“…Biosorption may be simply defined as the uptake or accumulation of chemicals and particulates from the solution by microbial materials (Tsezos and Bell, 1989). The mechanisms responsible for this accumulation are complex and involves adsorption or absorption into various components of the microbial cell.…”

Abstract:The role of fungi in the treatment of wastewater has been extensively researched. Many genera of fungi have been employed for the dye decolourization either in living or dead form. In this study, the removal of an acidic dye, Indigo Carmine (IC), from an aqueous solution by biosorption on dead fungus, Pleurotus ostreatus, was investigated. The effects of contact time, initial dye concentration, amount of dead biomass, agitation rate and initial pH on dye removal have been determined. Experimental results show that an increase in the amount of dead biomass positively affected the dye removal. The highest removal was obtained at 150-200 rpm. Slightly lower removing activities were found at lower agitation rates. The dye adsorption effi ciency was not affected by pH except minor variation in the pH of 2-8. Color removal was observed to occur rapidly within 60 minutes. The removal of dye by dead biomass of P. ostreatus was clearly dependent on the initial dye concentration of the solution. Dye removal was reduced from 93% to 64% as concentration was increased from 50 to 500 mg/L Indigo Carmine. This study showed that it was possible to remove textile dyes by dead biomass of P. ostreatus.

Aerobic transformation by microbial organisms is a dissipation process of pesticides in surface water, but the corresponding information is much less available as compared with their microbial degradation in soil. Bacteria freely floating in water or associated with suspended particles are the key microorganisms degrading pesticides; their species and populations, however, depend on sites and seasons. The various factors related to pesticide properties, experimental conditions and characteristics of surface water are involved in the complex control of microbial processes. Bottom sediment and macrophytes with associated biofilms not only act as sink for pesticides but also provide the habitat for both bacteria and fungi that degrade pesticides. More understanding of each factor is necessary to utilize laboratory biodegradation data for the refined assessment of pesticide behavior in surface water.
