Indigenous acidophilic bacteria separated from mine-waste can be used in return for the addition of the reagents like sulfuric acid. Among the tailings bacteria, Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans are of the most-studied ones for the bioleaching and bioremediation of elements. In this work, the isolation and characterization of the mentioned bacteria are studied by...

background mercury is one of the most toxic heavy metals. even a small amount of it is toxic for all living organisms. some of bacteria have developed special resistance mechanisms against mercury, in addition to resistant to different antibiotics. these bacteria usually acquire hg and antibiotic resistance genes via horizontal gene transfer in their habitat. objectives the aim of this study wa...

Magentotactic bacteria are the types of bacteria capable of orientation in an external magnetic field because of the ability to produce structures called magnetosomes. Magnetosomes, nanometer-scale structures, are present in most of the magnetotactice bacteria. They are intracellular organelles composed of magnetic iron mineral crystals individually surrounded by a phospholipid layer. Because o...
