Two bacterial species (isolates N and O) were isolated from a paddy soil microcosm that had been artificially contaminated with diesel oil to which extrinsic Pseudomonas aeruginosa strain WatG, had been added exogenously. One bacterial species (isolate J) was isolated from a similar soil microcosm that had been biostimulated with Luria–Bertani (LB) medium. Isolates N and O, which were tentatively identified as Stenotrophomonas sp. and Ochromonas sp., respectively, by sequencing of their 16 S rRNA genes had no ability to degrade diesel oil on their own in any liquid medium. When each strain was cocultivated with P. aeruginosa strain WatG in liquid mineral salts medium (MSM) containing 1% diesel oil, isolate N enhanced the degradation of diesel oil by P. aeruginosa strain WatG, but isolate O inhibited it. In contrast, isolate J, which was tentatively identified as a Rhodococcus sp., degraded diesel oil contained not only in liquid LB and MSM, but also in paddy soil microcosms supplemented with LB medium. The bioaugmentation capacity of isolate J in soil microcosms contaminated with diesel oil was much higher than that of P. aeruginosa strain WatG. The possibility of using isolate J for autochthonous bioaugmentation is discussed.
