Several characteristics, including biochemical, serological, drug resistance and plasmid profiles, of strains isolated from clams in southwestern Spain affected with brown ring disease have been comparatively studied. On the basis of 36 standard physiological and biochemical tests, all strains isolated were included in the genus Vibno and further divided into 6 groups. The groups were different...

Phosphonates represent an important source of bioavailable phosphorus in certain environments. Accordingly, many microorganisms (particularly marine bacteria) possess catabolic pathways to degrade these molecules. One example is the widespread hydrolytic route for breakdown 2-aminoethylphosphonate (AEP, most common biogenic phosphonate). In this pathway, aminotransferase PhnW initially converts...
