Application of electrochemical methods in the removal of organic matter in the juices of the benefit of sisal products: biotechnological alternative for mitigating water pollution in the tributariesAplicación de métodos electroquímicos en la remoción de materia orgánica en los jugos producto del beneficio del fique: alternativa biotecnológica para mitigar la contaminación en los afluentes hídricos
(Universidad Colegio Mayor de Cundinamarca, 2011-12-15)
This research was intended to apply electroanalytical technologies, such as electrocoagulation for removal of organic matter present in sisal juices to reduce the environmental impact generated by age-old cultural practice such as the extraction of the fiber (sisal) of Fourcrea c. In the present study, we evaluated the behavior of chemical oxygen demand (COD) through an electrochemical process under different parameters ...
Effect in Laboratory of Addition of Inorganic Fertilizers Made in Degradation of Hydrocarbon On Contaminated Soil By OilEfecto de la adición de fertilizantes inorgánicos compuestos en la degradación de hidrocarburos en suelos contaminados con petróleo
(Universidad Colegio Mayor de Cundinamarca, 2004-12-15)
At present one of the most important environmental problems is contamination of soil ecosystem by hydrocarbon spilling mainly of oil and its derivates which occurs when oil is explored or transported. Furthermore in Colombia it occurs due to violent assaults made by men outside of law against petroleum infrastructure.To solve this problem there are treatment methods to recover contaminated soil as Landfarming technique, ...
Microbiological Indicators of Contamination of the Water Sources.Indicadores microbiológicos de contaminación de las fuentes de agua.
(Universidad Colegio Mayor de Cundinamarca, 2005-12-15)
Microbiological indicators of contamination of the water sources. The growth of the population on a global scale has increased the levels of contamination. This contamination is related to the spilt one of water of waste of domestic and industrial origin to the water bodies. In case of the residues of domestic origin, the load pollutant is represented by high percentages of organic matter and microorganisms of fecal ...
Pilot Study of Parasites Detection in Fruits and Vegetables Distibuited in the Public and Private Markets of the Bogota CityEstudio piloto de detección de parásitos en frutas y hortalizas expendidas en los mercados públicos y privados de la ciudad de Bogota D.C.
(Universidad Colegio Mayor de Cundinamarca, 2006-06-15)
The diseases transmitted by contaminated foods, they represent a serious problem of health publishes, many microorganisms are able to survive adverse conditions for their development, therefore the fruits and crude vegetables can be contaminated.It is tried with this work, to raise the importance of validating and of implementing the methods to detect parasites in fruits and vegetables during the process of the good ...
Periphytic Algae as Indicators of the State of the Water From an Urban Wetland in Jaboque, Bogotá, D.C., ColombiaMicroalgasperifíticas como indicadoras del estado de las aguas de un humedal urbano: Jaboque, Bogotá D.C., Colombia
(Universidad Colegio Mayor de Cundinamarca, 2006-12-15)
This study implemented the technique of colonization in artificial substrates during a period of seven months (November 2004 through May 2005). In the sector of greater urbanization of the wetland, the most representative group of microalgae were the euglenophytas and cyanophytas, with abundance an average of 20300 of indv/cm2. In the areas with lower anthropic intervention the diatoms were predominant, with an abundance ...
Identification of Salmonella and Escherichia coli in hands and gloves of meat handlers in a slaughterhouse in a municipality in CundinamarcaIdentificación de Salmonella yEscherichia coli en manos y guantes de manipuladores en planta de sacrificio y faenado de un municipio de Cundinamarca
(Universidad Colegio Mayor de Cundinamarca, 2008-06-15)
The presence and consumption of food contaminated with pathogenic microorganisms for humans has a high incidence in developing countries, where the treatment of these diseases has as a consequence an important impact for the public health system. The objective of this project was to investigate the presence of Salmonella and Escherichia coli in 40 samples from the hands of the employees working with cattle, pigs and ...
Isolation of potential oil degrading bacteria in coastal habitats in Cartagena Bay, ColombiaAislamiento de bacterias potencialmente degradadoras de petróleo en hábitats de ecosistemas costeros en la Bahía de Cartagena, Colombia
(Universidad Colegio Mayor de Cundinamarca, 2010-06-15)
In this investigation, bacteria were isolated from 4 habitats in the marine ecosystem adjacent to a petrochemical industry in the Bay of Cartagena (biofilms, neuston, surface water and sediments). In the process, the samples were subjected to a pre-enrichment of a week, to an enrichment of three weeks and a selection of competitive strains, where there were marked changes in the properties of crude oil, such as turbidity ...
Composting Process Optimization of Post-Harvest Product (Cherry) Coffee With the Implementation of Native MicoorganismsOptimización del proceso de compostaje de productos post-cosecha (cereza) del café con la aplicación de microorganismos nativos
(Universidad Colegio Mayor de Cundinamarca, 2010-12-15)
Coffee growing brings the production of large amounts of post-harvest residues such as cherry. This waste causes environmental problems due to contaminated water sources, and generates changes in in the ecosystem if not properly treated. An alternative to this problem is the use of the cherry for the production of compost, reducing production costs. This study aims to reduce composting time of the coffee cherry using ...
