“…The adsorption peak around 1638 cm -1 shifts to 1626 cm -1 after biosorption. This suggests that the free carboxyl groups have changed into carboxylate, a phenomenon which normally occurs during the reaction between cadmium and carboxyl [19]. Such interaction is consistent with the good fitting of biosorption data with Langmuir isotherm since presence of carboxyl directly implies site specific interactions (an archetypal notion assumed in the Langmuir equation).…”

The mycelial growth kinetics, cadmium biosorption capacity and main governing biosorption mechanism of Pleurotus ostreatus (oyster mushroom) have been determined in this study. The fungus mycelium exhibits a sigmoidal (S-shaped) growth curve in which the growth rates for the lag and exponential phases are 0.1 and 0.31 g/L.day, respectively. The grown fungus is subjected to elemental, infra-red and scanning electron microscopy-energy dispersive x-ray spectroscopy analyses while biosorption data are fitted to established adsorption isotherm models, namely, Langmuir, Freundlich and Dubinin-Radushkevich. It is strongly suggested that the main governing mechanism involved is chemisorption due to good fitting of biosorption data to Langmuir and Dubinin-Radushkevich models with possibility of involvement of both ion exchange and complexation. Data presented in the study are very useful for design of future pilot-or industrial-scale biosorption water purification system.Running title: Biosorption of cadmium using Pleurotus ostreatus

“…Cr(VI) removal was 91.03% using A. niger and 87.95% and 86.61% with A. sydoni and P. janthinellum [162]. Lastly, the brown-rot fungus Lentinus edodes was used as an efficient biosorbent for the removal of Cd from water and three kinds of adsorption models were applied to simulate the biosorption data [163].…”

Abstract:One of the major problems facing the industrialized world today is the contamination of soils, ground water, sediments, surfacewater and air with hazardous and toxic chemicals. The application of microorganisms which degrade or transform hazardous organic contaminants to less toxic compounds has become increasingly popular in recent years. This review, with approximately 300 references covering the period [2005][2006][2007][2008], describes the use of fungi as a method of bioremediation to clean up environmental pollutants.

“…Previous studies reported that fungal isolates have the ability to remove poisonous metal ions from waste, e.g. A. niger 7,8 , Phanerochaete chrysosporium 9 , white-rot fungi 10 , M. racemosus 11,12 , R. arrhizus 13 and the brown-rot fungi L. edodes 14 . Capacity of fungi in biosorption of hazardous metals due to contain of fungi on chitin and lignin, exudation of organic acids by fungi or adsorption of metal ions to fungal cell wall [15][16][17] .…”

The present study describes the potential of mixed fungal isolates, i.e. Aspergillus niger, Penicillium chrysogenum and Rhizopus oryzae for the removal of zinc(II) and copper(II) from aquatic environments. Capacity of mixed fungal biomass to adsorb Zn(II) and Cu(II) were studied in batch sorption experiments as bioremediators. Optimal conditions from contact time, pH, initial metal ion concentration and temperature for remediation of Zn(II) and Cu(II) were studied. Typically, the uptake of Zn(II) and Cu(II) rises with increasing pH up to 4.0. Optimal metal concentration was 150 mg/l when the maximum removal of copper and zinc was 69.5% and 30.3% respectively, was observed at initial metal concentration. Maximum uptake for metals was achieved after 15 min. The maximum biosorption for copper and zinc by selected fungi was achieved at 7.0 g of biosorbent. IR spectrum of three fungal species showed the presence of C=O groups, amine and amide N-H functional stretch.Keywords: Biosorption, copper, electroplating effluent, fungal isolates, zinc.WASTEWATER during electroplating activities involves poisonous heavy metals like chromium, mercury, zinc, nickel, cadmium, phosphorus and copper which build up in the food chain and cause different pathological states 1,2 . In recent years, association of different microbes has been used for wastewater treatment as bioremediators, as it was considered to have greater capability over pure and single isolates. The axenic cultures were devised to be mineralized rapidly and completely by the metabolic activity of different microorganisms 3 . The interactions between different heavy metals and microorganisms might be due to antagonistic, additive effects or synergic. These interactions might be multifaceted and distinguished which depends on the type of heavy metal ion and microbial species consortium. The collective effect of different heavy metals may be toxicity or growth stimulation in the same microbial consortium assorted from the additive effect of the single metal ions 4 . Fungi have diverse mechanisms for bioremediation of heavy metals, including metal uptake by cell-wall components, accumulation inside the cell or extracellular chelation by phytochelatins and metal lothioneins 5 . Waste samples were collected from a polluted water source near Al-Madina electroplating industry, Alipur Chattha, Pakistan, in sterilized and cleaned 1 l glass bottles with stopper. All samples were treated with 372 mg/l EDTA as the chelating agent to reduce toxicity in samples burdened with heavy metals. During examination, the samples were fresh, and were occurred immediately after return to the laboratory.The fungi were isolated by filtration of the electroplating waste for collection of fungal propagules using 0.45 m pore size filter paper 6 . The fungal spore suspension was prepared in 50 ml of saline solution, and 100 l of spore suspension was inoculated in sterilized petri dish with modified culture medium consisting of aureomycin (0.35 mg/l), glucose (10 g/l), rose bengal (0.035 mg/l), Cu...
