Pseudidiomarina piscicola sp. nov., isolated from cultured European seabass, Dicenthrarchus labrax

Strain CECT 9734( T), a Gram-negative, aerobic, chemoorganotrophic bacterium, motile by polar flagella, was isolated from cultured European seabass, Dicenthrarchus labrax, in Spain. It grows from 5 to 42 ºC, 6–9 pH and 1–12% total salinity. Major cellular fatty acids are C(15:0) iso, summed feature...

Sumario:Strain CECT 9734( T), a Gram-negative, aerobic, chemoorganotrophic bacterium, motile by polar flagella, was isolated from cultured European seabass, Dicenthrarchus labrax, in Spain. It grows from 5 to 42 ºC, 6–9 pH and 1–12% total salinity. Major cellular fatty acids are C(15:0) iso, summed feature 9 (C(17:1) iso w9c/C(16:0) 10-methyl) and C(17:0) iso. The genome size is 2.5 Mbp and G + C content is 49.5 mol%. Comparative analysis of the 16S rRNA gene sequence shows that the strain is a member of Pseudidiomarina, with highest similarities with Pseudidiomarina halophila (97.0%) and Pseudidiomarina salinarum (96.9%). Phylogenomic tree based on UBCG program shows P. halophila as its closest relative. ANI and in-silico DDH with other Pseudidiomarina spp. are lower than 87 and 20%, respectively, suggesting that strain CECT 9734( T) represents a new species, for which we propose the name Pseudidiomarina piscicola sp. nov. and CECT 9734( T) (= LUBLD50 7a(T) = LMG 31044( T)) as type strain.
