Energy production in constructed wetlands is a little-known field, as is the operation of vertical partially saturated constructed wetlands (VPS-CWs) that promote both aerobic and anaerobic microbial interactions. By doing so, bacterial degradation is increased, becoming the main mechanism of pollutant removal in constructed wetlands (CWs). For the first time, the generation of bioelectricity, together with the production of ornamental plants in vertical partially saturated constructed wetlands during the treatment of domestic wastewater, was evaluated. Six VPS-CW systems functioned as bioelectricity generators, where the systems were filled with red volcanic gravel and activated carbon as anode and cathode. Three systems were planted with Zantedeschia aethiopica and three with Canna hybrids plants. The development was measured through mother plants and shoots produced every 60 days. The input and output of each VPS-CW was monitored using control parameters such as BOD5, phosphates (P-PO4), and total Kjeldahl nitrogen (TKN). Bioelectricity, power, voltage, and current measurements were performed every 15 days for a period of 7 months. It was found that the VPS-CWs used as biobatteries in combination with the use of domestic wastewater as a substrate improved the development of the two evaluated plant species and stimulated growth and germination of new shoots. No significant differences were found between the different treatments (p ≤ 0.05). Likewise, an average efficient removal of BOD5 (98%) for both systems without statistical differences was observed (p ≤ 0.05), but for TKN and P-PO4, significant differences (p ≤ 0.05) were found between systems planted with Z. aethiopica (TKN: 65%; P-PO4: 20%) and Canna hybrids (TKN: 69%; P-PO4: 27%). This method of water treatment and bioelectricity production with Canna hybrids was an efficient system that generated a great electric current (140 mA/m2), voltage (750 mV), and electric power (15 mW/m2), compared with those observed in systems with Z. aethiopica (60 mA/m2, 500 mV, 9 mA/m2).

Wetland soils are important stores of soil carbon (C) in the biosphere, and play an important role in global carbon cycles in the response strategy to climate change. However, there areknowledge gaps in our understanding of the quantity and distribution in tropical regions. Specifically, Mexican wetlands have not been considered in global carbon budgets or carbon balances for a number of reasons, such as: (1) the lack of data, (2) Spanish publications have not been selected, or (3) because such balances are mainly made in the English language. This study analyzes the literature regarding carbon stocks, sequestration and fluxes in Mexican forested wetlands (Forest-W). Soil carbon stocks of 8, 24.5 and 40.1 kg cm−2 were detected for flooded palms, mangroves, and freshwater or swamps (FW) wetland soils, respectively, indicating that FW soils are the Forest-W with more potential for carbon sinks (p = 0.023), compared to mangroves and flooded palm soils. While these assessments of carbon sequestration were ranged from 36 to 920 g-C m−2 year−1, C emitted as methane was also tabulated (0.6–196 g-C m−2 year−1). Subtracting the C emitted of the C sequestered, 318.2 g-C m−2 year−1 were obtained. Such data revealed that Forest-W function is mainly as carbon sink, and not C source. This review can help to inform practitioners in future decisions regarding sustainable projects, restoration, conservation or creation of wetlands. Finally, it is concluded that Forest-W could be key ecosystems in strategies addressing the mitigation of climate change through carbon storage. However, new studies in this research line and public policies that protect these essential carbon sinks are necessary in order to, hopefully, elaborate global models to make more accurate predictions about future climate.

El objetivo del presente trabajo fue determinar la carga microbiológica en huevo de traspatio, tipo orgánico e industrial de la región centro-occidente del estado de Veracruz. Se evaluó la presencia de microorganismos patógenos en los tres sistemas de producción y se determinó la calidad microbiológica de cada uno de estos sistemas. Lo cual es de suma importancia considerando que en huevo con alta carga microbiológica, pueden estar presentes microorganismos como Salmonella spp S. enteritidis, etc., los cuales son considerados agentes causales de infecciones entéricas en la población. Aunado a lo anterior, los sistemas de explotación antes mencionados, representan una fuente de ingreso económico relevante para las familias que habitan esta región. Para el análisis microbiológico, se tomaron diferentes muestras de cascaron y de la parte interna (clara y yema). Se evaluó la presencia de Salmonella spp aplicando el procedimiento establecido en la Norma Oficial Mexicana NOM-114-SSA1-1994. Además se realizaron pruebas físicas para evaluar si los defectos físicos en huevo pueden correlacionarse con la presencia de Salmonella spp u otras bacterias. Contribución: Actualmente es poca la información que existe sobre la calidad microbiológica, en huevo proveniente de los diferentes sistemas de explotación que se consumen en la región centro-occidente del estado de Veracruz, particularmente para el sistema orgánico y de traspatio.

Companies require tools for analysis and decision-making, so simulation tools present a competitive advantage to be able to evaluate situations and scenarios that allow establishing properly structured action plans and gather all available information on resources, processes, and elements involved in the operation dynamics. The dynamic simulation offers an integrating vision that allows seeing the impact of external variables on the internal variables of interest to be evaluated as a time function with a systemic approach. This paper aims to visualize and detect the dynamics of the interrelationships that occur between the problems that arise in the process of filling water jugs of a purifying company and the problems at the organizational level, to assess the impact on Productivity. First, the pertinent information was collected in the company together with the opinion of experts in the corresponding areas and based on this develop a model with the main variables of operation of the process and personnel's operational performance that makes up the production system of the company under study. Subsequently, the model was validated to analyze it and draw conclusions that allow us to establish proposals for improvement.

