Abstract
A heterotrophic, slightly thermophilic,
marine bacterium, designated strain T5054
was isolated from a hot spring on the coast of
Lutao, Taiwan. It was a strictly aerobic,
Gram-negative rod. Cells grown in broth
cultures were non-spore-forming and motile
by means of one to several polar flagella. Pili
were commonly produced from both poles of
the cells. Strain T5054 required sodium ions
for growth, and exhibited optimal growth at
about 45 C, pH 7 and 4% NaCl. It
contained iso-C15:0 as the most abundant fatty
acid and ubiquinone-8 (Q-8) as the only
isoprenoid quinone. Its genomic DNA G+C
content was 63.5 mol%. The strain did not
require either vitamins or other organic
growth factors for growth; it grew on glucose,
mannitol and a variety of organic and amino
acids as sole carbon sources. Characterization
data, together with the results of a 16S
rDNA-based phylogenetic analysis, indicated
that strain T5054 should be classified as a
species of a new genus. The name
Aeromarinobacter lutaoensis gen. nov., sp.
nov. is proposed for this new bacterium. The
type strain is T5054 (= CCRC 17087T = JCM
11179T).
