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 کاملPeriplasmic Proteins of the Extremophile Acidithiobacillus ferrooxidans
Acidithiobacillus ferrooxidans is a chemolithoautotrophic acidophile capable of obtaining energy by oxidizing ferrous iron or sulfur compounds such as metal sulfides. Some of the proteins involved in these oxidations have been described as forming part of the periplasm of this extremophile. The detailed study of the periplasmic components constitutes an important area to understand the physiolo...

This authentication model is applied in distance education where courses are developed in learning management systems. It introduces the features of distance education as well as the biometric sensor operation. It describes the c...
متن کاملPhylogenetic heterogeneity of the species Acidithiobacillus ferrooxidans.
Polyphasic genotypic analysis of 25 Acidithiobacillus ferrooxidans strains isolated from ores and ore concentrates collected in different regions of the world showed considerable strain heterogeneity. Restriction patterns of the chromosomal DNA of these strains obtained by PFGE were specific for each strain. According to the degree of DNA relatedness, 17 of the 23 strains studied were divided i...
