Abstract
El uso del petroleo y sus derivados se ha visto intensificado por la alta demanda energetica actual; esto ha traido consigo el incremento de accidentes ambientales como los derrames de combustibles que afectan negativamente los ecosistemas. En estos ambientes existen microrganismos capaces de sobrevivir a dichas condiciones y utilizar los hidrocarburos de petroleo como fuente de carbono y energia; siendo propuestos en la biorremediacion con un enfoque ecoamigable y costo-efectivo. En este trabajo se aislaron e identificaron cepas bacterianas con potencial biorremediador en medios de cultivo suplementados con petroleo, a partir de una zona contaminada por derrame de petroleo en la Amazonia peruana; tambien se realizo la caracterizacion de la comunidad bacteriana por analisis independiente de cultivo mediante secuenciamiento de proxima generacion dirigido al gen ARNr 16S. Las cepas bacterianas aisladas se identificaron como: Acinetobacter rudis, Enterobacter cloacae, Klebsiella oxytoca, Morganella morganii, Proteus hauseri, Proteus terrae, Proteus vulgaris (2) , Pseudomonas koreensis, Pseudomonas moraviensis, Pseudomonas prosekii y Serratia marcescens (2). En el analisis independiente de cultivo detectaron los filos Proteobacteria y Bacteroidetes como predominantes en agua y suelo contaminados con hidrocarburos; asi mismo, la asignacion taxonomica a nivel de familia destaco los grupos Flavobacteriaceae , Moraxellaceae , Verrucomicrobia y Acetobacteraceae como mas abundantes, ademas de los generos Acinetobacter , Flavobacterium y Geobacter presentes en ambas muestras. De esta manera, se determinaron los principales grupos implicados en la degradacion de hidrocarburos haciendo uso de tecnicas dependientes e independientes de cultivo.
