Isolation of a new thermohalophilic Thermus thermophilus strain from hot spring, able to grow on a renewable source of polysaccharide.

A thermohalophilic strain, Samu-Sal, isolated from hot springs of the Mount Grillo (Baia, Naples, Italy) at a depth of 60 m, according to its genotypic analyses is related to Thermus genus and should be classified as a new strain of Thermus thermophilus. Strain Samu-SA1 grew using, as sole carbon source, a polysaccharide extracted from waste industrial tomato process with a yield of 3.5 g l(-1). Strain Samu-SA1 synthesized several alpha- and beta-glycosidases.
