Parvularcula lutaonensis sp. nov., a moderately thermotolerant marine bacterium isolated from a coastal hot spring.

Strain CC-MMS-1(T), a motile, Gram-negative, orange-pigmented bacterium, was isolated from water samples collected from a rare coastal hot spring at Lutao, an island off the eastern coast of Taiwan. 16S rRNA gene sequence studies showed that the novel strain was closely related to Parvularcula bermudensis HTCC2503(T) (95.1 % sequence similarity). The fatty acid profile was slightly different from P. bermudensis HTCC2503(T). The results of physiological and biochemical tests allowed clear phenotypic differentiation of the novel isolate from P. bermudensis HTCC2503(T). It is evident from the genotypic and phenotypic data that the strain should be classified as a novel species in the genus Parvularcula. The name proposed for this taxon is Parvularcula lutaonensis sp. nov. The type strain is CC-MMS-1(T) (=BCRC 17814(T)=KCTC 22245(T)).
