“…These results showed that both Alternaria alternata and Penicillium aurantiogriseum are suitable for using as cadmium and mercury accumulators in wastewater. Similar results with respect to biosorption of cadmium and other heavy metals by fungi and bacteria have been reported earlier (Chang et al, 1997;Puranik and Paknikar, 1999;Costa et al, 2001;Pardo et al, 2003;Kefala et al, 1999;Ghoslan et al, 1999;Say et al, 2001;Watanabe et al, 2003;Ozdemir et al, 2004;Ayangbenro, and Babalola, 2017). Kumar et al, (2014) 2.55 mg/g of Cr respectively.…”

“…This phenomenon was demonstrated in a previous study [34]. The uptake of metals by biomass may be due to one or more of the following processes: ion exchange, physical adsorption, chemical sorption, complexation and microprecipitation [36][37][38]. 24 h after the addition of hydrogen sulfide, a notable decrease in the heavy metals in solution was obtained and this could be due to the generation of insoluble compounds.…”

a b s t r a c tThe precipitation of chromium(III), copper(II), manganese(II) and zinc(II) by biogenic hydrogen sulfide generated by sulfate-reducing bacteria, Desulfovibrio sp., and the degradation of total petroleum hydrocarbons (TPH) in the presence of heavy metal by Pseudomonas aeruginosa AT18 have been carried out. An anaerobic stirred tank reactor was used to generate hydrogen sulfide with Desulfovibrio sp. culture and the precipitation of more than 95% of each metal was achieved in 24 h (metal solutions contained: 60, 49, 50 and 80 mg L −1 of chromium, copper, manganese and zinc sulfates). A stirred tank reactor with P. aeruginosa AT18, in the presence of the heavy metal solution and 2% (v/v) of petroleum, led to the degradation of 60% of the total petroleum hydrocarbons and the removal of Cr(III) 99%, Cu(II) 93%, Zn(II) 46% and Mn(II) 88% in the medium through biosorption phenomena. These results enabled the development of an integrated system in which the two processes were combined. The overall aim of the study was achieved, with 84% of TPH degraded and all of the metals completely removed. Work is currently underway aimed at improving this system (decrease in operation time, culture of P. aeruginosa in anaerobic conditions) in an effort to apply this process in the bioremediation of natural media contaminated with heavy metals and petroleum.

“…At highly acidic pH (<3) lead ions compete with hydrogen ions on the binding sites of microbial cells. However, at higher pH (>5) solubility of lead was lowered (Chang et al, 1997). The variation in external pH can also affect the degree of protonation of potential ligand that contribute to metal binding (Tobin et al, 1984).…”

The bacteria with a high growth rate were isolated from polluted industrial waste water. The bacteria Bacillus anthracis PS2010 have variable resistant to heavy metals such as Cd, Cu, Co, Zn and Pb. Out of which the minimal inhibitory concentrations were 0.6, 2.0, 0.8, 4.0 and 3.0 mM, respectively. The potent bacterium has optimal biosorption capacity raised according to the metal, incubation temperature, pH of the solution and contact time. Under optimal conditions, the bacterium was capable of taking up the heavy metals Cd, Cu, Co, Zn and Pb at 3.41, 2.03, 4.75, 5.22 and 6.44 mg/g dry weight. Transmission electron microscopy showed accumulation of Pb metal external to bacterial cells. The mechanism of heavy metal tolerance in Bacillus anthracis PS2010 is chromosomally encoded. Bacillus anthracis harbored no plasmid.
