Zusammenfassung:Considering that little is known about the occurrence of phosphate-solubilizing fungi from areas cultivated with melon, the phosphate solubilization ability of filamentous fungi isolated in these areas was evaluated. Three hundred and eighteen filamentous fungal isolates belonging to 23 genera were evaluated, besides Aphyllophorales and Mycelia sterilia. From those, 52 were able to solubilize P: Aphyllophorales (2), Aspergillus (34), Penicillium (10) and Rhizopus (6). These results will contribute to subsidizing further research regarding the capacity of these fungi to solubilize other sources of phosphate applied to the melon crop, as well as indicate the need for a screening program to select those with higher capacity and potential for solubilization.Considerando que pouco se conhece sobre a ocorrência de fungos solubilizadores de fosfato de áreas cultivadas com melão, foi avaliada a habilidade de solubilização desse nutriente por fungos filamentosos isolados dessas áreas. Foram avaliadas 318 amostras de fungos filamentosos pertencentes a 23 gêneros, além de Aphyllophorales e Mycelia sterilia. Dessas amostras, 52 apresentaram habilidade para solubilizar o fosfato: Aphyllophorales (2), Aspergillus (34), Penicillium (10) e Rhizopus (6). Esses resultados contribuem para subsidiar pesquisas que testem a capacidade desses fungos em solubilizar outras fontes fosfatadas aplicadas na cultura do melão, assim como indicam a necessidade de selecionar isolados com maior capacidade e potencial para solubilização.
