Revisión: Posibilidades de bioestimulación con ácidos húmicos en plantas utilizadas para fitorremediación

Abstract

Los ácidos húmicos son una fracción de la materia orgánica humificada con efectos bioactivos que influyen en la fisiología de las plantas, promueven el desarrollo del sistema radical, estimulan el metabolismo primario y secundario, promueven la fotosíntesis, la respiración celular y mejoran la respuesta de las plantas frente a condiciones de estrés; por lo anterior han sido ampliamente estudiados como agentes bioestimulantes, principalmente en plantas de interés agrícola. Sin embargo, no se han explorado opciones de bioestimulación de plantas con otros propósitos, por ejemplo la fitorremediación. El objetivo de esta revisión es analizar evidencias científicas para proponer la bioestimulación con ácidos húmicos como una estrategia para aumentar la remoción de contaminantes a través de plantas fitorremediadoras. En este documento se relacionan aspectos de la estructura y bioactividad de los ácidos húmicos, los conceptos de fitorremediación y bioestimulación, y se analiza como el efecto bioactivo de los ácidos húmicos sobre las plantas podría influir en las diferentes estrategias de fitorremediación. La información analizada permite concluir que los AH se podrían utilizar como pre acondicionadores de plantas que serán utilizadas para la remoción de contaminantes en agua y suelo, a través de fitorremediación, lo cual se puede convertir en una estrategia biotecnológica promisoria para coadyuvar en procesos de tratamiento de ambientes contaminados.
