title: The naturally transformable marine bacterium WJT-1C formally identified as "Vibrio" is a pseudomonad.
abstract: A marine bacterial isolate, previously identified as Vibrio WJT-1C (ATCC 55351) and used as a model for investigating the process of natural transformation in the marine environment, has been further examined to determine its taxonomic identity. API 20E test strips, phenotypic testing, and flagellar staining had previously assigned the strain to the genus Vibrio, most closely related to V. campbelli. 16S rRNA analysis indicated that WJT-1C was in the Pseudomonas subgroup of the gamma proteobacteria. Bacteriophage typing and natural transformation with chromosomal DNA indicated that it was distinct from previously described marine transforming pseudomonads including Pseudomonas stutzeri strain JM300. The importance and abundance of the Pseudomonas subgroup of the gamma proteobacteria in the environment suggest that these marine strains are well suited as model organisms for describing the process and importance of natural transformation in nature.
