Determinación de la capacidad de adsorción de Pb(II) en solución acuosa por raíces de Typha latifolia (Espadaña). - Carranza, Candy; Figueroa, Luis; Hernández, Alejandro; Hernández, Diego; Medellín, Nahúm
In present study a biomass derived from the root of Typha latifolia (cattail) has been investigated to remove Pb (II) from surface water samples. The effects of various parameters viz. pH biosorbent dosage, contact time and temperature on the biosorption processes were systematically studied. Experimental data were modeled by Langmuir and Freundlich isotherms. It was observed that Pb biosorption best fitted to the Freundlich isotherms.
The biomass of T. latifolia was found to be effective for the removal of Pb with 95% sorption efficiency at pH 5, and thus uptake capacity is 21.85 mg/g of biomass. The physical characterization of root...
Perfil antropométrico de dos equipos universitarios de balonmano femenil. - López, Ricardo; Hernández, Germán; Rangel, Blanca; López Walle, Jeanette Magnolia; Ramos, Isela
An important aspect of working in sports nutrition is the weight change and body composition. Many athletes need to minimize body fat and weight to improve the biomechanics aspects or increase muscle mass to improve performance. For this reason, the aim of our study was to determine the anthropometric profile of handball players of two college teams. They we made 17 basic anthropometric measurements to both teams. Team 1 obtained a mesomorphic-endomorphic phenotype and Team 2 obtained an endomorphic-mesomorphic phenotype. The mesomorphic component is predominant in both teams; therefore, it can be assumed that the skeletal muscle strength in female...
Prevalencia de cepas multirresistentes de Salmonella spp y Escherichia coli 0157:H7 en alimentos crudos en la Ciudad de Puebla. - López, A.; Ruiz, A.C.; Cabrera, C.; León, G.; Tejeda, F.
Gastrointestinal diseases are a problem among Mexican population and worldwide, because they can be transmitted by contaminated food or mismanagement and manipulation. Ignorance of the causal agent of these diseases can result in an incorrect treatment to the patient, the emergence of resistant microorganisms or a complication of the disease that can lead to death. It is for these reasons that the present work is focused on identifying the most common causative agents of gastroenteritis, Escherichia coli O157:H7 and Salmonella spp. in raw food in the city of Puebla, and thus be able to propose measures for the control of...
Obtención de aislados bacterianos de la rizósfera de Typha latifolia (Espadaña) crecida en sitios contaminados con Plomo. - Hernández, Alejandro; Rubio, Jocabed; Carranza, Candy; Álvarez, Claudia; Pacheco Aguilar, Juan Ramiro
Typha latifolia is a plant used in phytoremediation due to its ability to remove heavy metals from impacted sites, and accumulating them primarily in the roots. Plant roots are involved in the absorption of water and nutrients, and in the interaction with rhizosphere microorganisms, such as plant growth-promoting rhizobacteria (PGPR). PGPR promotes plant growth in stress conditions caused by heavy metals, drought, salinity and other adverse conditions in the soil. Regarding T. latifolia interactions with rhizosphere microorganisms is still poorly understood. So in this study the bacterial isolation from T. latifolia rhizosphere was conducted. Isolation of bacteria was performed in...
