Abstract
- Hydrolysis of natural chitin and chitosans was performed in the electron beam plasma (EBP) of oxygen, by means of specially designed electron beam plasmachemical reactor (EBPR). Low molecular water-soluble chitin oligosaccharides with weight-average molecular mass 800–2000 Da and polydispersion index 1.5–2.5 were produced due to action of active oxygen species formed in the EBP. By optimizing the treatment conditions the 95% yield of chitin oligosaccharides was obtained after 2 min whereas the conventional chemical hydrolysis usually takes several days. The studies of the antimicrobial activity of low molecular products formed due to EBP-stimulated degradation showed that they inhibit the multiplication of various mycelial and yeast-like fungi. The technique involved is likely to be promising for the production of bioactive low molecular chitin oligosaccharides and the EBP-stimulated hydrolysis appears to be competitive with technologies conventionally used in the industry.
