Resumen
Se seleccionaron plantas de chontaduro (Bactris gasipaes Kunth) silvestres crecidas en un suelo de la Costa Pacífica vallecaucana, típicamente ácido y muy deficiente en nutrientes, para realizar la bioprospección de poblaciones bacterianas rizosféricas con capacidad para solubilizar fósforo. Los aislamientos se identificaron por análisis del gen ADNr 16S como Burkholderia ambifaria, Burkholderia lata y Pseudomonas putida, las cuales ya se han registrado como solubilizadoras en muchos ecosistemas, asociadas a la rizosfera en diferentes cultivos de interés comercial.

Wild peach palm (Bactris gasipaes Kunth) plants were selected, grown in a soil of the Valle del Cauca pacific coast, typically acidic and very poor in nutrients, for bioprospecting of rhizosphere bacterial populations with the capacity to solubilize phosphate. The isolates were identified by analysis of 16S rDNA gene as Burkholderia ambifaria, Burkholderia lata and Pseudomonas putida, which has already been registered as solubilizers in many ecosystems, associated with the rhizosphere of different crops of commercial interest.
