title: Copper biosorption by Auricularia polytricha.
abstract: OBJECTIVE
  The objective of the present study was to determine the optimum conditions for copper (Cu) biosorption by Auricularia polytricha mycelium in view of its immobilization in polyvinyl alcohol (PVA).
  
  
  RESULTS
  The adsorption of Cu(II) onto A. polytricha was studied in batch with respect to initial pH, temperature, adsorption time, initial metal ion and biomass concentration. At optimal adsorption conditions, biomass was immobilized in PVA in column and a biosorption capacity of about 90% was obtained.
  
  
  CONCLUSIONS
  Auricularia polytricha strain could successfully be used as Cu biosorbent.
  
  
  CONCLUSIONS
  The low cost and simplicity of the technique make it suitable for the detoxification of contaminated effluents before their environmental discharge.
