| Abstract: | The relevant phenotypic traits and phylogenetic relationships between Burkholderia (Pseudomonas) sp. strain LB400 and B. cepacia ATCC 25416T were compared to determine the degree to which these two strains might be related. Strain LB400 degrades chlorinated biphenyls and has been a model system for potential use in the bioremediation of polychlorinated biphenyls, while some strains of B. cepacia are plant and human pathogens. The fatty acid methyl ester profile, sole carbon source utilization, and biochemical tests confirmed that strain LB400 was a member of the genus Burkholderia. The 16S rRNA gene sequence showed that this strain was not as closely related to B. cepacia as previously suspected or to other known pathogens of this genus, but is closely related to B. phenazinium, B. caribensis, B. graminis, and three unnamed Burkholderia spp. not known to be pathogenic.
