An Investigation the Effect of Acidithiobacillus Ferrooxidans Bacteria on Biomachining of Titanium Alloy and Copper
Recent advances in technology have increased the necessity of using components with Micro and Nano dimensions. In recent years, the use of bacteria as a renewable tool has hopeful applications in producing different work-pieces. In this study, the effect of Acidithiobacillus Ferrooxidans (A.F) on Vt20 (Titanium alloy) and Cu were investigated. The results illustrated that in the medium of the A...
متن کاملCytochromes c of Acidithiobacillus ferrooxidans.
The chemolithoautotrophic Gram-negative bacterium Acidithiobacillus ferrooxidans is versatile and can grow on a number of electron donors and acceptors. In the A. ferrooxidans ATCC 23270 genome, computer analysis identified 11 genes encoding putative cytochromes c. At least eight putative cytochromes c were differentiated on gels in ATCC 33020 cells grown on ferrous iron or sulfur. All these cy...
متن کاملCopper Recovery from Chalcopyrite Concentrate by an Indigenous Acidithiobacillus ferrooxidans in an Air-Lift Bioreactor
In this study, effects of solid concentration, temperature, and initial Fe2+ concentration on bioleaching of sulfide mineral (chalcopyrite) obtained from Sarcheshmeh Copper Mine in the region of Kerman located in the south of Iran were investigated. A mesophilic iron oxidizing bacterium, Acidithiobacillus ferrooxidans has been isolated from a typical chalcopyrite copper concentra...
متن کاملOrganoarsenic resistance and bioremoval of Acidithiobacillus ferrooxidans.
The tolerance and bioremoval of dimethylarsinic acid (DMA(V)) by Acidithiobacillus ferrooxidans (A. ferrooxidans) were investigated here. The inhibitory concentration (IC) of DMA(V) was determined for A. ferrooxidans. The effects of various parameters such as pH, contact time, initial DMA(V) concentration, biosorbent dose and temperature were systematically examined to study the biosorption pro...
متن کاملTranscriptional and functional studies of Acidithiobacillus ferrooxidans genes related to survival in the presence of copper.
The acidophilic Acidithiobacillus ferrooxidans can resist exceptionally high copper (Cu) concentrations. This property is important for its use in biomining processes, where Cu and other metal levels range usually between 15 and 100 mM. To learn about the mechanisms that allow A. ferrooxidans cells to survive in this environment, a bioinformatic search of its genome showed the presence of at le...
