| Popis: | 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 |
