Abstract—
Slow-growing, hard-to-cultivate prokaryotes require special conditions for laboratory cultivation. The difficulty in cultivation may often prevent depositing the new isolates in the culture collections in order to validate their taxonomic status. The sulfate-reducing firmicute “Desulforudis audaxviator” strain BYF, has been isolated from a deep thermal borehole in West Siberia. In this study we showed that decreasing the concentrations of calcium and phosphate, as well as addition of a polyamine spermidine, increased the growth rate and biomass formation by these bacterium.
