Pseudomonas cocovenenans, the producer of bongkrekic acid and toxoflavin, has been described previously by us (N.-X. Zhao, M.-S. Ma, Y.-P. Zhang, and D.-C. Xu, Int. J. Syst. Bacteriol. 40:452-455, 1990) in terms of more than 180 phenotypic traits, G+C content, and DNA relatedness. The bacterium conformed to section II of the genus Pseudomonas. Here, its partial 16S rRNA gene sequence was compared with those of Burkholderia spp., and the results verified that P. cocovenenans is a Burkholderia species. On the basis of the phenotype and genetic characteristics, P. cocovenenans is transferred to the genus Burkholderia as Burkholderia cocovenenans comb. nov.
