loktanella agnita sp. nov. and loktanella rosea sp. nov., from the north-west pacific ocean.one whitish and four pinkish strains of gram-negative, non-motile, aerobic bacteria were isolated from sea-water and sediment samples collected in chazhma bay (sea of japan, pacific ocean). analysis of 16s rrna gene sequences revealed that these strains belonged to the 'alphaproteobacteria', having highest sequence similarity of about 94-97% with species of the genus loktanella. none of the strains degraded gelatin, casein, chitin, agar, dna or starch and they had limited ability to utilize carb ...200516166733
loktanella koreensis sp. nov., isolated from sea sand in korea.a bacterial strain, ga2-m3(t), isolated from a sea-sand sample in korea, was subjected to polyphasic taxonomic characterization. cells of strain ga2-m3(t) were gram-negative, non-motile, non-spore-forming and short rod- to ovoid-shaped. comparative 16s rrna gene sequencing studies confirmed that the bacterium fell within the radiation of the genus loktanella. similarity levels between the 16s rrna gene sequence of strain ga2-m3(t) and those of type strains of loktanella species with validly publ ...200616957121
against the rules: a marine bacterium, loktanella rosea, possesses a unique lipopolysaccharide.bacteria are an inimitable source of new glyco-structures potentially useful in medicinal and environmental chemistry. lipopolysaccharides (lps; endotoxins) are the major components of the outer membrane of gram-negative bacteria; being exposed toward the external environment they can undergo structural changes and thus, they often possess peculiar chemical features that allow them to thrive in harsh chemical and physical environments. marine bacteria have evolved and adapted over millions of ye ...201020093711
loktanella tamlensis sp. nov., a novel member of the alphaproteobacteria, isolated from seawater.an aerobic, gram-negative, chemoorganotrophic bacterium, designated strain ssw-35t, was isolated from seawater in jeju, republic of korea. cells were motile, short rods; colonies were circular, smooth, convex, translucent and light brown in colour. no diffusible pigment is formed on any of tested media. the temperature and ph ranges for growth were 4-30°c and ph 7.1-10.1. 16s rrna gene sequence analyses showed that the organism belonged to the genus loktanella, with the phylogenetically close re ...201121515703
loktanella sediminilitoris sp. nov., isolated from tidal flat sediment.a gram-stain-negative, non-motile, rod-shaped bacterial strain, designated d1-w3(t), was isolated from tidal flat sediment of the south sea, south korea, and subjected to a taxonomic study using a polyphasic approach. strain d1-w3(t) grew optimally at ph 7.0-8.0, at 25 °c and in the presence of 2 % (w/v) nacl. neighbour-joining phylogenetic analyses based on 16s rrna gene sequences revealed that strain d1-w3(t) fell within the clade comprising species of the genus loktanella, clustering with the ...201323749279
loktanella litorea sp. nov., isolated from seawater.a gram-negative, non-motile, rod-shaped bacterial strain, designated dpg-5(t), was isolated from seawater of the south sea, korea and subjected to a study using a polyphasic taxonomic approach. strain dpg-5(t) grew optimally at ph 7.0-8.0, at 30 °c and in the presence of 2 % (w/v) nacl. neighbour-joining phylogenetic analyses based on 16s rrna gene sequences revealed that strain dpg-5(t) fell within the clade comprising members of the genus loktanella, and formed a cluster with the type strains ...201322389278
