Title A name given to the resource Producción de un biofertilizante a partir de un aislamiento de Azotobacter nigricans obtenido en un cultivo de Stevia rebaudiana Bert Creator An entity primarily responsible for making the resource Daniel Borda-Molina, Juan Manuel Pardo-García, María Mercedes Martínez-Salgado, José Salvador Montaña-Lara Description An account of the resource Bio-fertilizer production from an isolate of Azotobacter nigricans obtained from a plantation of Stevia rebaudiana Bert. Objective.To isolate nitrogen fixing bacteria to be used in a fertilization regime of an organic agriculture program. Materials and methods. Theisolation of nitrogen fixing bacteria was done in an Ashby-benzoate medium from soil of a Stevia rebaudiana plantation. Isolates identifiedas Azotobacter nigricans were evaluated by their growth kinetics and the strain with the fastest growth was used for the production of abiofertilizer by discontinuous fermentation. The preliminary evaluation of the biofertilizer was done by its inoculation into t hree ridges ofa plantation of S. rebaudiana and yield determination was based upon biomass production and glycoside concentration. Results. Twoisolates (A5 and A6) were identified as A. nigricans based on their phenotypic and genotypic characterization. Isolate A5 was selected forpreparing the biofertilizer because it showed a better stability, pigmentation, a faster growth rate (0.1405 h-1 exponential phase of 18 hours)and an average IAA production of 38.4 mg/ml after 150 hours. The bio-fertilizer was obtained in milk medium with a cell concentration of4x1012 CFU/ml. Conclusions. The preliminary field evaluation showed a positive correlation between the increase of the glycosideconcentration in the leaves of S. rebaudiana and a higher production of biomass in response to the bio-fertilizer application.
