We used conventional methods to investigate the mechanism by which Acidithiobacillus ferrooxidans colonizes a solid surface by assessing pili-mediated sliding, twitching motility, and adherence. A. ferrooxidans slided to form circular oxidized zones around each colony. This suggested that slide motility occurs through pili or flagella, though A.(More)
The genetic variability among 32 Chinese Acidithiobacillus spp. environmental isolates and four reference strains representing three recognized species of the genus Acidithiobacillus was characterized by using a combination of molecular methods, namely restriction fragment length polymorphisms of PCR-amplified 16S rRNA genes and 16S-23S rRNA gene intergenic(More)
The complete sequences of 32 intergenic spacer regions (ISR) from Acidithiobacillus strains, including 29 field strains isolated from coal, copper, molybdenum mine wastes or sediment of different geoclimatic regions in China, reference strain ATCC19859 and the type strains of the two species were determined. These data, together with other sequences(More)
