Protein composition of the carboxysomes of Thiobacillus neapolitanus
Archives of Microbiology, 1986 For purifying carboxysomes of Thiobacillus neapolitanus an isolation procedure was developed which resulted in carboxysomes free from whole cells, protoplasts and cell fragments. These purified carboxysomes are composed of 8 proteins and at the most of 13 polypeptides.

Thiobacillus cuprinus sp. nov., a Novel Facultatively Organotrophic Metal-Mobilizing Bacterium. [PDF]
, 1990 Five strains of mesophilic, facultatively organotrophic, ore-leaching eubacteria were isolated from solfatara fields in Iceland and a uranium mine in the Federal Republic of Germany. The new organisms are aerobic gram-negative rods. They can use sulfidic

on the Permeability of Thiobacillus Neapolitan Us to Thiosulphate [PDF]
Australian Journal of Biological Sciences, 1965 Freshly prepared cells of T. neapolitanus had an effective thiosulphate-impermeable volume of 2·21 ml/g dry weight; on treatment of the bacteria with n-butanol this value fell to O· 86 ml/g dry weight. T. neapolitanus catalysed an exchange of sulphur between sulphite and the inner-sulphur group of thiosulphate although the bacteria appeared to be ...