Objectives, methodology: In this paper we evaluate the effect of the substrate type on the physicochemical and physiological parameters of tomato fruits (Solanum lycopersicum) type hydroponic saladette. Fourteen hydroponic substrates of mineral origin were evaluated, and mixtures of the same with the aim of selecting substrates that can satisfy the needs or objectives desired by the producer and allowing the consumer to know a fruit with a better quality reflected by its physicochemical properties such as yield, size, colour, total soluble solids (°Brix), titrated acidity, firmness, ethylene and CO2 production. Contribution Substrates such as tezontle, tepezil and coffee husk are favorable in the cultivation of tomato (Solanum lycopersicum) type hydroponic saladette benefiting some of its quality parameters being the most feasible options for the producer and the consumer. Substrates such as the tezontle with compost, tepezil with vermicompost, sugarcane bagasse with compost, coffee husk with vermicompost and coffee husk with compost are other options to consider for cultivation; while the vermicompost, sugarcane bagasse, tepezil with vermicompost, tepezil with compost and sugarcane bagasse with vermicompost, were the least efficient treatments, redicing the fruit quality parameters.

The feijoa is a fruit tree recently grown in the highlands of Veracruz, Mexico. The objectives of this study were to determine some physicochemical and nutritional characteristics of feijoa fruits harvested in Veracruz and to show that some of these attributes are comparable to those of fruits from other producing areas. Commercial-sized fruits were obtained from eight-year-old trees with a single compost application per year. The total soluble solids, pH and acidity of the pulp, in fruits stored at 4, 12 and 25 °C, were similar to those reported in feijoas cultivated in temperate zones. The carbohydrate, fat, fiber, ash, moisture and protein contents in the pulp differ slightly from those reported in the literature. On the other hand, the concentration of vitamin C was higher in the shell than in the pulp. This is the first information on quality parameters of feijoa grown in Mexico. This crop was appropriately adapted to the environment of a high tropical zone.

Lipoxygenase (LOX) enzyme activity and their putative isoforms were investigated during postharvest life in chayote fruit (Sechium edule Jacq. Sw. cv. “virens levis”). Possible associations of LOX with fruit quality parameters are discussed. Five LOX isoforms were identified (SeLOX‐1 to −5) displaying different activity patterns during ripening and senescence as well as in roots, stems, and leaves. The probable role of SeLOX‐5 as a specific isoform linked to senescence was examined. The highest relative activity of LOX was registered in fruit tissue, followed by leaves, stem, and roots. Correlations were found between LOX and fruit composition variables such as the contents of linoleic (LA) and linolenic (LNA) acids, weight loss, CO2 and ethylene production rates. LOX activity, and LA and LNA concentration decreased from Day 1 to Days 13–17, when early seed germination events became visible, indicating a transition stage between late fruit ripening and early senescence characterized by a deteriorative process. Practical applications Detrimental effects on fruit composition variables such as dehydration, weight loss, wilting, and sprouting symptoms, have been reported as the main causes that reduce the commercial quality and shelf life in chayote fruit and prevent their export to distant markets. To the best of our knowledge, the association of lipoxygenase (LOX) enzymes to non‐climacteric fruit ripening—like chayote—or their loss of commercial quality during prolonged shelf life has not yet been described. This is the first study that explores the role of chayote LOX activity in fruit, identifies various specific LOX isoforms associated to ripening or to the senescence process and provides new evidence that supports the hypothesis that putative LOX isoforms might be related to several postharvest detrimental effects on chayote fruit. This information could be useful to food processors or packers to pursue better profitability and consumer satisfaction.

A healthy lifestyle includes fruits and vegetables consumption. Tomato is one of the most consumed vegetables, although it is susceptible to physical damage through postharvest handling, thus leading to important losses. Softening is an important variable during tomato ripening; excessive softening is undesirable and leads to postharvest losses. TomloxB plays an important role in ripening, mainly in the loss of cellular integrity caused by fatty acids released from the lipid matrix of membranes that initiate oxidative deterioration, which is in turn carried into senescence. In order to increase postharvest life, we produced transgenic tomato plants via Rhizobium radiobacter with tomato lipoxygenase B (TomloxB) antisense constructs under control of the cauliflower mosaic virus (CaMV) 35S promoter. Lipoxygenase activity and firmness were measured in tomato fruit and the fatty acids profile was determined. Transgenic fruits were maintained for 40 days at room temperature in optimal conditions, whereas wild type fruits remained in similar conditions for only six days. Firmness in pink and red stages was significantly lower in wild type fruits than in two transgenic lines. Linolenic acid was the most important fatty acid consumed by lipoxygenase in both turning and pink stages of ripening. Lipoxygenase activity was smaller in transformed fruits in comparison with the wild type. These results suggest that silencing the TomloxB gene promoted significant changes in the physiology of transformed tomatoes, being the increase in postharvest life the most important.

In terms of color, firmness, respiration, and ethylene production during the postharvest period, ripening is here characterized for the first time in the fruit of Persea schiedeana Nees. The results show a respiratory peak (respiratory climacteric) and an ethylene production peak, indicating that the fruit of P. schiedeana can be classified as climacteric. The fruit ripened rapidly, and senescence effects appeared 5 days after harvest. Together with appreciable weight loss during the postharvest period, this makes the fruit very perishable. Preliminary values for quantitative ripening indices are provided (fruit firmness, color lightness, hue angle, and chroma).
