Colonial heterogeneity of Thiobacillus versutus.
In acetate-limited chemostat cultures started with single-colony cultures of Thiobacillus versutus, a mutant appeared after approximately 85 volume changes. The inhomogeneity of the culture was detected by the development of two different types of colonies on agar plates. When a pure culture of the mutant was grown in a chemostat, parent colonies appeared after almost the same period of time. E...
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 کاملSulfur 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 کاملEXAFS analysis of the pH dependence of the blue-copper site in amicyanin from Thiobacillus versutus.
The room temperature Cu K-edge EXAFS (extended X-ray absorption fine structure) spectrum of reduced and oxidized amicyanin, the blue copper protein from Thiobacillus versutus, was measured at low and high pH. The data interpretation was partly based on independent NMR evidence for the occurrence of a ligand histidine protonation at low pH (pKa = 6.9) in the reduced protein. In the oxidized prot...
متن کاملOxidation of Pyrite and Marcasite by Thiobacillus ferrooxidans Bacteria
This paper reports results of studies on the influence of the crystallographic mineral structure on the process of pyrite and marcasite leaching. Kinetic studies show that the crystallographic structure of minerals like FeS2 type does not influence the efficiency of the process.
