description It has been demonstrated that applying bio-products based on native rhizosphere micro-organisms in agriculture increases crop productivity. Working with native strains also improves their biological feasibility. Some microbial genera associated with the improved corn variety Francisco were isolated from Nitisol Rhodic, Cambisol Eutric-Humic and Cambisol Eutric soil from different Cuban regions using three isolation methods: the convencional method, the spermosphere model and the microcosm model. The isolated micro-organisms were classified by us­ing classic techniques. The results showed that Pseudomonas, Azospirillum, Azotobacter, Bacillus and Streptomyces were part of the corn rhizosphere microbial community structure, constituting Pseudomonas, this being the most promi-nent populación. All three evaluated isolation methods were suitable for obtaining typical microbial populations; however, the Spermosphere and Microcosm Models were seen to be superior for this purpose as they allow micro-organisms able to live at the expense of crop's exuded roots to become isolated in plant-bacteria interaction. Key words: rhizosphere, corn, spermosphere model, microcosm model, pseudomona

Key words: rhizosphere, corn, spermosphere model, microcosm model, pseudomonaSe ha demostrado que la aplicación de bioproductos a partir de microorganismos rizosféricos en la agricultura, provoca incrementos en la productividad de los cultivos. Si se trabaja con cepas nativas aumenta la factibilidad biológica de los mismos. Esta investigación se realizó con el objetivo de determinar algunos géneros microbianos asociados al cultivo del maíz variedad Francisco mejorado en suelos Nitisol Rhodic, Cambisol Eutric-Humic y Cambisol Eutric procedentes de diferentes localidades cubanas. Para ello se emplearon tres métodos de aislamiento: Método Convencional, Tubos Espermosféricos y Modelo Microcosmos. Los aislados fueron clasificados mediante la utilización de técnicas clásicas. Los resultados obtenidos demostraron que los géneros Pseudomona, Azospirillum, Azotobacter, Bacillus y Streptomyces forman parte de la comunidad microbiana de la rizosfera del cultivo del maíz en las condiciones estudiadas, constituyendo Pseudomonas el género dominante. Los métodos de aislamiento emplea­dos resultaron adecuados para la obtención de representantes típicos de las poblaciones microbianas en estudio, demostrándose la superioridad de los Tubos Espermosféricos y el Modelo Microcosmos para estos fines, ya que los mismos permiten aislar los microorganismos capaces de vivir a expensas de los exudados radicales del cultivo, en la interacción planta-bacteria.
