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 ...

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 ...
