- ÍtemAcceso AbiertoIdentificación de cepas bacterianas que intervienen en la solubilización del fósforo como base para procesos de Biorremediación(Universidad Católica de Cuenca., 2023) Pinos Saquinaula, Mariela Cristina; Salazar Orellana, Marjorie Jazmín; 0106078660Phosphorus is a fundamental element for plant development; however, its presence in the soil is limited and can be depleted due to various natural processes such as erosion, leaching, and fixation. This study focused on reactivating 67 bacterial strains from the Ruth Moore mycotheque at the Center for Research, Innovation, and Technology Transfer (CIITT by its Spanish acronym). The main objective was to identify bacterial strains capable of solubilizing phosphorus using the specific culture medium known as NBRIP (National Botanic Research Institute’s phosphate growth medium). The results obtained through the halos formed by these bacterial strains allowed the identification of 40 species with the ability to solubilize phosphorus. A literature review was conducted to categorize these species into different groups: 9 species were previously identified by name as phosphorus solubilizers, 19 species were categorized as pathogenic, and three species were reported as non-solubilizers of phosphorus. However, they are used in various bioremediation processes and nine species lacked information regarding their ability to dissolve phosphorus. Notably, this literature review confirmed that Pseudomonas fluorescens stands out as the most effective and widely used in the production of bio inputs.
