Solodovnik T. Ecologically safe chitincontaining substances manufacturing from mycelium waste received during biotechnological production of citric acid

The dissertation is devoted to the competitive and ecologically safe method to receive chitincontaining complexes from waste received during biotechnological production of citric acid and research of their physical and chemical properties. The waste is bioweights of fungus Aspergillus niger. The influence of alkaline processing the mycelium waste on a chitincontaining complexes quantitative outcome and their morphological structure is investigated. The offered way allows to receive complexes with stable properties while using various kindes of waste. Sorption, physical and chemical properties of complexes received by different methods were analyzed by a comparative method. The new data for copper, zinc, chromium, cadmium and lead ions sorption from water solution on chitin- and chitosancontaining complexes are received. It is established, that chitincontaining complexes are strong at pH = 5 and are capable for effective heavy metals ions absorption from acid water solutions. The opportunity of chitincontaining complexes use for petroleum and dyes sorption is shown.
