“…They found that the lead adsorption increased from about 70 to 84 mg g À1 when the used flow rate was decreased from 5 to 3.5 mL min À1 . This finding has been also pointed out by Kumar et al (2011) when evaluating in a continuous packed bed column the efficiency of an immobilized powdered biomass named Trichoderma viride on removing different heavy metals.…”

“…For many years, biosorption has been considered as a promising biotechnology for pollutant removal; several previous studies have shown that non-living microorganisms such as dead bacteria, fungi, blue-green algae, and brown algae are effective for the removal of heavy metals (Holan and Volesky, 1993;Arica et al, 2003;Chojnacka et al, 2005;Kiran and Kaushik, 2008;Kumar et al, 2009;Sharma et al, 2011). Other cost effective biosorbents using immobilized biomass in a granular or polymeric matrix have also been used to remove heavy metals from solution (Kumar et al, 2011;Seo et al, 2013). Alginate has been generally used as the biosorbent material; it contains dead biomass that removes heavy metals from aqueous solutions for the following reasons: (1) high sorption capacity, (2) high mechanical strength in its reacted solid form (i.e., calcium alginate), (3) high chemical stability for recycling, and (4) hydrophilicity (Bhat and Aminabhavi, 2006;Lagoa and Rodrigues, 2009;An et al, 2013).…”

Biosorption experiments were performed to investigate the ability of Ca-alginate beads as biosorbent for the removal of Cu and Cd in acid mine drainage (AMD). From the results of batch experiments, the removal efficiencies of both Cu and Cd for Ca-alginate beads were found to increase to 95% within 3 hours in the temperature range of 15-40 °C, indicating that it is possible to treat AMD using Ca-alginate beads within a short time period under various field conditions. For the column experiments, 381.8 g of Ca-alginate beads was packed in a Pyrex column (2.5 cm in diameter and 100 cm in height) and 119.7 liters (900 pore volumes) of AMD from the Ilgwang mine in Korea was successfully treated. The Cu and Cd removal efficiencies were maintained at levels higher than the Korean remediation goal (86% for Cu and 58% for Cd) and it was possible to treat more than 300 mL of AMD using only 1 g of Ca-alginate beads. Although AMD with a pH below 3 was injected into the column, the pH of the effluents was maintained above 3 for 1,140 pore volumes of flushing due to the buffer action of the beads. In SEM/EDS analysis of the Ca-alginate beads after the experiment, void spaces of the beads were found to be filled with precipitates of heavy metals, showing that Ca-alginate beads can be successfully used as a biosorbent for the removal of Cu and Cd in AMD.

“…In this experiment the initial pH of the culture media was 6.0±0.1 and the pH was not controlled during the experiments. In the case of biosorption by the immobilized to Ca-alginate T. viride biomass the optimum pH was 2.5 [34]. The determined optimal pH was the basis for further research, where the relation between the chromium(VI) ions concentration and the initial concentration of chromium(VI) was determined.…”

Abstract:The purpose of the study was to optimize the removal of Cr(VI) by means of the Trichoderma viride strain isolated from chromium mud samples a well as the Aspergillus niger and Penicillium citrinum strains from other environments. The growth of organism and removal of chromium(VI) was carried out in water solution of various chromium(VI) contents. The research was carried out at optimal pH for each fungus i.e. Aspergillus niger 4.0, Penicillium citrinum 5.0 and Trichoderma viride 4.5. During 14 days of incubation, samples of 5 ml each were collected every day in order to determine chromium(VI) content in the solution and the effi ciency of bioaccumulation of this element was then specifi ed. Furthermore, chromium contents in fi ltrate and mycelium were checked to verify this type of biological activity of microorganisms. The fungi culture investigated in this study could grow at 10-125 mg/l chromium concentration which indicated that it was characterized by high tolerance to various concentrations of chromium. At 125 mg/l chromium, these organisms could accumulate successfully about 90% of chromium. High tolerance of this culture can make it a potential candidate to be a heavy metal scavenger of chromium.
