Desulfosporosinus hippei sp. nov., a mesophilic sulfate-reducing bacterium isolated from permafrost.

The sulfate-reducing strain 343T was isolated from ancient permafrost deposits in Siberia, Russia. Based on 16S rRNA gene sequence analyses, this strain was closely related to Desulfosporosinus species, showing 97.9 % 16S rRNA gene sequence similarity to Desulfosporosinus meridiei DSM 13257T, 97.

EDTA-dependent assimilation of glucose and organic acids by an EDTA-degrading bacterium.

Bacterial strain VKM B-2445 is characterized by ethylenediaminetetraacetate (EDTA) requirement for cell growth. This strain could not grow on glucose and organic acids as the sole sources of carbon and energy, but it was able to metabolize these substrates added to EDTA medium. EDTA initiated assimilation of glucose, succinate, fumarate, malate, and citrate and supplied nitrogen for the biomass production from these substrates.
