Abstract

The reuse of industrial wastewater for agricultural irrigation is often viewed as a positive means of recycling water
due to the advantage of being a constant, reliable water source and availability in large volumes. In the present study,
a laccase enzyme from the fungus Cladosporium oxysporum was used for treatment of textile industry wastewater.
The fungal biomass was subjected to autoclaving (pretreatment) and, three different modes, agitated, aerated and
rotating biological contactor were employed. In all three modes, autoclaved biomass of C.oxysporum was found to
be most effective in removal of dyes from aqueous solutions. Among the three modes of batch studies, agitated
mode was found to be more efficient and easy to operate. The resultant treated effluent from agitated mode as well
as raw effluent was subjected to seed germination bioassays on Vigna radiata seeds. Root length, shoot length, root
biomass and shoot biomass were increased in treated effluent when compared to untreated effluent. Seedlings
irrigated with diluted (20%) untreated effluent yielded a total biomass of 538 mg, whereas treated effluent with 20%
dilution yielded a total biomass of 626 mg. The untreated and treated effluents showed a phytotoxicity of 78.33 and
61.67% respectively and diluted effluents respectively had 26.67 and 20%. These results revealed that treatment of
dye industry effluent with autoclaved biomass at optimum conditions reduced the toxicity of the effluent and the
effluent after proper dilution can be used for irrigation.
