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).

The present study aims to evaluate the effect of thermal pre-treatment (50, 70 Y 90 °C during 1 h) and acid pre-treatment (2.5%, 5% y 10% v/v during 1 h) in anaerobic digestion process of coffee pulp. The methodology consisted of three stages where the waste was obtained and characterized, applied pre-treatments to evaluate the solubilization degree and biogas production. The residue presented a %VS of 91.80, pH of 5.04, total COD 24.26 g/L and soluble COD 14.88 g/L. The solubilization values obtained by applying thermal pre-treatment increased to 0.92-4.98%, while applying acids pre-treatments of 2.6-18.86%. Subsequently, in the anaerobic digestion process, retention time decreased from 23 up to 14 days. The results obtained in this study demonstrate that, pretreatment is significant to increase the percentage of hydrolysis rate, however, the hydrolysis rate percentage cannot be directly related to biogas production in anaerobic digestion.

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.
