Isolation of phosphate solubilizer fungi from Araza rhizosphere

Isolation of phosphate solubilizer fungi from Araza rhizosphere

Araza is an eatable plant, original from the Amazon region which has been describedas a promising species for commercialization (Quevedo 1995). This plant has highproductivity even in low content phosphate soil but the presence of phosphatesolubilizazing microorganisms may contribute to increase this element availability.In this study we report the isolation and characterization of solubilizing fungiprocessed using the soil washing method, from soil samples were Araza is cultivated attwo regions in Guaviare, Colombia. Eighteen isolates of fungi capable of solubilizingphosphate were obtained from 2 different sources. The most importat species that solubilized phosphate from calcium were Trichodermaaureoviride, Aspergillus aculeatus,Trichodermastrain 1 y Trichodermastrain 2 and for phosphate from iron: Aspergillus oryzae,Paecilomycesstrain 3, Gongronella butleri& Fusarium oxysporum

El frutal muestra unaelevada productividad aún en suelos con muy bajo contenido de fósforo. La presenciade microorganismos solubilizadores de fosfatos podría contribuir a aumentar la dispo-nibilidad de este macroelemento. Dado que no se han publicado estudios al respecto,durante esta investigación se realizó el aislamiento y la caracterización de hongos so-lubilizadores a partir de 12 muestras de suelo en cultivos de Arazá, procedentes de 2Unidades Fisiográficas (paisajes) del departamento del Guaviare (Colombia), utilizandoel método de lavado de suelo. Se obtuvieron 18 aislamientos de hongos a partir de1.152 agregados de suelo, los cuales demostraron capacidad de solubilizar fosfato nodisponible, procedente de 2 fuentes diferentes (hidrogenofosfato de calcio y fosfato dehierro III hidratados). Los principales solubilizadores del fosfato de calcio fueron Trichodermaaureoviride, Aspergillus aculeatus, Trichodermacepa 1 y Trichodermacepa 2 y para el fosfatode hierro: Aspergillus oryzae, Paecilomycescepa 3, Gongronella butleriy Fusarium oxysporum.
