| rapidithrix thailandica gen. nov., sp. nov., a marine gliding bacterium isolated from samples collected from the andaman sea, along the southern coastline of thailand. | the taxonomic positions of three strains of marine gliding bacteria, tistr 1736, tistr 1741 and tistr 1750(t), isolated from the southern coastline of thailand were evaluated by using a polyphasic approach. phylogenetic analysis based on 16s rrna gene sequences indicated that the three isolates formed a distinct lineage within the family 'flammeovirgaceae', phylum bacteroidetes, and were related to the genus flexithrix. the dna g+c contents of the isolates were in the range 40-43 mol%. the major ... | 2007 | 17911296 |
| ariakemicins a and b, novel polyketide-peptide antibiotics from a marine gliding bacterium of the genus rapidithrix. | ariakemicins a (1) and b (2), unusual linear hybrid polyketide-nonribosomal peptide antibiotics, were discovered from the fermentation extract of the marine gliding bacterium rapidithrix sp. these metabolites were positional isomers with regard to a double bond and chromatographically inseparable, rendering the structure study on a mixture basis. the ariakemicins were composed of threonine, two omega-amino-(omega-3)-methyl carboxylic acids with diene or triene units, and delta-isovanilloylbutyri ... | 2008 | 18498148 |
| acetylcholinesterase-inhibiting activity of pyrrole derivatives from a novel marine gliding bacterium, rapidithrix thailandica. | acetylcholinesterase-inhibiting activity of marinoquinoline a (1), a new pyrroloquinoline from a novel species of a marine gliding bacterium rapidithrix thailandica, was assessed (ic(50) 4.9 microm). two related pyrrole derivatives, 3-(2'-aminophenyl)-pyrrole (3) and 2,2-dimethyl-pyrrolo-1,2-dihydroquinoline (4), were also isolated from two other strains of r. thailandica. the isolation of 3 from a natural source is reported here for the first time. compound 4 was proposed to be an isolation art ... | 2008 | 19172195 |
