摘要： An alginate lyase-excreting bacterium, designated strain HB161718(T), was isolated from coastal sand collected from Tanmen Port in Hainan, PR China. Cells were Gram-stain-negative rods and motile with a single polar flagellum. Its major isoprenoid quinone was ubiquinone 8 (Q-8), and its cellular fatty acid profile mainly consisted of C-1(6:1)omega 7c and/or C-16:1 omega 6c, C-18:1 omega 6c and/or C-18(:1) omega 7c. C-16:0 omega 7c, C-16:0, C-17:0 10-methyl and C-16(:0) N alcohol. The G+C content of the genomic DNA was 44.1 mol%. 165 rRNA gene sequence analysis suggested that strain HB161718(T) belonged to the genus Alteromonas, sharing 99.5, 99.4, 99.2, 98.9 and 98.5% sequence similarities to its closest relatives, Alteromonas macleodii JCM 20772(T), Alteromonas gracilis 9a2(T), Alteromonas australica H17(T), Alteromonas marina SW-47(T) and Alteromonas mediterranea DET, respectively. The low values of DNA-DNA hybridization and averagenucleotide identity showed that it formed a distinct genomic species. The combined phenotypic and molecular features supported the conclusion that strain HB161718(T) represents a novel species of the genus Alteromonas, for which the name Alteromonas portus sp. nov. is proposed. The type strain is HB161718(T) (=CGMCC 1.13585(T)=JCM 32687(T)).
