“…Nowadays, there is a trend to use the alternative and low-cost materials for arsenic removal from the waters in laboratory or medium-scale experiments. Effectiveness of chemically modified or native biomass in processes of arsenic removal was evaluated and proved by various authors (Abdel-Ghani et al, 2007;Boddu et al, 2008;Cernansky et al, 2007;Loukidou et al, 2003;Malakootian et al, 2009;Murugesan et al, 2006;Rahaman et al, 2008;Seki et al, 2005).…”

ABSTRACT:Arsenic is a ubiquitous element in the environment and occurs naturally in both organic and inorganic forms. Under aerobic condition, the dominant form of arsenic in waters is arsenate, which is highly mobile and toxic. Arsenic poisoning from drinking water remains a serious world health issue. There are various standard methods for arsenic removal from drinking waters (coagulation, sorption, ion-exchange reactions or methods of reverse osmosis) and alternative methods, such as biosorption. Biosorption of arsenic from natural and model waters by native or chemically modified (with urea or ferric oxyhydroxides) plant biomass prepared from sawdust of Picea abies was studied. The kinetic of the adsorption process fitted well the pseudo second order adsorption model and equilibrium was achieved after 2 h. The results showed that biosorption was well described by both Langmuir and Freundlich isotherms. The maximum biosorption capacity of the sawdust modified with ferric oxyhydroxides, evaluated by Langmuir adsorption model, was 9.259 mg/g, while the biosorption capacity of unmodified biosorbent or biosorbent modified with urea was negligible. The adsorption capacity is comparable to results published by other authors, suggesting that the prepared chemically modified biosorbent has potential in remediation of contaminated waters.

“…The most prominent features of biosorption are the use of low cost and highly efficient biomass materials to adsorb heavy metals even present at very low concentrations (Yu et al, 2001). Various types of biomass, including bacteria (Scott and Palmer, 1990;Chang et al, 1997;Selatnia et al, 2004;Iyer et al, 2005), yeast (Huang et al, 1990;Volesky et al, 1993;Seki et al, 2005;Göksungur et al, 2005), fungi (Lewis and Kriff, 1988;Fourest et al, 1994;Dursun et al, 2003;Pal et al, 2006;Tunali et al, 2006), and algae (Xue et al, 1988;Yu et al, 1999;Lodeiro et al, 2005;Hansen et al, 2006;Vijayaraghavan et al, 2005Vijayaraghavan et al, , 2006, have been investigated with the aim of finding more efficient and cost-effective metal-removal biosorbent. Among them, marine algae with large available quantities in many regions are a kind of promising biological resources.…”

Biosorption of Cu 2+ and Pb 2+ by Cladophora fascicularis was investigated as a function of initial pH, initial heavy metal concentrations, temperature and other co-existing ions. Adsorption equilibriums were well described by Langmuir and Freundlich isotherm models. The maximum adsorption capacities were 1.61 mmol/g for Cu 2+ and 0.96 mmol/g for Pb 2+ at 298 K and pH 5.0. The adsorption processes were endothermic and biosorption heats calculated by the Langmuir constant b were 39.0 and 29.6 kJ/mol for Cu 2+ and Pb 2+ , respectively. The biosorption kinetics followed the pseudo-second order model. No significant effect on the uptake of Cu 2+ and Pb 2+ by co-existing cations and anions was observed, except EDTA. Desorption experiments indicated that Na 2 EDTA was an efficient desorbent for the recovery of Cu 2+ and Pb 2+ from biomass. The results showed that Cladophora fascicularis was an effective and economical biosorbent material for the removal and recovery of heavy metal ions from wastewater.

“…Physicochemical method are practiced and biological remediations are also taken into consideration [12][13][14][15]. Compared with physicochemical method, microbial remediation is more cost-effective and rarely introduces secondary pollution [16][17][18][19], especially for metal reduction in bioremediation. A wide variety of microorganisms capable of reducing aqueous hexavalent chromium ions have been reported including Staphylococcus epidermidis L-02 [11], Acinetobacter [20], Arthrobacter [21], Bacillus sp.…”

Background: Lanzhou reach of the Yellow River is contaminated by heavy metals including chromium perennially. The microbial community within the sediment is very active. Yet the study on the bacteria in this distinctive microbial community is still scarce.Results: LZ-01, a Gram-positive hexavalent chromium-reducing bacterium was isolated from the soil sample collected at a petrochemical corporation wastewater discharge site of Lanzhou reach. It was able to aerobically reduce 94.5% of 0.4 mM Cr (VI) to Cr(III) in 120 hours. Cd (II) and NaN 3 treatment both repressed Cr(VI) reduction in LZ-01 and Cr(III) precipitates were detected both on the cell membrane and in the cytoplasm by Transmission Electron Microscopy (TEM) imaging. LZ-01 also demonstrated resistance to 4 mM As (V) and 9 mM U (VI). LZ-01 was closely related to Staphylococcus aureus revealed by 16S rRNA sequence analysis. Comparison of cellular fatty acid components and Vitek phenotype identification provided further evidences that LZ-01 is a novel subspecies of S. aureus. Conclusions:A chromate-reducing bacterium LZ-01 identified as a novel subspecies of S. aureus was isolated from Lanzhou reach of the Yellow River. Cd (II) and NaN 3 treatment and TEM images suggested that Cr(VI) was reduced not only intracellularly but also on the cell membrane. All the results indicate that the isolate has a great potential for bioremediation of Cr (VI)-contaminated environment. Staphylococcus aureus is a facultative Gram-positive coccus-shaped bacterium [27] that is best known for its ability to cause a range of illnesses [27,28]. Several recent studies report that S. aureus is involved in environmental metal remediation [4,29] and S. epidermidis which is closely related to S. aureus is able to anaerobically reduce Cr(VI) to Cr (III) [11]. However, there is no direct evidence that S. aureus can reduce Cr(VI). In this study, we screened the Lanzhou reach river bank soil for Cr(VI) reducers and isolated a novel subspecies of S. aureus strain LZ-01, which reduces Cr(VI) to Cr(III) aerobically. 16S rRNA sequencing and fatty lipids profiling showed that strain LZ-01 is closely related to S. aureus. Comparison of Vitek phenotype identification showed that there were 7 different reactions out of 64 between LZ-01 and type strains of Staphylococcus aureus. LZ-01 reduces Cr(VI) in a highly efficient manner suggesting that it may be useful for Cr(VI) reduction studies in Lanzhou reach. Journal of Bior emediation & Biodegradation Materials and Methods Soil sample collectionThe sampling site was 60 kilometers west of central Lanzhou city and adjacent to the upper reach of the Yellow River. The actual location was close to a petrochemical corporation waste water discharge site. The latitude and longitude of the sampling site is 36°06'N 103°39'E, (Figure 1). The pH of soils at the sampling site ranged from 5.0 to 6.0 with temperature around 18°C at the time of collection. The soil samples were collected from 15 cm below surface horizon and stored in sterile aluminum boxes a...
