Agriculture faces challenges due to the combination of different abiotic stresses where nanotechnology can contribute with promising applications. In this context, several studies report that the application of nanoparticles and nanomaterials positively affects crop productivity through different strategies such as green synthesis of nanoparticles, plant targeted protection through the application of nanoherbicides and nanofungicides, precise and constant supply of nutrients through nanofertilizers, and tolerance to abiotic stress (e.g., low or high temperatures, drought, salinity, low or high light intensities, UV-B, metals in soil) by several mechanisms such as activation of the antioxidant enzyme system that alleviates oxidative stress. Thus, the present review focuses on the benefits of NPs against these type of stress and their possible action mechanisms derived from the interaction between nanoparticles and plants, and their potential application for improving agricultural practices.

Edaphic characteristics are used to determine the viability of places considered as suitable to obtain castor oil. The objectives of this study were to determine the edaphic characteristics and oil content of R. communis, and to evaluate elicitation with salicylic acid (SA) in El Marqués, Querétaro, Mexico. Sampling was carried out in a direct way, selecting sites where castor bean plants were found. Samples of 1.5 kg of soil were taken and 3 clusters of castor bean in a mature state were collected from 21 accessions. The physicochemical characteristics of the soil and oil content of seeds were determined. Finally, 300 plants of the Guanajuatoil variety were planted and elicitated with different SA concentrations under greenhouse conditions in order to determine oil content. The physical analysis of the soil samples indicated dark-colored soils, Mollisol and Vertisol types, with different textures: clay, clay loam, sandy clay loam and sandy loam. Soil chemical analyses showed the following soil characteristics: pH 7.22; electrical conductivity 0.52 dS m-1 ; organic matter 7.17%; cation exchange capacity 26.77; calcium 38.62, magnesium 6.81, sodium 13.41and potassium 6.97 cmol kg-1 ; and nitrogen and phosphorus contents of 16.32 and 54 mg kg-1 , respectively. Castor oil content was higher in clay soils (41.46%). The plants elicited with SA presented oil contents ranging from 28.99% to 52.9%, obtained with 100 and 900 µM. In conclusion, elicitation with SA is an adequate method to increase oil content in castor bean seeds. The locality of El Marqués has good potential for the production of castor oil.

Particularly, whey requires treatment due to their high nutrient content and therefore, its facility to pollute. This treatment also allows its revalorization. Among the main processes that have been reported are the biochemical ones, where anaerobic fermentation is used to produce ethanol, biological processes with microalgae, for the production of fatty acids and some chemicals, and other processes, such as physical or enzymatic. If these processes are integrated, a biorefinery can be designed where the objective is to obtain a diversity of products from a biomass. Some approaches, to the use of dairy wastes in a biorefinery scheme, were reviewed. There is one biological treatment, insects, which have become of interest due to their high conversion efficiency and wide variety of products, such as protein, biofuels or chemicals, generated from waste. Specifically, black soldier fly larvae have been considered for waste degradation. Based on their advantages, the use of insects in a biorefinery scheme using dairy waste as feedstock was proposed.

One of these is the treatment and remediation of water through photocatalytic processes, seeking to reuse wastewater for agriculture. In this paper, Lactuca sativa, Coriandrum sativum, and Capsicum annuum were used as crop models to observe the effects in plant growth and the secondary metabolism of different water qualities and types used in the watering process. Initial results show that the photocatalytic process’s water maintains a pH and ion concentration within the allowed limits, significantly reducing the number of bacteria. Along the growth process, an influence on germination times, appearance of true leaves, maturation, and fruit production depending on the type of water used is observed, obtaining the best results in both growth times and quantity of fruits, for the 50% and 70% disinfected water/tap water (DW/TAW) study groups. Secondary metabolites, such as phenols, flavonoids, and antioxidant activity, were studied to evaluate changes in the vegetables’ composition, showing increased concentration for the disinfected water groups in most specimens. Additionally, no traces of metals and microorganisms were detected, concluding that the crops are viable to be consumed by human beings.

In particular, the cocoa industrial wastes represent a source of usable biomass for the elaboration of new products such as food, livestock feed, cosmetics, and chemical products, and they can even be used for the generation of biofuels. e cocoa industrial wastes include cocoa pod husk, mucilage, and bean shells, which contain compounds of interest for different industries. However, the lignocellulose content of these by-products requires a pretreatment to fully utilize them; thus, different biofuels can be produced, depending on the conversion technology used to obtain the highest biomass yield. Recent studies reported the use of cocoa industrial wastes for the production of solid, liquid, and gaseous biofuels; nevertheless, the most common use reported is as a direct combustion source, which is used to supply the same production plants. erefore, the objective of this work is to carry out a review on the uses of the by-products generated from cocoa for the generation of biofuels, as well as the technological concept applied for the transformation. In addition, the future trends indicate the relevance of using catalysts in production to increase reactions in the conversion of compounds, including the use of statistical models to optimize the processing variables.

Four groups of tadpoles at Gosner stage 24-25 were subjected, during 50 days, to four different treatments: (T) Tadpole culture with temperature control system (25.9 ± 0.34°C) and natural photoperiod (12.25L: 11.75D), (P) artificial photoperiod with a white LED lamp (10L: 14D) and no temperature control system (18.7 ± 1°C), (T/P) the combination of temperature control system (26.01 ± 0.44°C) and artificial photoperiod (10L: 14D), and (N/S) culture with no temperature control system (21.87 ± 1.09 °C) and natural photoperiod (12.25L: 11.75D). The This article is protected by copyright. All rights reserved. experiment was performed under greenhouse conditions. Results showed that tadpoles in treatments T and T/P had the best performance parameters of total length (45.34 ± 1.89 mm for T/P and 44.72 ± 2.13 mm for T), head length (17.15 ± 0.67 mm for T/P and 18.34 ± 0.70 for T), and weight (1.00 ± 0.03 g and 1.14 ± 0.013 g for T/P and T, respectively). In treatments with artificial photoperiod, the use of white light LED lamps had a negative effect on tadpoles by reducing growth. For metamorphosed organisms, the best results were obtained in treatment T/P (25.9%), while treatment P presented the highest survival (36.2%). This experiment demonstrates that having temperature regulation is important to achieve better tadpole growth in intensive rearing systems. The regulation of both variables (T and P) is recommended for metamorphosis activation in the final phases of the tadpole development.

The aim of this work was to assess the effect of irrigation with aquaculture wastewater and salicylic acid addition on the production of phenolic compounds in L. graveolens. L. graveolens plants (14) were irrigated with aquaculture wastewater and (14) using Steiner solution for 28 days; at the same time, salicylic acid was exogenously applied at 0.0 (control), 0.5 and 1.0 mM concentrations in both treatments at 5 and 19 experimental days. The total phenolic content was measured by Folin–Ciocalteu, the flavonoid content was determined by the aluminum chloride method, and the antioxidant capacity was measured by DPPH and FRAP assays. The results showed an increase in the total phenolic and flavonoid content in plants irrigated with aquaculture wastewater solution (17.25 ± 2.35 to 38.16 ± 4.47 mg eq GA·g⁻1 W). The antioxidant capacity was...
