Reduced Antibiotic Resistance in the Rhizosphere of in Mercury-Contaminated Soil Mediated by the Addition of PGPB.

The emergence of antibiotic resistance (AR) poses a threat to the "One Health" approach. Likewise, mercury (Hg) pollution is a serious environmental and public health problem. Its ability to biomagnify through trophic levels induces numerous pathologies in humans.

Plant growth promotion of the forage plant Var. Orden Dorado using sp. nov. and sp. nov. added over a valorized agricultural biowaste.

Introduction: The overexploitation of natural ecosystems and the evolution of climate change currently force us to design new strategies for more sustainable agronomic uses. The recovery of plant residues, as an alternative to agrochemicals, can help alleviate these problems, for example, through its use for the synthesis of biofertilizers. In this work, the effect of the organic fertilizer matrix ORGAON from the valorization of horticultural waste is tested, to which two strains of bacteria (and their consortium) are added (SAICEU11 identified as and SAICEU22 identified as ), selected for their demonstrated ability to promote plant growth (PGPB), on the lupine forage plant ().

Valorization as a biofertilizer of an agricultural residue leachate: Metagenomic characterization and growth promotion test by PGPB in the forage plant (alfalfa).

The abuse of chemical fertilizers in intensive agriculture has turned out in the contamination of ground and the soil on which they are applied. Likewise, the generation, storage, and destruction of plant residues from the agri-food industry poses a threat to the environment and human health. The current situation of growing demand for food implies the urgent need to find sustainable alternatives to chemical fertilizers and the management of agricultural waste.

Oxidative stress protection and growth promotion activity of sp. nov., in forage plants under mercury abiotic stress conditions.

SAICEUPSM strain was isolated from soils in the mining district of Almadén (Ciudad Real, Spain), subjected to a high concentration of mercury. Using the plant model of lupinus, the strain was inoculated into the rhizosphere of the plant in a soil characterized by a high concentration of mercury (1,710 ppm) from an abandoned dump in the mining district of Almadén (Ciudad Real, Spain). As a control, a soil with a minimum natural concentration of mercury, from a surrounding area, was used.
