Catabolic Activity of Desulfotomaculum ruminis Bacteria in a Medium Containing Fluorides
نویسندگان
چکیده
The effect of soluble fluorine species in different concentrations on the catabolic activity of Desulfotomaculum ruminis bacteria has been studied. The fluoride concentrations tolerated by and toxic to the bacteria have been determined. The degree of fluorine species toxicity was found to depend on the form in which fluorine is introduced into the medium and increases in the following order: NaF<NH4F<ZnF2< <Na2SiF6<ZnSiF6<CdF2. The results indicate that the difference between the concentrations tolerated by and toxic to the bacteria was very small.

The Effect of Certain Anionic Detergents on the Process of Desulfurication
The effect of sodium dodecylsulphate (SDS), sodium alkilbenzenesulphonate (ABSNa) and sulphosuccinates IOP5 and N5, present in different concentrations, on the kinetics of desulfurication conducted with the use of Desulfotomaculum ruminis bacteria was analysed. As follows from the determined activity of the microorganisms, the presence of SDS and ABSNa inhibits the process of desulfurication. T...

Desulfotomaculum ruminis Campbell and Postgate 1965 is a member of the large genus Desulfotomaculum which contains 30 species and is contained in the family Peptococcaceae. This species is of interest because it represents one of the few sulfate-reducing bacteria that have been isolated from the rumen. Here we describe the features of D. ruminis together with the complete genome sequence and an...

The effect of glutaraldehyde (GA) in different concentrations on microbiological activities of Bacillus licheniformis, Desulfotomaculum ruminis and Thiobacillus ferrooxidans bacteria used in the processes of denitrification, desulfurication and iron (II) oxidation, respectively, has been tested. For the sake of comparison, the effect of formaldehyde (FA) on the activities of the same organisms ...
متن کاملThiosulfate disproportionation by Desulfotomaculum thermobenzoicum.
Desulfotomaculum thermobenzoicum, but not Desulfotomaculum nigrificans, Desulfotomaculum ruminis, or Desulfosporosinus orientis, grew by disproportionation of thiosulfate, forming stoichiometric amounts of sulfate and sulfide; sulfite was not disproportionated. The addition of acetate enhanced growth and thiosulfate disproportionation by D. thermobenzoicum compared to those observed with thiosu...

Extracts of Desulfotomaculum nigrificans, Desulfotomaculum orientis, and Desulfotomaculum ruminis exhibit low levels of inorganic pyrophosphatase but were found to have high levels of pyrophosphate:acetate phosphotransferase. Conversely, extracts of Desulfovibrio gigas, Desulfovibrio vulgaris, and Desulfovibrio desulfuricans Norway 4 were shown to have high levels of inorganic pyrophosphatase b...
