Ercella succinigenes gen. nov., sp. nov., an anaerobic succinate-producing bacterium.
A novel anaerobic succinate-producing bacterium, strain ZWB(T), was isolated from sludge collected from a biogas desulfurization bioreactor (Eerbeek, the Netherlands). Cells were non-spore-forming, motile, slightly curved rods (0.4-0.5 µm in diameter and 2-3 µm in length), and stained Gram-negative. The temperature range for growth was 25-40 °C, with an optimum at 37 °C. The pH range for growth was 7.0-9.0, with an optimum at pH 7.5. Strain ZWB(T) was able to ferment glycerol and several carbohydrates mainly to H2, succinate and acetate. Sulfur and fumarate could be used as electron acceptors by strain ZWB(T). The G+C content of the genomic DNA was 37.6 mol%. The most abundant fatty acids were iso-C14 : 0 and iso-C16 : 0 DMA. On the basis of 16S rRNA gene sequence similarity, strain ZWB(T) belongs to the family Ruminococcaceae and it is distantly related to Saccharofermentans acetigenes JCM 14006(T) (92.1%). Based on the physiological features and phylogenetic analysis, strain ZWB(T) represents a novel species of a new genus, for which the name Ercella succinigenes gen. nov., sp. nov. is proposed. The type strain of Ercella succinigenes is ZWB(T) ( = DSM 27333(T) = JCM 19283(T)).
