Popis: | A search for the organisms responsible for the degradation of biomass of primary producers in Tanatar lakes resulted in the isolation of a novel anaerobic, haloalkaliphilic microorganism, strain Z-710T. The strain grows on proteinaceous substrates (peptides) but not on proteins. A rather limited range of substances of other classes can be utilised together with tryptone but not individually. An interesting physiological feature of the novel strain is a high capacity for hydrogen production (up to 30% v/v) during proteolytic fermentation. Phylogenetic analysis based on the 16S rRNA gene sequence similarity revealed that the organism can be assigned to the previously described genus Proteinivorax. According to its physiological features and the low DNA-DNA hybridisation level of the strain with the type strain of the only previously described Proteinivorax species-Proteinivorax tanatarense Z-910T-strain Z-710T is described here as representing a novel species with the name Proteinivorax hydrogeniformans sp. nov. The type strain is Z-710T (= DSM 102085T = VKM B-3042T). |
