Abstract
A marine bacterial isolate, previously identified as Vibrio WJT-1C (AT CC 55351) and used as a model for investigating the process of natural transformation in the marine environment, has been further examined t o determine its taxonomic identity. API 20E test strips, phenotypic te sting, and flagellar staining had previously assigned the strain to th e genus Vibrio, most closely related to V. campbelli. 16S rRNA analysi s indicated that WJT-1C was in the Pseudomonas subgroup of the gamma p roteobacteria. Bacteriophage typing and natural transformation with ch romosomal DNA indicated that it was distinct from previously described marine transforming pseudomonads including Pseudomonas stutzeri strai n JM300. The importance and abundance of the Pseudomonas subgroup of t he gamma proteobacteria in the environment suggest that these marine s trains are well suited as model organisms for describing the process a nd importance of natural transformation in nature.
