysis. Regardless this variable, CWH aqueous suspension exhibited outstanding stability and the average degree of acetylation remained nearly constant after the acid treatment. In contrast, the morphology, dimensions, crystallinity, and molecular weight of CHW were significantly affect by the particle size.
