Sulfur production by obligately chemolithoautotrophic thiobacillus species.
Transient-state experiments with the obligately autotrophic Thiobacillus sp. strain W5 revealed that sulfide oxidation proceeds in two physiological phases, (i) the sulfate-producing phase and (ii) the sulfur- and sulfate-producing phase, after which sulfide toxicity occurs. Specific sulfur-producing characteristics were independent of the growth rate. Sulfur formation was shown to occur when t...
متن کاملTransfer of plasmid RP1 into chemolithotrophic Thiobacillus neapolitanus.
RP1, a broad-host-range incompatibility group P1 plasmid specifying multiple drug resistances, has been transferred into the chemolithotrophic bacterium Thiobacillus neapolitanus. The ability of T. neapolitanus to receive, express, and transmit RP1-encoded antibiotic resistances was examined. The data show that this obligate chemolithotroph can accept, replicate, and express heterologous plasmi...
متن کاملThe amino acid sequence of the cytochrome c-554(547) from the chemolithotrophic bacterium Thiobacillus neapolitanus.
An amino acid sequence is proposed for the cytochrome c-554(547) from the bacterium Thiobacillus neapolitanus N.C.I.B. 8539). It consists of a polypeptide chain of 91 residues, with a pair of haem-attachment cysteine residues at positions 15 and 18. There is similarity in sequence with each of the halves of the sequence of the dihaem cytochromes c4 and with a cytochrome c-554(548) from a haloph...
متن کاملGenetic transformation of obligately chemolithotrophic thiobacilli.
Genetic transformation of Thiobacaillus thioparus auxotrophs to prototrophy was obtained at frequencies of up to 10(-2) when proliferating cell populations were exposed to chromosomal DNA from a nutritionally independent strain of the same bacterium. The rate at which transformation occurred depended on recipient growth rate and could be drastically reduced by depriving otherwise competent cell...
متن کاملAn Iron-Containing Superoxide Dismutase from the chemolithotrophic Thiobacillus denitrificans ˇ+ RT ˇ; Strain
Superoxide dismutase has been purified to homogeneity from aerobically grown Thiobacillus denitrijicarzs strain “RT”. It has a molecular weight of 43,000, is composed of two identical subunits which are not covalently bound, and contains 1.35 atom of iron per molecule. Absorption spectra and amino acid analysis are similar to those of other Fe-superoxide dismutases from bacteria. Aerobically an...
