Abstract

Our paper investigates the removal efficiency of toxic hexavalent chromium from aqueous solutions by the fungal strain Trichoderma viride, isolated from forest soil and exploited in the form of dead and living biomass. Our findings show that lower pH values ensure maximum removal efficiency (100%) for dead biomass, while nearly neutral pH values are suitable for Cr(VI) removal by the living microorganisms. Data processing by different kinetic models and FTIR analysis is allowed to elucidate the mechanism of Cr(VI) removal by dead T. viride as’adsorption-coupled reduction’, while the intracellular reduction is the dominating mechanism for Cr(VI) removal by living T. viride. An optimization procedure based on SADE-NN-3 alternative of the Differential Evolution (DE) algorithm allowed setting various process parameters and obtaining conditions which ensure 100% removal efficiency.
