The Masters Program's Generation and Application of Knowledge

1. Characterization, production, measuring and monitoring secondary metabolites

 In this area, projects are developed related to the extraction, separation, and identification of chemical compounds with bioactivity. General extraction methods are used such as liquid-liquid or solid-liquid extraction. Some of the extraction techniques used imply maceration, Soxhlet extraction, extraction assisted by microwaves or ultrasound, as well as solid-phase microextraction. For separation, ultra and nano membrane filtration methods are used, as well as chromatographic methods of liquids or gases with simple detection. The filtration membranes are used to refine the extracts prior to using the chromatographic techniques. For high-performance liquid chromatography, UV/Visible, refractive index and fluorescent detectors are used. For gas chromatography (GC) flame ionization detectors (FID) and electron capture detectors are routinely used. Identification is done by low- and high-resolution mass spectrometry, infrared spectroscopy (IR), one- and two-dimensional 1H y 13C nuclear magnetic resonance (NMR), and even x-ray diffraction. For quantifying the chemical compounds of interest, the GC-EM-EM and HPLC hyphenated technique with the aformentioned detectors are used. Additionally, organic syntheses for obtaining compounds with bioactivity are carried out, as well as the development and implementation of enzymatic and fermentative methods for the production and monitoring of products of interest.

2. Engineering of Sustainable Biotechnological Processes

 This aims to develop projects that could potentially be used in the food and pharmeceutical industries. It is related to the development of biotechnological processes to reduce the level of organic contaminants from agro-industrial liquid waste, involving physico-chemical and/or biological treatment. Among the physico-chemical treatments is ozonation, while the biological treatments can be aerobic, anaerobic or facultative. These processes are oriented chiefly toward the generation of products of commercial interest, for example: biomass, biogas, probiotics derived from agave and phenolic compounds. The latter are of particular interest, due to the fact that they have a high added value due to their antioxidant activity, which is associated with the prevention of cancer and cardiovascular and neurodegenerative conditions. This line is also associated with the enzymatic production of scents derived from aldehyde and esters.

Administrative processes

El proceso de admisión

 Para la admisión de los alumnos al posgrado MCPNyAl se realiza la secuencia siguiente:
  • Presentación de un examen de conocimientos para su ingreso al propedéutico. Este examen comprende las materias de Bioquímica, Química de alimentos, Matemáticas, y Química Orgánica (se adjunta guía de estudios).
  • Entrevista por parte del comité de admisión, formado por tres miembros del núcleo académico básico (NAB). Donde se evalúan cuatro aspectos: a) Trayectoria académica/profesional y metas profesionales; b) Capacidades personales y habilidades de trabajo experimental; c) Actitudes para trabajo de investigación y estudios de posgrado; y d) Intenciones de inversión de tiempo en el programa de maestría. Se adjunta formato de entrevista. Se publican las fechas para la presentación de exámenes y entrevista.
  • Con base en los resultados del examen de conocimientos y la entrevista se seleccionan los alumnos que participarán en el propedéutico, el resultado se les hace llegar por escrito desde la División de Estudios de Posgrado. En el curso propedéutico se estudian las materias Bioquímica, Química de Alimentos, Matemáticas, y Química Orgánica. Este curso propedéutico es de ocho semanas y se imparte por profesores del NAB, y se evalúan los conocimientos al final de los cursos. El profesor encargado de la materia imparte cursos, analizan artículos científicos relacionados con el tema, según sea el caso. En algunas ocasiones los alumnos llegan a presentar algún tema. Durante este curso propedéutico se realizan exámenes parciales, para un monitoreo del avance académico de los alumnos. Y al final del curso propedéutico se aplica el examen final que permitirá la selección definitiva de los alumnos al programa de posgrado. Esta selección es realizada por el comité de admisión del núcleo académico básico y se analizan los resultados de los exámenes finales las materias y su entrevista. Se redacta un acta de admisión que se hace llegar a la División de Estudios de Posgrado.
  • A los alumnos admitidos se les comunica por escrito el dictamen de admisión, oficio que firma el jefe de la División de Estudios de Posgrado.
