Microbial conversion of Selenium: mitigation of abiotic stresses

Abstract

Selenium (Se) is a vital mineral element in human health to prevent risk of many infections (Guo et al. 2023). Selenium’s critical role in human health and well being is well recognized, as it serves as a key constituent of 25 selenoproteins. Crop plants are the richest primary sources providing dietary Se to humans and soil is the main Se source of the plant (Liu et al. 2021). The primary sources of soil Se are volcanic eruptions and derivatives of anthropogenic activities and are crystal or solid forms. The dissociation and dissemination of Se from the primary root sources are important biogeochemical events of soil biogeochemical properties such as Se mobility and bioavailability and Se uptake by plants (Li et al. 2017). Se mobility and bioavailability determined by the redox potential and methylation-demethylation processors, mediated by soil properties, soil organic matter content and microbial activities (Guo et al. 2023) ·
