| dc.description | The study evaluates plate count as a method to determine the viability of symbiotic nitrogen-fixing bacteria in biofertilizers used in agricultural systems, particularly in oil palm cultivation. A methodology based on serial dilutions and inoculation on selective LMA medium is described, allowing the quantification of colony-forming units (CFU) corresponding to metabolically active microorganisms. Through a case study, the microbiological quality of five commercial biofertilizers was analyzed, revealing differences between the concentrations declared by manufacturers and those obtained experimentally. The results confirm that the method is reliable, reproducible, and suitable for quality control of bioinputs. It is concluded that its implementation contributes to ensuring the agronomic effectiveness of biofertilizers and supports more sustainable agricultural practices based on biological nitrogen fixation. | en-US |

Se describe una metodología basada en diluciones seriadas y siembra en medio selectivo LMA, que permite cuantificar unidades formadoras de colonias (UFC), correspondientes a microorganismos metabólicamente activos. A través de un estudio de caso, se analizó la calidad microbiológica de cinco biofertilizantes comerciales y se evidenciaron diferencias entre las concentraciones declaradas por los fabricantes y los recuentos obtenidos experimentalmente. Los resultados confirman que el método es confiable, reproducible y adecuado para el control de calidad de bioinsumos. Se concluye que su implementación contribuye a garantizar la eficacia agronómica de los biofertilizantes y respalda prácticas agrícolas más sostenibles basadas en la fijación biológica de nitrógeno. | es-ES |
