Summary We report the presence of M esorhizobium , a genus best known for its nitrogen‐fixing symbiosis with terrestrial legumes, associated with the marine polychaete M eganerilla bactericola ( A nnelida: N erillidae). Abundant epibionts were previously described as coating the exterior of M . bactericola , which is found within the anoxic sulfide‐oxidizing microbial mats of the S anta B arbara B asin, C alifornia, USA . 16 S rRNA investigation of the bacterial community associated with this polychaete discovered the presence of bacteria belonging to M esorhizobium . We identified these bacteria using phylogenetic analyses of 16 S rRNA and three additional functional genes, nifH , atpD and recA , and group‐specific fluorescence in situ hybridization ( FISH ).
