Este libro es resultado de un trabajo de investigación para optar al título de Licenciado en Biotecnología. El mismo se centró en la optimización de la producción de sideróforos a partir de bacterias de suelo y ensayar la aplicacion in vitro de estos y de las cepas que los producen, en el control biologico de hongos fitopatogenos. Se partio del aislamiento y seleccion de cepas bacterianas con potencial de producir sideroforos (compuestos extracelulares que solubilizan hierro) a partir de muestras de suelo vitivinicola. Las cepas seleccionadas fueron sometidas a diversas condiciones de cultivo, evaluando diferentes fuentes de carbono y nitrogeno y distintos tiempos de incubacion buscando maximizar la produccion de sideroforos. Posteriormente, los compuestos obtenidos y las bacterias productoras fueron ensayadas contra diferentes hongos fitopatogenos, buscando demostrar la capacidad inhibitoria del crecimiento fungico mediante diferentes ensayos in vitro. Este trabajo propone estudiar tanto a los sideroforos como herramientas prometedoras para el control biologico de hongos, como su produccion en distintos medios de cultivo. El presente trabajo final se ha realizado como una continuacion de los estudios llevados a cabo durante una pasantia y beca de investigacion previas. Al mismo se lo ha estructurado en tres capitulos principales. Cada uno describe los metodos, materiales y resultados de los ensayos realizados, junto con sus respectivas conclusiones.
