Slightly curved rods that are 0.2–0.4 × 1–2 µm and occur singly or in pairs. Motile by peritrichous flagella. Gram-stain-positive. Terminal spore swelling the sporange. Chemo-organotrophic and obligately anaerobic member of the domain Bacteria. Yeast extract (0.01%) is required for growth. Produces methylated sulfides from methylated aromatic compounds (e.g., 3,4,5-trimethoxycinnamate) if sulfide or cysteine is present in the medium with acetate being the only volatile fatty acid produced from this metabolism. External electron acceptors are not used. Mesophilic and neutrophilic.
DNA G+C content (mol%): 57 (HPLC).
Type species: Sporobacter termitidis
Microbial Abundance Data: Sporobacter (Percent of total population with standard deviation [PMID: 22698087])
