It is strictly anaerobic, Gram-negative, and in the form of short rods. It is positive for α- and β-galactosidase, β-galactosidase 6-phosphate, α- and β-glucosidase, αα-arabinosidase, β-glucuronidase, α-fucosidase, alkaline phosphatase, leucine arylamidase and alanine arylamidase (Rapid ID 32A). It is positive for aesculin hydrolysis and for acidification from D-glucose, D-lactose, saccharose, D-maltose, salicin, D-xylose, L-arabinose, D-cellobiose, D-mannose, D-raffinose, L-rhamnose and D-trehalose (Api 20A)(Lagkouvardos 2016).

The strain can degrade pectin consisting of polygalacturonan and rhamnogalacturonan. The end products are D-galactopyranuronate and 4-deoxy-L-threo-hex-4-enopyranuronate. Pectin can be depolymerized by esterase activity. β-L-rhamnopyranose can be converted to L-lactaldehyde and dihydroxyacetone phosphate, which can enter glycolysis. Xylose can be converted to D-xylulose 5-phosphate, which can enter the pentose phosphate pathway. Trehalose can be converted to α-D-glucose and β-D-glucopyranose. The latter can be used to form β-D-glucose 6-phosphate, which can enter glycolysis. Melibiose can be converted to α-D-galactose and α-D-glucose. Starch can be degraded to form β-D-glucose 6-phosphate and β-D-glucopyranose, which may enter glycolysis. L-glutamine can be converted to L-glutamate, which can be dehydrogenized to 2-oxoglutatarate (E.C. 1.4.1.2, Prokka_02968) or converted to ammonium and fumarate. Major cellular fatty acids are anteiso-C_15:0 (33.7%), iso-C_{17:0 3-OH} (15.9%), iso-C_15:0 (13.3%), C_{16:0 3-OH} (7.5%) and C_16:0 (4.8%). The G+C content of genomic DNA is 42.6%.
