Carbamazepine (CBZ), a widely consumed psychotropic pharmaceutical, is one of the most frequently detected pharmaceutical active compounds (PhACs) in water bodies. Its removal has become an issue from human health and environmental risks point view, due to its latent recalcitrance toxicity properties. The oxidative carbamazepine aqueous medium been investigated by electrooxidation processes using Ti/PbO2 Ti/BDD circular anode electrodes presence NaSO4 as electrolyte batch electrochemical...

A nivel mundial, el trigo es uno de los cereales más utilizados en la alimentación humana y México ocupa segundo lugar producción después del maíz. Sin embargo, su productividad se ve afectada por baja eficiencia fertilizantes químicos pérdida nutrientes suelo, lo que provoca problemas ambientales. Es necesario buscar alternativas para reducir uso inorgánicos mantener o mejorar rendimiento cultivo sin afectar calidad grano. Este estudio calibró validó modelo simulación AquaCrop desarrollo...

In the Yaqui Valley, Mexico, current and estimated annual growth rate of durum wheat (Triticum turgidum L. subsp. durum) yield is insufficient to satisfy food demand that world will be facing by 2050. Furthermore, besides high doses fertilizers applied in this region, nitrogen-use efficiency (NUE) remains low (<34.4%). A sustainable strategy reduce use increase crop quality native plant growth-promoting bacteria as microbial inoculants. This study was performed under field conditions...

Byproducts of tomato are known to include phenolic compounds but have not been studied in depth. In this study, the compositions (stem, leaf, root, and whole plant) two cultivars, Pitenza Floradade, were analyzed by HPLC-DAD. parallel, antiviral effects crude extracts on viral surrogates, bacteriophages MS2 Av-05 evaluated. The leaf from varieties showed highest concentration compounds. identified gallic acid, chlorogenic ferulic cafeic rutin, quercetin, they represented 3174.3 1057.9 mg/100...

Papaya seeds (Carica papaya L.), a by-product of the food industry, contain primary metabolites and offer secondary health benefits, but are often considered waste with no value. Therefore, aim this research was to optimize extraction process polyphenols from L.) maximize their antioxidant activity using response surface methodology (RSM). A design experiment (DOE) approach applied produce optimum conditions factors such as solvent concentration (0–100%), temperature (30–60 °C), time (1–6...

Abstract BACKGROUND Lactic acid (LA) is used in various industries and produced mainly through lactic fermentation (LAF). The high cost of glucose, a common substrate, major challenge for LA production. Alternatives like fructans from agave are being explored this purpose, including the production probiotic beverages using sap leaves wasted field. This study aims to compare kinetics glucose identify kinetic factors be optimize future use process. RESULTS found that direct fructan by...

The production of marine microalgae provides a sustainable solution for agriculture, acting as biostimulants to enhance seed germination, vigor, and early growth. In the present work, parameters pH, airflow, dilution speed were established produce biomass two species algae (Nannochloropsis gaditana Thalassiosira sp.); in addition, its capacity stimulate germination bean seeds was evaluated. experimental treatments included three concentrations (Cb) both (0.5, 1, 1.5 g·L−1) control (distilled...

BACKGROUND Activated carbon was prepared from wheat straw generated by intensive agricultural activities in the Yaqui Valley (northwest of Mexico), and used as adsorbing material for heptachlor removal aqueous solution. Adsorption experiments were carried out batch mode order to evaluate effects pH, activated concentration on adsorption process. RESULTS The reached efficiencies higher than 97% under neutral acidic conditions. Increasing 1 g L−1 2 promoted an increase efficiency 92% 97%....

Draining soil of the former Lake Texcoco, Mexico with pH > 10.0 and electrolytic conductivity (EC) 100 dS m−1 for 17 years has reduced to 7.8 EC 0.68 m−1. Metagenomic DNA from archaeal community was extracted directly this used as template amplify 16S ribosomal genes by PCR construct gene libraries. Most cloned Archaea were related mesophilic crenarchaeota not-yet-cultured. Sequence phylogenetic analyses these clones identified a group close affiliation ammonia-oxidizing Archaea. The...

A wide diversity of organisms exists in soil. Well-adapted groups can be found extreme environments. great economic and metabolic potential for extremozymes produced by living at environments has been reported. Extreme characteristics such as high salt content pH level make the soil former Texcoco Lake a unique place which not exploited. Therefore, this study, 66 strains from were isolated phylogenetically analyzed using universal oligonucleotide primers. Different genera Kocuria,...

Fresas recubrimiento se utilizaron como control. Frutos tratados fueron almacenados por 15 dias a 5°C evaluaron calidad intervalos 3 dias. tratadas control no mostraron diferencias contenido totales antioxidante. Todos tratamientos redujeron...

Aspergillus ochraceus was isolated from coffee pulp and selected as an interesting hydroxycinnamoyl esterase strain producer, using activity microplate high-throughput screening method. In this work, we purified characterized a new type C A. feruloyl (AocFaeC), which synthesized specifically butyl hydroxycinnamates in ternary solvent system. AocFaeC produced by solid state fermentation, reaching its maximal (1.1 U/g) after 48 h of culture. After purification, the monomeric protein (34 kDa)...
