“…Several studies have indicated that more than 30-40% of heavy metals can be removed from a solution with copper concentration greater than 300 mg/L (Andreazza et al, 2011). These results indicate that biomineralization of heavy metals into calcite occurs as a competitive co-precipitation reaction in which suitable divalent cations are incorporated into the calcite lattice.…”

Abandoned mine sites are frequently polluted with high concentrations of heavy metals. In this study, 25 calcite-forming bacteria were newly isolated from the soil of an abandoned metal mine in Korea. Based on their urease activity, calcite production, and resistance to copper toxicity, four isolates were selected and further identified by 16S rRNA gene sequencing. Among the isolates, Sporosarcina soli B-22 was selected for subsequent copper biosequestration studies, using the sand impermeability test by production of calcite and extracellular polymeric substance. High removal rates (61.8%) of copper were obtained when the sand samples were analyzed using an inductively coupled plasma-optical emission spectrometer following 72 h of incubation. Scanning electron microscopy showed that the copper carbonate precipitates had a diameter of approximately 5-10 m m m m mm. X-ray diffraction further confirmed the presence of copper carbonate and calcium carbonate crystals.

“…Biosorption is an important bioremediation process for copper removal and other heavy metals from the environments (Andreazza et al 2011). The capability of strain C1, C2, C4 to grow and to accumulate copper in the presence of high concentration of copper would be helpful in the waste water treatment where microorganisms are directly involved in biological processes for waste water treatment, because the inhibitory effect of heavy metals is a common phenomenon that occurs in the biological treatment of waste water and sewage (Filali et al 2000).…”

Abstract. Irawati W, Parhusip Ajn, Christian S, Yuwono T. 2017. The potential capability of bacteria and yeast strains isolated from Rungkut Industrial Sewage in Indonesia as a bioaccumulators and biosorbents of copper. . Heavy metal pollution is a serious problem as a result of industrialization due to the high production of wastewaters containing high concentrations of heavy metals. Wastewater contains microbial populations adapted to the toxic concentrations of heavy metals and becomes resistant by accumulating copper inside the cells. The aims of the study were to isolate yeast and bacteria from Rungkut Industrial sewage in Indonesia, and to examine the capability of these isolates to accumulate and biosorb copper. The copper resistance was determined by measuring minimum inhibitory concentration (MIC). The capability of isolates to accumulate and biosorb copper were determined by atomic absorption spectrophotometer. Biosorption is described as how much copper is removed from a growth medium with reference to the initial concentration. Of this study, nine bacterial strains and eight yeast strains were obtained with the MICs of 6-7 mM, and 16-20 mM CuSO 4 , respectively. Afterward, we have successfully selected three bacteria and one yeast strains showing the highest copper resistance. The three bacterial strains, designated as C1, C2, and C4 were able to accumulate copper up to 29.93, 508.01, 371.42 mg/cell dry weight, respectively. While the yeast strain, ES9.3 was able to accumulate 0.52 mg/cell dry weight and reduce up to 82.32% copper concentration in the medium. The findings of this study indicated that yeast and bacterial strains were promising microorganisms for removal of copper.

“…The effects of copper on bacteria have been studied extensively, primarily from an environmental contamination perspective (Jonas 1989;Díaz-Raviña and Bååth 1996;Nwuche and Ugoji 2008), a bioremediation perspective (Markwiese et al 1998;Markwiese and Colberg 2000;Andreazza et al 2011), or related to human health and surface disinfection (Lin et al 2002;Santo et al 2011). Use of copper to control bacterial plant pathogens has also been extensively studied (Lukens 1977;Menkissoglu and Lindow 1991).…”

Tests were conducted to determine the concentrations of copper sulfate needed to kill Flavobacterium psychrophilum, the cause of bacterial coldwater disease, either in vitro or on Rainbow Trout Oncorhynchus mykiss eggs. For the in vitro test, a plastic strip dipped in a solution of F. psychrophilum was exposed for 15 min to copper sulfate solutions of 0, 1, 5, 10, 20, 35, 50, 75, or 100 mg/L. Bacteria were "too numerous to count" at concentrations ≤10 mg/L CuSO4; significant reductions in prevalence relative to untreated controls were noted for concentrations ≥35 mg/L. However, CFUs were still observed at 50 and 75 mg/L (20% of plates with tryptone yeast extract salts media). No yellow-pigmented CFUs typical of F. psychrophilum were observed at 100 mg/L CuSO4. For the in vivo test, eggs were exposed for 15 min to 100, 300, 500, and 700 mg/L CuSO4 or 100 mg/L iodine (control). Survival to hatch was significantly lower at 500 (44.3 ± 15.2%, mean ± SD) or 700 mg/L CuSO4 (1.7 ± 0.8%) than for controls treated with 100 mg/L iodine (93.6 ± 0.9%) or at copper sulfate concentrations ≤300 mg/L. The 15-min LD50 and LD10 for copper sulfate were 461 mg/L (95% confidence interval: 457-466 mg/L) and 259 mg/L (251-266 mg/L). The prevalence of yellow CFUs at 100 mg/L CuSO4 (40.0%) was significantly higher than in untreated controls. Significant reductions in yellow CFUs were achieved using 300, 500, or 700 mg/L CuSO4 (7.5, 2.5, or 0.0% of plates with CFUs, respectively) or 100 mg/L iodine (2.5%), relative to untreated control eggs. Overall, since the concentrations of copper sulfate required to eliminate F. psychrophilum were toxic to the eggs, copper sulfate is not recommended for coldwater disease control in Rainbow Trout eggs based on conditions and parameters in this study.
