Evaluation and identification of metabolites produced by in the interaction with plants and their effect on .

Currently, the use of bio-inputs is increasing due to the need to reduce the use of agrochemicals. However, one of the limitations is to preserve the viability of the living microorganisms, so it is important to find an alternative that allows us to obtain different metabolites to produce it. We evaluated three different interactions (contact, diffusible and volatile compounds) in (At) seedlings with the strain M10 and its filtered secondary metabolites (M10F).

Effective phosphorus removal using transformed water hyacinth: Performance evaluation in fixed-bed columns and practical applications.

This study introduces calcined water hyacinth (CWH), processed at 650°C, as a novel and environmentally friendly adsorbent for phosphorus (P) removal from wastewater. Building on previous findings that identified CWH as a rich source of metal oxides and hydroxides (e.g.

Modeling and experimental analysis of CO methanation reaction using Ni/CeO monolithic catalyst.

In this study, the effect of the cell density of monolithic catalysts was investigated and further mathematically modeled on cordierite supports used in CO methanation. Commercial cordierite monoliths with 200, 400, and 500 cpsi cell densities were coated by immersion into an ethanolic suspension of Ni/CeO active phase. SEM-EDS analysis confirmed that, owing to the low porosity of cordierite (surface area < 1 m g), the Ni/CeO diffusion into the walls was limited, especially in the case of low and intermediate cell density monoliths; thus, active phase was predominantly loaded onto the channels' external surface.

Production of activated carbon from agave residues and its synergistic application in a hybrid adsorption-AOPs system for effective removal of sulfamethazine from aqueous solutions.

Tequila production in Mexico generates large quantities of agave bagasse (AB), a waste that could be used more efficiently. AB has a high cellulose, hemicellulose, and lignin content, which allows its use as a precursor for synthesizing carbonaceous materials. In the present work, the synthesis of activated carbon impregnated with Fe (AG-Fe-II) and Fe (AG-Fe-III) was carried out and evaluated in a hybrid adsorption-AOP (advanced oxidation process) methodology for sulfamethazine removal (SMT).

Synergistic photocatalysis of a hydrochar/CeO composite for dye degradation under visible light.

The synthesis and characterization of a hydrochar/CeO composite along with its evaluation in methylene blue degradation under visible light are presented. The methodology consisted of a single-pass hydrothermal method, having as synthesis conditions 9 h of reaction time, 210 °C, autogenous pressure, and a biomass/CeO ratio of 100:1. The composite characterization revealed good dispersion of CeO in the carbonaceous matrix and significant synergy in the composite activation using visible irradiation.
