Efecto de la concentración de surfactante y de la temperatura en la biodegradación de naftaleno, antraceno y fenantreno por Enterobacter sp., Pseudomonas sp. y Stenotrophomonas sp. aislados de un consorcio degradador de HAP

Environmental contamination by polycyclic aromatic hydrocarbons (PAH) is currently a widespread problem. PAHs are produced by incomplete combustion of fossil fuels and other materials. Moreover, PAHs are poorly soluble in water and they present toxic properties. In order to address this problem, surfactants are often used due to they favor the solubility of these hydrophobic compounds. Temperature influences both on the properties of PAHs and the metabolism of microorganisms involved in this process. Enterobacter sp., Pseudomonas sp. and Stenothrophomonas sp., have an efficient degrading capacity of naphthalene, phenanthrene and anthracene at 15 and 25 °C.
