    Aislamiento de Gluconacetobacter a partir de cultivos de caña
    (2011-10) Restrepo Franco, Gloria María; Gaviria, Jennifer; Sánchez Toro, Óscar Julián
    Samples were collected from leaves, stem and roots of sugarcane crops located in the municipality of Supía (Caldas, Colombia). The presumptive colonies of the genus Gluconacetobacter were isolated in potato dextrose agar for biochemical testing. Thefollowing biochemical parameters were assessed: Gram stain, fermentation of carbohydrates, catalase, gelatin liquefaction, mobility and citrate use. The results demonstrated the presence of Gluconacetobacter spp. in sugarcane crops located in Caldas. In addition, methodologies for isolation of nitrogen fixing bacteria such G. diazotrophicus were standardized. This will allow the exploration of the potential of these microorganism in order to develop innovative microbial products adapted to local environmental conditions for promoting the growth of different Colombian crops with economic importance.
