“…However, the decrease of soluble P in the PB medium with iron phosphate (strengite) that was recorded in our study could be associated with P absorption by ) and Penicillium (81 µg ml -1 ), and the P concentrations in the medium decreased thereafter (Hernandez-Leal et al, 2011;Coutinho et al, 2012). However, it is possible that the P that was retained in the mycelium is available for uptake by plant roots when the mycelium dies (Kapri and Tewari, 2010).…”

We evaluated the nematicidal potential and phosphate solubilization ability of the fungal species Geomyces pannorum and Paecilomyces carneus, which are associated with the potato cyst nematode Globodera rostochiensis. In a broth medium containing calcium phosphate, the two fungi solubilized between 67%-96% of the insoluble phosphorus that was present in the medium, and in a broth medium containing iron phosphate, the phosphorus that was solubilized by the two fungi ranged between 2%-13%. In a greenhouse experiment, G. pannorum and P. carneus were applied to soil that was naturally infested with G. rostochiensis and planted with Avena sativa. The fungi increased the available phosphorus in the soil by more than 30%, and Paecilomyces carneus also reduced the nematode population by 71%. This study is the first to report on the ability of G. pannorum and P. carneus to increase the available phosphorus in the soil, suggesting that these fungal species may have potential uses in agricultural soils with insoluble phosphorus. Moreover, this study provides a new alternative that contributes to the sustainable management of crops with bio-agents that have dual activity; they increase the available phosphorus in the soil and mitigate plant parasitic nematodes.

-(In vitro solubilization of phosphates by Aspergillus brasiliensis Varga, Frisvad & Samson in the presence of carbon sources). Phosphate-solubilizing fungi play an important role in the availability of phosphorus for plants, as they are capable of reverting insoluble phosphates into soluble forms. However, the solubilization of phosphates may be influenced by the growth of the fungus, which depends on the availability of carbon. The aim of this study was to evaluate the capacity and potential in vitro solubilization of phosphate sources by Aspergillus brasiliensis in the presence of conventional (starch, glucose, and sucrose) and alternative (co-products of winemaking) carbon sources, in the region of Vale do São Francisco, Petrolina, Pernambuco State, Brazil. All carbon sources were assimilated by the specimens, although providing different responses. The co-products of winemaking stimulated fungal growth, providing greater solubilization of phosphates. It is concluded that the co-products of winemaking can be used in agriculture as a viable alternative and a less costly way to produce inoculum of solubilizing fungi and stimulate the growth of indigenous fungi in order to optimize the availability of non-renewable sources. Keywords: filamentous fungi, grape bagasse, phosphorus RESUMO -(Solubilização de fosfatos in vitro por Aspergillus brasiliensis Varga, Frisvad & Samson na presença de fontes de carbono). Os fungos solubilizadores de fosfatos desempenham importante papel na disponibilização de fósforo para as plantas, pois apresentam capacidade de reverter fosfatos insolúveis em formas solúveis. No entanto, a solubilização de fosfatos pode ser influenciada pelo crescimento do fungo, que depende da disponibilidade da fonte de carbono. O objetivo deste trabalho foi avaliar a capacidade e o potencial de solubilização de fontes de fosfato in vitro por Aspergillus brasiliensis na presença de fontes de carbono convencionais (amido, glicose e sacarose) e alternativas (coprodutos da vinificação), na região do Vale do São Francisco, Petrolina, PE, Brasil. Todas as fontes de carbono foram assimiladas pelos espécimes, proporcionando diferentes respostas. Os coprodutos da vinificação estimularam mais o crescimento fúngico, proporcionando maior solubilização dos fosfatos. Conclui-se que os coprodutos da vinificação podem ser utilizados na agricultura como alternativa viável e de menor custo para produzir inóculo de fungos solubilizadores e estimular o crescimento de fungos autóctones, visando a otimização na disponibilização de fontes não renováveis.

This work aimed to isolate and evaluate the phosphate solubilization and phytohormone production abilities of endophytic and rhizosphere fungi belonging to the genus Trichoderma isolated from guanandi (Calophyllum brasiliense Cambess). From the guanandi collected from the field, 12 isolates obtained were grown in potato dextrose broth and supplemented with the phosphate sources, to test their capacity to solubilize phosphates. A strain of Trichoderma asperellum from a commercial inoculant was also used. One isolate was able to solubilize calcium phosphate, 12 solubilized iron phosphate and two solubilized aluminum phosphate. Only the rhizosphere isolates were able to synthesize indole acetic acid (IAA) and none of the rhizosphere or endophytic isolates produced cytokinin or gibberellin. There are Trichoderma isolates that can benefit plant development, both for their known antagonistic ability against phytopathogenic fungi and for their ability to provide phosphates and or to produce phytohormones.
