Protein composition of the carboxysomes of Thiobacillus neapolitanus
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.

Factors Influencing Degradation of Mercaptans by Thiobacillus thioparus TK-m (1)
Degradation of methylmercaptans by Thiobacillus thioparus TK-m was influenced by pH of the reaction medium. Ratios of headspace concentrations in empty vials and those of acidified buffer solutions were less than 1.0. 95% of the H2S was in headspace with

on the Permeability of Thiobacillus Neapolitan Us to Thiosulphate [PDF]
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 ...

Synergism effect of Thiobacillus Thiooxidans and Thiobacillus Ferrooxidans on the bio-etching
The synergism effect of Thiobacillus ferrooxidans(T.f) and Thiobacillus thiooxidans(T.t) on bio-etching metal material was studied. The rates of bio-etching copper, tin bronze, T10, 40Cr were analysed and compared while T.f, T.t and the mixture of T.f ...
