Item Aislamiento de nanopartículas implementando membranas de celulosa bacteriana en una matriz simulada(Universidad Antonio Nariño) More Osorio, Laura Liliana; Valderrama Rincón, Juan Daniel; Infante Matenzo, Ricardo AndrésCellulose is a biological molecule that is abundant in nature, obtained from various sources such as plants, fungi, bacteria, and animals. Within Gram-Negative bacteria, such as A. xylinum, bacterial cellulose is produced, which is distinguished by its purity and biocompatible, hypoallergenic, and biodegradable properties. Bacterial cellulose has been used in various applications, including wastewater treatment, air purification, and the creation of selective membranes. Despite these properties, its potential in obtaining nanometric structures and particles of bacterial origin has not been explored, which could be of great biotechnological and pharmaceutical interest.Item Diseño Conceptual de un Sistema de Generación de Energía Eléctrica Sustentable a partir de Metano generado por Digestión Anaerobia: Integración con Procesos Electroquímicos para Tratamiento de Contaminantes en Agua y Análisis Económico(Universidad Antonio Nariño) Barreneche Vásquez, Johan Sebastián; Moncayo Lasso, Alejandro; Valderrama-Rincón, JuanThis study investigated the feasibility of using a biogas electricity generation system to mitigate the high energy costs associated with electrochemical advanced oxidation processes (EAOPs) in the removal of persistent contaminants in water. The energy consumption of the Electro-Fenton (EF) system in the degradation of the Losartan compound and the inactivation of microorganisms was evaluated in two environments: controlled conditions and irrigation water.Item Evaluación de métodos y secuencia de recolección y rompimiento celular en un cultivo microalgal de Chlorella vulgaris y Scenedesmus obliquus.(Universidad Antonio Nariño) Africano Camargo, Edgar David; Valderrama Rincón, Juan DanielA sequence of operations for concentration and cell disruption of a culture of microalgae composed of Chlorella vulgaris and Scenedesmus obliquus was evaluated. For this, biomass growth was carried out in 20 L photobioreactors.Item Biorreactor de digestión anaerobia para la determinación del potencial bioquímico de Metano (BMP)(Universidad Antonio Nariño) Alfonso Pachón, Nixon Darío; Valderrama Rincón, Juan DanielThe generation of both liquid and solid waste from different industries is a current problem that directly affects the environment. That is why anaerobic digestion (AD) is important, since the organic load of pollutants is reduced and biogas is produced, which has concentrations of CO2, H2S and mainly CH4 which can be used as biofuel. The capacity that a substrate has under ideal conditions to produce biomethane is called biochemical methane potential (BMP), for which this work focuses on the construction of an anaerobic bioreactor on a laboratory scale to determine the potential of biomethane. of different residues from the volumetric method by syringe for the measurement of the biogas produced by the digestion of the substrate in a set retention time. For the construction of the device, two prototypes were made, and their efficiency was evaluated to perform the correct detection of gaseous displacement. The device is novel because it only has two modules, its materials are accessible and this allows the reactor to be more easily accessible for laboratories with different purchasing power, unlike the AMPTS II ® (which is the commercial device for the determination of biomethane potential) which has three modules and greater difficulties for access. BMP will be eliminated from plant residues from household sources that were 124 NmLCH4/gSV and microalgae produced by photobioreactors, giving a value of 228 NmLCH4/gSV, values that are close to those found by other studies and the theoretical values calculated stoichiometrically, corroborating in this way the correct functioning of the proposed prototypeItem Diseño de la metodología para la integración de herramientas Open Source aplicadas a la evaluación del comportamiento hidrodinámico de biorreactores usando CFD: Caso de estudio Reactor Metanogénico Escalonado RME(Universidad Antonio Nariño) Otálora Tapiero, Fabián Camilo; Luna Wandurraga, Héctor Javier; Lobo Baeta, Bruno EduardoIn this work you will find a workflow proposal that integrates collaborative and open source tools, specifically Blender, OpenFoam and paraView to model the hydrodynamic behavior of bioreactors, the validation of the created workflow was carried out with a stepped methanogenic bioreactor that has been previously worked on a laboratory scale and developed in a research alliance between UAN and UFOP. The approach and understanding of the tools was carried out under the guidance of practical examples and finally the coupling to a case study, based on the bibliographic search we found that this is a novel work for the area of hydrodynamic modeling in the context of the bioprocesses. Finally, it is concluded on the feasibility of applying the scheme proposed here to increase and facilitate the development of bioprocesses and the prospects of automating simulations in future research by creating Python scripts and including analysis in tools such as R Studio and Power Bi that complement a whole Open Source portfolio, which in comparison with licensed software represents a high investment in licensing and maintenance of updated software.Item Sistema de recuperación de biomasa a escala de laboratorio mediante filtración tangencial(Universidad Antonio Nariño) Infante Matenzo, Ricardo Andrés; Valderrama Rincón, Juan DanielA new functional prototype of a scale bioreactor coupled to a low cost cross-flow filtration system to separate and obtain products of biotechnological interest (biomass). The model has the coupling of a mechanism for measuring temperature, optical absorption and pressure that allow to establish the growth of microorganism cultures in a automated. Development through the design stages links the continuity of experimentation on the growth of microorganism cultures (Saccharomyces cerevisiae), the manufacture of molds and parts from three-dimensional printing (3D), cured with silicone rubber and polyester resin. Integration of elements electronics coupled to software for condition control and recording of behavior of the variables. Thanks to the preliminaries in the elaboration of pieces for the scale bioreactor suitable for sterilization processes and sensor attachment Electronic growth tests were performed from optical measurements and Of temperature; Along with this, it was possible to establish the filtration capacity within the system of flow and pressure relationship. The results obtained show the growth inside the bioreactor at scale of yeast in a homogeneous way. The pressure system succeeded in establishing the behavior under different conditions, with a linear trend in the first 30 mL of sample without the application of prefiltration treatment and shaking; he same linear behavior at 34 mL when the sample passes through the prefilter and shaking and 28 mL of sample when the membrane is washed with hot water coupling improvements in trials. Finally the relationship you have each of the system improvement conditions, making the system have the optimal conditions for the treatment of samples and the washing of membranes.
