Kurzfassung:
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 H 2 , 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-C 14 : 0 and iso-C 16 : 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 ).
