摘要：

Hydrocarbons, phenolic compounds and their derivatives are toxic and carcinogenic. They cause adverse effects on human health and the environment. Through the years, the Peruvian jungle has been impacted by constant oil spills in populated areas, causing social conflicts involving the death of people. Unfortunately, there is a not technological solution available for their bioremediation. In this study, we isolated a new bacterial strain (QF50) from oil-contaminated soil collected in La Libertad (north of Peru). The 16S rDNA sequence alignment showed that this strain is P. aeruginosa DSM 50071. We show that QF50 at OD600 of 2.25 triggered substantial degradation of phenol (47.6 %) in 20 hours at pH 8 with 150 rpm of agitation. Our finding, demonstrates that phenol can be degraded by P. aeruginosa QF50 and provide a strong evidence that can be used as a biotechnological tool for rapid bioremediation of wastewater and soils contaminated with phenol in Peru.
