“…Su actividad enzimática influye sobre el suelo, mejora sus propiedades y reduce la contaminación del medio ambiente (Haney et al, 2015). La actividad hormonal en zonas meristemáticas potencia la capacidad fotosintética a través de un mayor desarrollo foliar (Kumar Enamala et al, 2020). La inducción de mecanismos de defensa sobre las plantas, denominado resistencia sistémica y el consumo de los exudados presentes en diferentes órganos, impiden la proliferación de plagas que afectan al cultivo (Díaz-Franco et al, 2021).…”

Introducción. Soya (Glycine max (L.) Merrill) posee importancia económica y nutricional por sus niveles proteicos y contenido de aceite vegetal de calidad biológica, necesarios para la alimentación humana y animal. Las alternativas microbianas de biofertilización de este cultivo podrían representar una opción para su producción con bajos insumos en condiciones tropicales. Objetivo. Evaluar el efecto de microorganismos autóctonos (MA) como alternativa de biofertilización de G. max en condiciones de bajos insumos de producción. Materiales y métodos. El experimento se estableció en una finca situada en la localidad El Coco, Yara, Granma, Cuba, sobre un suelo Pardo Mullido Carbonatado, durante el año 2021. Se usaron semillas certificadas de G. max cv. Incasoy-27. La siembra se realizó en primavera a una distancia de 0,70 m x 0,04 m. Se utilizaron tres dosis de MA (12, 24 y 36 L ha-1) y un testigo absoluto. Se evaluaron variables del crecimiento, rendimiento y sus componentes. Se utilizó un diseño de bloques al azar; los datos se procesaron mediante ANDEVA, regresión lineal, correlación y análisis de componentes principales. Resultados. Los MA bioestimularon el crecimiento de G. max en un rango de 12 % y 24 %, mientras que el rendimiento se favoreció entre 16 % y 44 %. El análisis de correlación de Pearson señaló que la masa de semillas por planta y la cantidad de vainas por planta, constituyeron las variables más correlacionadas con el rendimiento. Conclusión. Con la inclusión de MA se logró una bioestimulación del crecimiento en longitud de las plantas de G. max cv. Incasoy-27 en comparación con el testigo y el rendimiento agrícola se potenció.

“…BES can be considered as a hybrid electrochemical device, whereas a minimum of one of the electrode reactions (anodic and/or cathodic) is carried out by microorganism/biocatalyst, generally under strictly anaerobic conditions [17,33,34]. They provide the main feature of being functionally reversible with conventional electrochemical systems, i.e.…”

Bioelectrochemical systems (BESs) are a new and emerging technology in the field of fermentation technology. Electrical energy was provided externally to the microbial electrolysis cells (MECs) to generate hydrogen or value-added chemicals, including caustic, formic acid, acetic acid, and peroxide. Also, BES was designed to recover nutrients, metals or remove recalcitrant compounds. The variety of naturally existing microorganisms and enzymes act as a biocatalyst to induce potential differences amid the electrodes. BESs can be performed with non-catalyzed electrodes (both anode and cathode) under favorable circumstances, unlike conventional fuel cells. In recent years, value-added chemical producing microbial electrosynthesis (MES) technology has intensely broadened the prospect for BES. An additional strategy includes the introduction of innovative technologies that help with the manufacturing of alternative materials for electrode preparation, ion-exchange membranes, and pioneering designs. Because of this, BES is emerging as a promising technology. This article deliberates recent signs of progress in BESs so far, focusing on their diverse applications beyond electricity generation and resulting performance.

A microbial fuel cell (MFC) is a type of device which is an electrochemical, after technology that is being to recover electricity from wastewater. This study's objective was to measure the potential difference from sludge collected from El-Sheikh Zayed water purification plant (Egypt in April 2021), isolate and identify bacteria present in sludge: Also, determine the effect of adding some metabolites on such physical and chemical properties. Potential difference measurement showed (192 mV) by using MFC. Pantoea spp., Aeromonas salmonicida, Comamonas testosteroni and Staphylococcus lentus were isolated and identified by biochemical reaction tests. A. salmonicida gave the highest potential difference (13mV). After adding some metabolites separately (albumen, dextrose, gelatin and casein), casein recorded 196Mv, a mixture was done between A. salmonicida and four metabolites measuring 50 mV. Physical and chemical analysis showed that biochemical oxygen demand (BOD) (55.0 P.P.M.), chemical oxygen demand (COD) (112.0 P.P.M.), and many minerals and heavy metals were also detected. Green synthesis of electricity from electrogenic bacteria using wastewater like sludge is a promising way to generate electricity by a cheap method.
