Phospholipids (PLs) are the important components of cell membrane of all living organisms. The PL or the cell membrane of the bacteria are the least studied subject as it involves large quantities of material and few methods to assay. The novel study was designed to understand if the cell membrane remains same or it changes during different conditions. The bacteria, Acidithiobacillus ferrooxida...

Using phylogenomic and gene compositional analyses, five highly conserved gene families have been detected in the core genome of the phylogenetically coherent genus Acidithiobacillus of the class Acidithiobacillia. These core gene families are absent in the closest extant genus Thermithiobacillus tepidarius that subtends the Acidithiobacillus genus and roots the deepest in this class. The predi...

In this study, cadmium (Cd)-contaminated soils were bioremediated using the mixotrophic acidophiles in different scale-up cultivation stages. The free and attached bacterial fungal diversities community structures, their effects on soil Cd removal investigated. Percentages of dominant bacteria (Acidithiobacillus, Sulfobacillus, Pseudomonas) fungi (Acidomyces Coniochaeta) between communities exh...

Experiments were carried out to examine redox transformations of copper and chromium by acidophilic bacteria (Acidithiobacillus, Leptospirillum, and Acidiphilium), and also of iron (III) reduction by Acidithiobacillus spp. under aerobic conditions. Reduction of iron (III) was found with all five species of Acidithiobacillus tested, grown aerobically on elemental sulfur. Cultures maintained at p...

the effects of different factors on growth and bio-oxidation efficiency of a native strain of acidithiobacillus ferrooxidans have been evaluated by the utilization of response surface methodology, rsm. medium ph and iron concentration were found to be the most significant factors while temperature and ammonia concentrations had the least weight within the ranges investigated. optimum operationa...

The draft genome of Acidithiobacillus thiooxidans A01 contains 3,820,158 bp, with a G+C content of 53.08% and 3,660 predicted coding sequences (CDSs). The bacterium contains a series of specific genes involved in the oxidation of elemental sulfur and reduced inorganic sulfur compounds (RISCs).

this study deals with bioleaching of the low grade uranium ore of saghand mine in iran using a mixed culture of mesophilic bacteria (acidithiobacillus ferrooxidans, acidithiobacillus thiooxidans and leptospirillum ferrooxidans). experiments were carried out in shaking flask examining the effect of temperature, initial ferrous ion concentration, pulp density and particle size. variations of ph, ...
