Abstract

A yellow-pigmented, Gram-negative, slowly gliding, rod-shaped, strictly aerobic bacterium (UST040801-001T) was isolated from marine sediment. The DNA G+C content was 39.9 mol%. The predominant fatty acids were a15:0, i15:0, i15:0 3-OH, i17:1 ω9c, i17:0 3-OH and summed feature 3, comprising i15:0 2-OH and/or 16:1 ω7c (altogether representing 76.2% of the total). MK-6 was the only respiratory quinone. Flexirubin-type pigments were not produced. Phylogenetic analysis based on 16S rRNA gene sequences indicated that Gramella echinicola KMM 6050T (the only species in the genus) was the closest relative of UST040801-001T, sharing 98.0% sequence similarity. The DNA-DNA relatedness between UST040801-001T and Gramella echinicola KMM 6050T was 13%. Strain UST040801-001T can be distinguished from G. echinicola by means of 11 phenotypic traits. The results of molecular and phenotypic analyses suggested that UST040801-001T represents a novel species of Gramella. The name Gramella portivictoriae sp. nov. is proposed for this bacterium, with UST040801-001T (= NRRL 41137T = JCM 13192T) as the type strain.
