Efficiency of Application of hypomyces rocellus Biomass—the Waste of Die Preparation—in Water Purification for Removal of Heavy Metals

Abstract

In recent years, attempts are made to utilize valuable components of the biomass of microscopic fungi—waste of microbiologic productions. Polysaccharides of a cellular wall of fungi are widely used to obtain various biosorbents, mainly high-molecular ones—chitin or chitin–glucan complex. We developed the method of fabrication of polysaccharide complex from the biomass of the hypomyces rosellus VKP F-242 microscopic fungus—the manufacturing waste of the die, and investigated its certain physicochemical and sorption properties. According to the data of the IR spectrum and elemental analysis, a polysaccharide complex isolated from mycelium is close to chitin of crustaceans and other filamentous fungi. A polysaccharide complex possesses the higher sorption ability than the worked-out fungus biomass. The degree of recovery of metal ions is 89% and 77% for Al3+, 55% and 43% for Cu2+, and 80% and 70% for Co2+, respectively.
