| reclassification of some species of thiobacillus to the newly designated genera acidithiobacillus gen. nov., halothiobacillus gen. nov. and thermithiobacillus gen. nov. | the species of the genus 'thiobacillus' fall into the alpha-, beta- and gamma-subclasses of the proteobacteria, the type species thiobacillus thioparus being located in the beta-subclass. 'thiobacillus' species exhibit almost as much diversity in dna composition and physiology as is found collectively in all other proteobacterial groups. on the basis of physiological characters and 16s rrna gene sequence comparisons, eight of the existing thiobacillus species are proposed for reassignment to thr ... | 2000 | 10758854 |
| Phylogenetic assessment of culture collection strains of Thiobacillus thioparus, and definitive 16S rRNA gene sequences for T. thioparus, T. denitrificans, and Halothiobacillus neapolitanus. | The 16S rRNA gene sequences of 12 strains of Thiobacillus thioparus held by different culture collections have been compared. A definitive sequence for the reference type strain (Starkey; ATCC 8158(T)) was obtained. The sequences for four examples of the Starkey type strain were essentially identical, confirming their sustained identity after passage through different laboratories. One strain (NCIMB 8454) was reassigned as a strain of Halothiobacillus neapolitanus, and a second (NCIMB 8349) was ... | 2011 | 21858648 |
