Fig. 1From: Ability of the So-Called Obligate Hydrocarbonoclastic Bacteria to Utilize Nonhydrocarbon Substrates Thus Enhancing Their Activities Despite their Misleading NameA phylogenetic tree illustrating the relationships among all the “OHCB” isolated from the Arabian Gulf in our laboratory. The tree is constructed by neighbor-joining method. Numbers at nodes indicate bootstrap values of 2000 resembling; 0.1 denotes the genetic distance. Strains in bold are type strains from the GenBank database; highlighted strains are the “OHCB” used in this study; the remaining are hydrocarbonoclastic strains isolated in our laboratory. Three nonobligate hydrocarbonoclastic species, Microbacterium paludicola, Pseudomonas songnenensis and Arthrobacter phenanthrenivorans were included for comparisonBack to article page
