“…Our results found that the sorption capacity increased and reached to the saturation value as the initial Cu +2 concentration increased in aqueous solution suggesting saturation kinetics with respect to Cu +2 concentration. This result was similar with the results of Iram and Abrar (2015) who observed that by using of Aspergillus flavus and Aspergillus niger biomass as biosorbents, Cu +2 uptake was increased by increasing of initial Cu + 2 concentration in aqueous medium. Mukhopadhyay et al (2007) and Sheng et al (2007) illustrated that, at high metal ion concentration, the number of ions adsorbed is more than at low metal concentration, where more binding sites were free for interaction.…”

Background: Biomass produced as a byproduct from the β-mannanase production process by Aspergillus tamarii NRC 3was evaluated as a biosorbent for the removal and recovery of some heavy metal ions.Results: Under optimal conditions, the isolated strain recorded the highest β-mannanase activity (31.88 Uml −1 ). Thus, the biomass produced from mannanase production process as a byproduct was evaluated as a biosorbent for the removal and recovery of some heavy metal ions from aqueous solutions and an industrial wastewater. The fungal biomass was found to be efficient for the removal of Cu +2 and some heavy metal ions. The biosorption process of copper(II) by Aspergillus tamarii NRC 3 biomass was affected by changing of time, temperature, pH, metal ions concentration, the presence of some heavy metals, and biomass concentration. The rate of Cu +2 uptake from Cu +2 solution proceeded rapidly, and it appeared to be virtually complete during the initial 5 min (92%); the maximum uptake of Cu +2 appeared at 30°C, pH 5, and biomass concentration 5 g w/w. On the other hand, the fungal biomass was to remove considerable proportion of Pb 2+ , Co +2 , Ni 2+ , Fe +3 , and Cr 3+ in addition to Cu 2+ . The uptake of Cu +2 by pretreated biomass was studied. Recovery of the sorbed metal ions by desorbing agents and the potential reuse of the regenerated biomass in metal ions uptake (reloading) were evaluated. Conclusions: Aspergillus tamarii NRC 3 biomass seems to be quite feasible in the removal of heavy metal ions especially Cu +2 from aqueous solutions.

“…These anionic cell walls can fix metals, and provide sites for nucleation and growth of minerals. This property has been the basis for many heavy metal removal studies using bacterial biomass [9]. The walls of gram-positive bacteria are efficient metal chelators.…”

“…This implies that the removal mechanism is not metabolically controlled. In contrast, the term bioaccumulation describes an active process whereby removal of metals requires the metabolic activity of a living organism [9,10].…”

Metals and chemicals have been increased in industrial processes which they contain a high level of toxic heavy metals and cause a lot of disadvantages for the environment and human health .Biosorption of Pb (П) ions has been studied from aqueous solutions in a batch system by using a bacterial strain isolated from petrochemical wastewaters. Strain 8-I was selected to study the impact of different factors on removal rate. According to morphological, physiological and biochemical characterizations of the strain and in comparison with other studies the strain was tentatively identified as Bacillus sp strain8-I. The maximum Lead biosorption capacity of 8-I isolate was determined to be 41.58 % at pH 4.0 with 80 mg/l concentration in 48 hours equilibrium time. The comparison between the biosorption capacity of live (45.50 mg/g), heat inactivated (30.23 mg/g) and NaN3 pretreated biomass (26.86 mg/g) were indicated that the ability of live biomass for both of active and passive uptake of lead.

“…After 48 h, the fungal biomass was separated from medium using filtered through Whattman filter paper. The biomass was dried by the process of drying on hot oven in order to absorb the moisture content at temperature of 120°C for about 3-4 days and was utilized in further biosorption studies [26]. …”

Abstract. The heavy metal resistant isolate FR1 was identified using phenotypic and genotypic characteristics; it was classified as Aspergillus terreus strain. Lactose and yeast extract were favorable for Cr +5 and Cu +2 ions biosorption by tested strain after 6 days incubation period. The positive significant variables (yeast extract, temperature & inoculum size or lactose, yeast extract, temperature & incubation period) affecting heavy metals biosorption using Placket-Burman statistical experimental design in presence Cr +5 and Cu +2 were further optimized by using response surface methodology. It was found that the highest growth of strain in presence of Cr +5 and Cu +2 (4.31 and 3.69 gL -1 ) were attained at 0.15% yeast extract, 2% inoculum size & incubated at 28°C and 0.65 % lactose, 0.15% yeast extract, an incubation temperature of 30 °C and 8 days incubation period, respectively. There is no significant difference between absorption and adsorption mechanism for reduction of heavy metals from Egyptian phosphatic fertilizer sample.
