Chitin-chitosan complex from Rhizopus oryzae obtained on a pea culture medium, and some of its physicochemical properties

Abstract

The article provides information about the way of obtaining chitin-chitosan biosorbents from the fungus Rhizopus oryzae, using mild deacetylation and demineralization conditions. Such physicochemical properties as deacetylation degree, total ash, weight loss on drying etc. were determined. Method of obtaining the chitin-chitosan complex, shown in the current study, allows to obtain a pure biosorbent with a high degree of deacetylation possible to be further used as entero-and hemosorbent.
