“…Coffea arabica is one of the most studied plant in Colombia, and, consequently fungal community associated with coffee was deeply investigated. Soil fungal communities were evaluated in coffee plantations in Colombia and Mexico, selecting areas with different intensities of management and edaphic conditions [46]; special attention was paid to iron and calcium phosphate solubilizer fungi. Among the isolated fungi, the presence of Cylindrocarpon didymum and C. obtusisporum (isolated in Colombia), and Penicillium janthinellum and Paecilomyces marquandii (isolated in Mexico), was discussed for their potential practical use to improve the phosphate bioavailability [47].…”

Although Colombia was one of the first tropical countries where an effort was made to gather mycological flora, contributions to the taxonomy, diversity, and ecology of soil microfungi are still scarce. In this study, the diversity of soil microfungi was studied collecting data from literature according to the Colombian natural regions: Andean, Amazonian, Caribbean, Orinoquía, Pacific, and Insular. The majority of the records comes from the Andean region, the most accessible to research. The other regions have been much less studied, with the Insular one with no data at all. International literature reported, up to now, ca. 300 different species of soil microfungi belonging to 126 different genera and 6 phyla (Ascomycota, Basidiomycota Mucoromycota, Glomeromycota, Mortierellomycota, and Olpidiomycota). Vescicular-Arbuscular fungi were widely investigated with Acaulospora and Glomus, the most recorded genera with ca. 20 species each. Ascomycota was the most diverse phylum with Penicillium, Aspergillus, and Fusarium representing the majority. Mortierella is strongly present in Mortierellomycota, and in the panorama of all recorded fungi, too. The other phyla and genera were less recorded. It is, therefore, evident the need to continue studying the soil microfungi in Colombia to have a better understanding of soil functioning and its ecosystem services.

Antecedentes y Objetivos: La deficiencia de fósforo en los cultivos agrícolas generalmente es atendida mediante la aplicación de fertilizantes. Sin embargo, estas prácticas resultan costosas y causan deterioro al medio ambiente. El uso de bio-productos como los hongos solubilizadores de fósforo constituyen una alternativa promisoria. El objetivo de este trabajo fue aislar y seleccionar hongos del suelo fosfato solubilizadores nativos de Coahuila, México, con potencial para ser utilizados como biofertilizantes.Métodos: El aislamiento de los hongos se llevó a cabo mediante la técnica de filtración de partículas de suelo. La selección de las cepas se realizó en el medio de cultivo de Sundara con fosfato tricálcico; la capacidad fosfato solubilizadora se detectó visualmente mediante la presencia de halos hialinos en el medio de cultivo. La evaluación cualitativa se determinó mediante el índice de eficiencia de solubilización. En la evaluación cuantitativa, los cultivos se incubaron en medio líquido por 25 días y cada cinco se midió el P soluble, pH y biomasa fúngica.Resultados clave: Se obtuvo un total de 271 aislamientos de hongos; de éstos 52.76% proyectaron resultados positivos a la prueba cualitativa de solubilización de fósforo. En cuanto a la eficiencia de solubilización, ésta fluctuó entre 2.06-6.85 unidades. Las cepas Sp. Mz54, Aspergillus sp. 4C19, Penicillium sp. Mu73, Penicillium sp. Mu77 y Penicillium sp. A56 presentaron los mayores índices de eficiencia de solubilización (t<0.005). En la medición cuantitativa, la cepa Penicillium sp. Mu73 solubilizó la mayor cantidad de fósforo (83.26 mg l-1) (t<0.005). De acuerdo con los análisis de regresión, el fósforo aumentó a medida que el pH decreció (r2=0.81).Conclusiones: La cepa Penicillium sp. Mu73 tiene un alto potencial para ser utilizada como biofertilizante ya que promueve un alto contenido de fósforo soluble en condiciones in vitro.

“…Solubilization of inorganic phosphates is gaining greater attention in organic and sustainable agriculture; several soil borne micromycetes have been isolated for this purpose (Hernández-Leal et al, 2011;Hernando-Posada et al, 2012. These isolates can be inoculated directly into the soil as biofertilizers or can be used in bioreactors to solubilize rock phosphates or other inorganic phosphates in the production of P fertilizers (Khan et al, 2014).…”

Phosphorus plays a fundamental role in plant metabolic processes. Lack of phosphorus in agricultural soils is compensated with chemical fertilizers, which increase the cost of production and contaminate the environment. One approach to avoid this situation is the use of P-solubilizing fungi as biofertilizers. In this study, the solubilization of Ca3(PO4)2 by five native soil-borne micromycetes (SBM) isolated from the rhizosphere of Carica papaya plants was evaluated. The significant nutritional factors involved in the solubilization of Ca3(PO4)2 by Penicillium hispanicum were determined through a Plackett-Burman experimental design (PBED). Both Penicillium SP1 (108.5 mg/L) and P. hispanicum (106.5 mg/L) solubilized 100% of Ca3(PO4)2 at six days of culture. All studied SBM decreased the pH of the culture mediumfrom 4.15 (control) to <2.45. The PBED revealed that the solubilization of Ca3(PO4)2 by P. hispanicum was significantly influenced (P < 0.05) by low values of MnSO4 (0.002 g/L), (NH4)2SO4 (0.25 g/L) and pH (4.0) and a high amount of Ca3(PO4)2 (0.75 g/L). Total protein content was influenced significantly (P <0.05) by low amounts of glucose (5.0 g/L), yeast extract (0.25 g/L), inoculum (1×105 conidia/mL) and pH (4.0) and high amounts of MgSO4 (0.15 g/L), FeSO4 (0.003 g/L) and Ca3(PO4)2 (0.75 g/L). Meanwhile, biomass production was significantly (P < 0.05) influenced by a high level of glucose (15.0 g/L) and inoculum amount (1×107 conidia/mL). In conclusion, P. hispanicum is a good candidate for further field experiments to test Ca3(PO4)2 solubilization in poor soils that lack Cand N sources.
