Description:
About 500 marine bacterial strains isolated in 1987 during the "Hydronaut cruise" on the East Pacific Rise, from various deep-sea hydrothermal vent samples, were screened for the ability to produce exopolysaccharides (EPS). All the EPS-producing bacterial strains (17) were isolated from alvinellid polychaete samples on metal-amended media containing zinc, cadmium, silver, or arsenste. Sixteen of these strains belong to a same phenon (cluster l formed at 82%) on a strain similarity basis. Many strains of this cluster displayed single or multiple resistance to the 5 metals studied (zinc, copper, arsenate, selenate and cadmium), but correlation with EPS-production was not evident. Strains 1545 and 1582, for instance, gave good EPS-production but appeared to be sensitive to heavy metals.
