Capacidad para crecer en alcoholes y compuestos aromáticos de bacterias metilotroficas aisladas del humedal. La Mixtequilla, Veracruz

Abstract

Abstract. The growth capability on alcohols and aromatic compounds was assessed for bacteria isolated from water samples of the wetland La Mixtequilla (Veracruz). Methylotrophic activity of bacterial isolates was detected through their ability to grow on a culture medium with methanol as sole carbon and energy source. Isolates were purified before testing their ability to grow on methanol, ethanol, 1-butanol, 2-propanol, toluene and xylene as sole carbon sources. These isolates were catabolically characterized and genetically identified; bacterial growth was detected in all the alcohols and aromatic compounds, at all concentrations which they were assayed; nine of the isolates were genetically identified and five of them were catabolically characterized. The 16S rDNA analysis revealed that they were similar to Tetrasphaera sp., Bacillus pumilus, B. jeotgali, Enterobacter asburiae Klebsiella pneumoniae y Serratia marcescens. These isolates could be useful for bioremediation of environments negatively impacted by human activities
