ABSTRACT
Three strains (14A-2-7(T), 14A-3-1 and 14A-3) of Gram-stain-negative, prosthecate, motile bacteria were isolated from an algal medium supplemented with 10 mg ampicillin l(-1) (w/v), in which the red alga Porphyra yezoensis had been cultured. Based on the 16S rRNA gene sequence analysis, the three isolates formed a cluster with the genus Algimonas of the family Hyphomonadaceae. The sequences of the three isolates had high similarity with those of Algimonas porphyrae 0C-2-2(T) (97.6â% similarity) and Litorimonas taeanensis G5(T) (95.6â% similarity). The DNA G+C contents of the three isolates ranged from 54.3 to 55.0 mol%, which were more similar to that of A. porphyrae 0C-2-2(T) (58.5 mol%) than to that of L. taeanensis G5(T) (47.1 mol%). The DNA-DNA relatedness showed that the three isolates were representatives of the same species (88.1-94.0â% relatedness) and that strain 14A-2-7(T) was a representative of a different species from A. porphyrae 0C-2-2(T) and L. taeanensis G5(T) (1.2-8.6â% relatedness). The phenotypic characteristics of strain 14A-2-7(T) differed by 20 results and 30 results from A. porphyrae 0C-2-2(T) and L. taeanensis G5(T), respectively. The three isolates contained ubiquinone-10 as the predominant quinone and C18ââ1ω7c as the major fatty acid. Based on the polyphasic taxonomic analysis, the three isolates represent a novel species of the genus Algimonas, for which the name Algimonas ampicilliniresistens sp. nov. is proposed. The type strain is 14A-2-7(T) (â=âLMG 26421(T)â=âNBRC 108219(T)). An emended description of the genus Algimonas is also proposed.
