This article presents the results of the adaptative versatility and tolerance of a bacterial consortium made up of 10 bacterial stocks endemic to a contaminated soil coming from an onion farm located near Laguna de Tota, Aquitania, Boyacá, Colombia. This soil has been exposed to the uncontrolled use of nitrogen rich fertilizers. The bacterial consortium from the soil is made up of Bacillus megaterium, Bacillus ...
Evaluation of the use of duckweed as an alternative for post-treatment of domestic wastewater effluent from oxidation ponds.Evaluación de la utilización del duckweed como alternativa de pos-tratamiento de aguas residuales domesticas en efluentes de lagunas de oxidación

In the current study we worked on a laboratory scale a system for post-treatment of domestic wastewater in batch-type reactors in order to evaluate the potential of duckweed to remove organic matter, nutrients and coliforms, using as substrate wastewater from the oxidation ponds of the wastewater treatment system from the Municipality of Valledupar. The lemnaceae that served as inoculums to develop there search were ...
Quantitative Determination of Proteases of Isolated Psychotropic Bacteria in Raw MilkDeterminación cuantitativa de proteasas de bacterias psicrotróficas aisladas de leche cruda
(Universidad Colegio Mayor de Cundinamarca, 2007-06-15)
The general use of refrigeration on raw milk has contributed to maintenain its quality, but has induced the selection of psychotropic bacteria which during its growth produces heat-resistant enzymes responsible, in part, for the deterioration of long-life products. This study was designed for the quantification of proteolytic activity in six microorganisms that correspond to Pseudomonas fluorescens R12 y R13, Pseudomonas ...
