Biosorption of Synthetic Dye by Macrofungi

Abstract

This research project aimed to provide an environmentally friendly method for the decolorization and biosorption of synthetic dye by utilizing fungi as biosorbents. The study was carried out by first growing the fungi in solid medium and then using the fungi as biosorbent to absorb dye in aqueous solution. In the first stage, screening experiments were carried out among 5 different types of fungi, and Pleurotus ostreatus was determined to have the highest growth rate. The Pleurotus ostreatus was recultivated with Remazol Brilliant Blue R dye to determine its dye removal ability. Pleurotus ostreatus sp. exhibited vigorous dye decolorization in agar medium within 2 days. By carrying out batch analysis, 4 parameters were examined, which were the effect of pH, surfactant concentration (Tween 80), salinity concentration and dosage of biosorbent. The results showed that the maximum dye decolourization by Pleurotus ostreatus can be achieved through establishing an acidic condition of pH 2, addition of 0.1mL of Tween 80, 0mg/l of sodium chloride concentration, and dosage of 8 plugs. Lastly, the experimental data was found to fit the Jovanovic Isotherm the most. In conclusion, Pleurotus ostreatus is capable of decolourizing and adsorbing dye particles in the dye aqueous solution.

Isolation, Screening, Characterization, and Optimization of Biosurfactant-Producing Bacteria for Removal of Micropollutants from Textile Effluents

“…Since biosorption is passive metal-ion uptake, it is independent of energy requirement. 12 The biological methods of textile wastewater treatment are effective ways of degrading complex dyes of industry and preferred due to capability for improving the overall quality of wastewater (BOD, COD, TKN, MLSS MLVSS, pH, TDS, and suspended solids). 13 Tang and coworkers 14 reported the degradation of dyes by a variety of bacteria with varied efficacy.…”

Feasibility study of common effluent treatment plant for management of industrial wastewater: Case study of Bangladeshi textile industries

“…Recent advances in wastewater treatment (Tang et al., 2022) could be solution to these issues through the effluent treatment using engineered nanocomposites (Rayhan et al., 2022), carbon nanotubes (Chung et al., 2022), and biosorbents (Lee et al., 2022), among others. However, there is a high cost associated with the establishment of treatment plants.…”
