Marine bivalves of the family Teredinidae (shipworms) are voracious consumers wood in marine environments. In several shipworm species, dense communities intracellular bacterial endosymbionts have been observed within specialized cells (bacteriocytes) gills (ctenidia). These bacteria proposed to contribute digestion by host. While microbes studied extensively abundance and distribution digestive system not adequately addressed. Here we use Fluorescence In-Situ Hybridization (FISH) laser...

Here, we describe three endosymbiotic bacterial strains isolated from the gills of shipworm, Bankia setacea (Teredinidae: Bivalvia). These strains, designated as Bs08T, Bs12T and Bsc2T, are Gram-stain-negative, microaerobic, gammaproteobacteria that grow on cellulose a variety substrates derived lignocellulose. Phenotypic characterization, phylogeny based 16S rRNA gene whole genome sequence data, amino acid identity percentage conserved proteins analyses, show these novel may be assigned to...

A cellulolytic, aerobic, gammaproteobacterium, designated strain Bs02 T , was isolated from the gills of a marine wood-boring mollusc, Bankia setacea (Bivalvia: Teredinidae). The cells are Gram-stain-negative, slightly curved motile rods (2–5×0.4–0.6 µm) that bear single polar flagellum and capable heterotrophic growth in simple mineral medium supplemented with cellulose as sole source carbon energy. Cellulose, carboxymethylcellulose, xylan, cellobiose variety sugars also support growth....

Shipworms, bivalve mollusks that burrow into and consume wood, host intracellular gamma proteobacterial symbionts in bacteriocytes located the gill. The bacteria produce cellulolytic enzymes fix nitrogen, were proposed to support host's ability survive on a food source is resistant digestion poor nitrogen. Symbiont genomes reveal surprising number of putative secondary metabolite biosynthesis pathways, leading us propose these may also contribute chemically symbiosis. We observed wood organ...
