Abstract

The fungus, Cladosporium oxysporum Berk. and Curt. was screened for their ability to
decolourize Reactive Blue HER in aqueous solutions and observed that had higher dye decolourization
(99.81 %) achieved by live biomass, dead biomass. In batch mode (Agitated mode), the lower
concentrations (10 mg/L) of Reactive Blue showed complete removal (100%) at an equilibrium time of
60 min for both live and autoclaved biomass. Dye adsorption isotherm, Langmuir model fitted well with
R
2
values more than 0.9. RL (equilibrium parameter) values (indicating type of isotherm) of live and
autoclaved mycelia at different adsorbate concentrations were always less than one and more than
zero thereby indicating favourable adsorption of dyes onto the adsorbent. With the increase of dosage,
no re-stabilization phenomenon or removal reduction was observed. Highest adsorption was observed in
autoclaved biomass, 48.31 mg/g. Agitated mode was found to be more efficient and easy to operate for
the removal of dyes.
