Description:
Pseudomonas aeruginosa strain WatG was unable to utilize either n-hexatriacontane (C"3"6) or n-tetracontane (C"4"0), which are both insoluble in a mineral salts medium (MSM), as a sole carbon source. However, when C"3"6 and C"4"0 were added to MSM containing crude oil, more than 25% of each of the compounds was degraded by this strain after 2 weeks at 30^oC. These results demonstrate that P. aeruginosa strain WatG has the ability to degrade long-chain alkanes up to C"4"0, when they are solubilized by crude oil components.
