The metal — metal interactions in biological systems. Part I. Escherichlia coli

Zinc and Lead Biosorption by Delftia tsuruhatensis: A Bacterial Strain Resistant to Metals Isolated from Mine Tailings

“…For example, some used an aqueous medium [14,15] or even a solid medium, but adding the metallic solution once the medium had been solidified [16]. Therefore a direct comparison with our results is not appropriate.…”

Single and combined effects of nickel (Ni(II)) and cobalt (Co(II)) ions on activated sludge and on other aerobic microorganisms: A review

“…This is in broad agreement with the study by Barabasz at al. [180], according to which, the growth of E. coli is stimulated by the presence of up to 25 mg(Co(II)) L −1 , while no significant effect was observed by the same amount of Ni(II). According to Falih [178], 100 mg(Co(II)) L −1 were stimulatory to the growth of P. chrysosporium, while the same amount of Ni(II) acted as growth inhibitor.…”

“…However, according to the above researchers [180], simultaneous addition of even small amounts of both nickel and cobalt was absolutely lethal to the growth of the above microorganism.…”

“…Barabasz at al. [180] Escherichia coli Gikas [12] Activated sludge Falih [178] Phanerochaete chrysosporium Pearse and Sherman [163] Saccharomyces cerevisiae Hashem and Bahkali [150] Fusarium solani Schmidt and Schlegel [140] Various bacteria isolated from metal contaminated sites Heukelekian and Gellman [114] Activated sludge Wu et al [204] Escherichia coli Otth et al [142] Arcobacter butzleri Yang and Ehrlich [170] Gram-negative marine rod Frankenberger [207] who studied bacterial isolates from chromium Cr(VI) contaminated sites, reported that cells able to grow at Cr(VI) concentrations up to 500-1000 mg L −1 , were also able to tolerate equally single nickel or cobalt up to a concentration of approximately 50 mg L −1 .…”

“…Barabasz et al [180] who worked with E. coli reported growth stimulation by the addition of 5-25 mg(Co(II)) L −1 , while addition of similar amounts of nickel had no effect on the growth of E. coli. However, according to the above researchers [180], simultaneous addition of even small amounts of both nickel and cobalt was absolutely lethal to the growth of the above microorganism.…”
