Caracterización de Consumo de Hidrocarburos Totales de Petróleo y Fijación de Nitrógeno Atmosférico por Kribbella sp Nativa del Piedemonte Llanero

Abstract

This study supported phase II of the macro-project "Behaviour of physical, chemical and microbiological characteristics in agricultural soils artificially contaminated with Gasoline and Diesel in the plain footof of the Municipality of Cumaral ( Target)", in determining the consumption of petroleum crude as the only source of carbon, of the Kribbella sp actinomycete strain, while continuing to fix atmospheric nitrogen, an enzyme capacity demonstrated from the insulations made in the first phase of the project. The correlation of the data was obtained, through laboratory testing, through the cultivation in liquid and solid medium, using as the only source of carbon two fuels derived from oil, diesel and gasoline at different concentrations, determining the growth curves with the relationship between cell density versus the presence of total hydrocarbons of oil –HTP-. In order to establish the efficiency of consumption of petroleum products and conservation of the ability to fix atmospheric nitrogen by the native actinomycete of the plain piedemonte.
