Therefore, objective present work was evaluate antioxidant responses tomato seedlings application via foliar drench nanotubes (CNTs) graphene (GP). Different doses (10, 50, 100, 250, 500, 1000 mg L-1) a...

The growing demand for food production and increasing stress scenarios increase the crucial need sustainable alternatives to achieve increased crop yield quality without affecting environment. use of brown macroalgae, being a renewable resource, is promising option with various application options in agricultural systems, mainly form extracts, direct applications, compost. Brown algae are source active biomolecules minerals that currently used as biostimulants, since they productivity. This...

México es un importante productor en el cultivo de frambuesa (Rubus idaeus L.); sin embargo, la agricultura intensiva plantea serios problemas como disminución fertilidad del suelo, por uso indiscriminado fertilizantes químicos y plaguicidas, se buscan alternativas biotecnológicas favorables al medio ambiente. El objetivo esta investigación fue evaluar efecto bioestimulante con sustancias húmicas rizobacterias variables agronómicas calidad fruto frambuesa. La realizó 2021 invernadero...

Biostimulants are currently essential for agriculture as they increase crop productivity and quality sustainably. The aim of this work was to evaluate the effects biostimulation on application nanochitosan–iodine complexes (nCS-I) tomato plants. Leaf samples were taken analysis total protein content, photosynthetic pigments, antioxidant enzymatic activity, mineral iodine contents, gene expression, shelf life in fruit. catalase (CAT), glutathione peroxidase (GPX), ascorbate (APX), superoxide...

The search for microorganisms able to produce thermostable xylanases with high yield and characteristics desired industrial applications has been strongly encouraged since such enzymes are widely used in large-scale processes. In the present study, thermophilic fungal strains grow at temperatures (≥55 °C) were isolated from maize silage. molecularly identified production of extracellular xylanase by solid-state fermentation using corn cobs as support-substrate material. Species genera...

Functional films based on black chia (Salvia hispanica L.) seed mucilage (BCm) containing Rhus microphylla (Rm) fruit phenolic extract were built and characterized. A hydro-alcohol (HAE) of Rm was incorporated as the bioactive agent due to its noteworthy profile, good antioxidant antifungal activities. The effects BCm concentration (0.2% 0.4%, w/v), HAE incorporation, their interaction with glycerol (1.0%, w/v) calcium chloride (0.05%, films’ physicochemical properties evaluated. filmogenic...

This paper studies the use of fruit peel biomass and waste sludge from municipal wastewater treatment plants in metropolitan area Monterrey, Mexico as an alternative way generating renewable energy. Using a Plackett–Burman experimental design, we investigated effects temperature, inoculum source, C/N (Carbon/Nitrogen) ratio on dark fermentation (DF). The results indicate that it is possible to produce hydrogen using peels codigested with sewage sludge. By adjusting response physicochemical...

Sargassum is a brown macroalga that has become general environmental problem in the Mexican Caribbean. Despite negative effects on beaches, algae contain compounds of biotechnological and agronomic interest. The possibility using sargassum as substrate under liquid media fermentation (LMF) processes will allow obtention bioactive compounds. In this research, five species from Puerto Morelos region were collected beach. samples divided into natural washed Sargassum, total phenolic (TPC),...

Currently, the use of biostimulants in agriculture is a tool for mitigating certain environmental stresses. Brown algae extracts have become one most important categories agriculture, and are derived from different uses positive results obtained under optimal stressful conditions. This study aimed to examine efficacy foliar application hydroalcoholic extract Sargassum spp. two controls (a commercial product based on Ascophyllum nodosum distilled water) with regard growth, antioxidant system,...

Encapsulation technology is used to incorporate a wide range of compounds, which beneficial for protecting and improving the bioactivity plant extracts. In this study, objectives were develop hydroxypropyl methylcellulose microcapsules containing two different extracts from Rhus microphylla fruit namely RmA (obtained by conventional agitation) RmO ohmic heating) using electrohydrodynamic processing. The then characterized through Scanning Electron Microscopy (SEM), ATR-Fourier transform...

In agro-industrial processes, microorganisms that are not pathogenic and generate molecules generally recognized as safe (GRAS). The Aspergillus niger fungus has different industrial applications, being used to produce citric acid 166 other secondary metabolites. objective of this research was optimize a culture medium induce the production kojic (KA) by M4 strain in liquid fermentation process. Four fermentative kinetics were developed flasks, using levels yeast extract (1) 0.05 g/L, (2)...

Fluid mechanics plays a crucial role in everyday life, enabling the selection of accessories, materials, and various components essential for system through which fluid flows. Pressure drop stands out as one most relevant factors design flow systems. However, analytical experimental physical methods can increase these analyses' costs time. Hence, this study, statistical tools are employed to carry specific experiments supported by numerical simulation, aiming comprehend pressure behavior it...

El uso de bioestimulantes es una alternativa en la producción plantas que permite aumentar el crecimiento y vigor. objetivo del trabajo fue evaluar aplicación complejos nanoquitosán-yodo (NPsCs-I) desarrollo tomate. La los tratamientos forma foliar cada 15 días. Se evaluaron variables crecimiento, vigor rendimiento las plantas. Los resultados muestran solamente para diámetro tallo se presentaron diferencias significativas con respecto al testigo absoluto (T0); aumentando aplicar NPsCs-KIO3...

Selenium (Se) is an essential element of the human diet. Therefore, it necessary to implement Se in selenium-deficient soils and nutrient solution soilless system culture. Although not considered as for plants, provides benefits at level redox metabolism, increasing resistance plants various stress factors. The increase availability Se, with use biopolymer complexes, was sought Lactuca sativa var. Great Lakes, grown substrate pots treated SeO2 (5 mg Se/plant), chitosan-polyacrylic acid...
