The presence of putative sulphur-oxidizing bacteria colonizing the periostracal secretion in the endosymbiont-bearing bivalve Loripes lucinalis

Résumé

Loripes lucinalis. a small bivalve belonging to the Lucinacea superfamily living in reducing coastal sediments, possesses chemoautotrophic sulphur-oxidizing bacteria in its gill. Here, a population of putative sulphur-oxidizing bacteria is described colonizing the bivalve's inner periostracal secretion. The bacteria, were particularly abundant in the vicinity of the anterior and posterior inhalant syphons. Most of the bacteria observed were oval to rod-shaped and measured 3.9 +/- 1.2 mum on average. Histology and negative transmission electron microscopy staining revealed that these bacteria contain refractile spherules similar to those seen in the endocellular gill symbionts of L. lucinalis.
