Efficient biodegradation of petroleum n-alkanes and polycyclic aromatic hydrocarbons by polyextremophilic Pseudomonas aeruginosa san ai with multidegradative capacity
Pseudomonas aeruginosa san ai, an alkaliphilic, metallotolerant bacterium, degraded individual selected
petroleum compounds, i.e., n-alkanes (n-hexadecane, n-nonadecane) and polycyclic aromatic
hydrocarbons (fluorene, phenanthrene, pyrene) with efficiency of 80%, 98%, 96%, 50% and 41%,
respectively, at initial concentrations of 20 mg L 1 and in seven days. P. aeruginosa san ai showed a high
biodegradative capacity on complex hydrocarbon mixtures, the aliphatic and aromatic fractions from
crude oil. The efficiency of P. aeruginosa san ai degradation of crude oil fractions in seven days reached
stage 3–4 of the oil biodegradation scale, which ranges from 0 (no biodegradation) to 10 (maximum
biodegradation). Identified metabolites concomitant with genomic and enzymatic data indicated the
terminal oxidation pathway for the n-alkane degradation, and the salicylate and phthalate pathways for
fluorene biodegradation. Polyextremophilic P. aeruginosa san ai, as a biosurfactant producer with
multidegradative capacity for hydrocarbons, can be used in an improved strategy for environmental
bioremediation of hydrocarbon-contaminated sites, including extreme habitats characterized by low or
elevated temperatures, acidic or alkaline pH or high concentrations of heavy metals
