Winogradsky column lab page!

Welcome to the Winogradsky column lab page! Students from the Departments of Biological Applications and Technology, University of Ioannina and Icthyology and Aquatic Environment, University of Thessaly, Greece and the Microbiology course, Faculty of Sciences, University of Cádiz, Spain, discuss their findings on Winogradsky columns they constructed!

Καλωσορίσατε στη σελίδα των Winobloggers! Διαδικτυακός τόπος συνάντησης φοιτητών, φοιτητριών και διδασκόντων δύο Τμημάτων από την Ελλάδα: Tμήμα Βιολογικών Εφαρμογών και Τεχνολογιών, Παν/μιο Ιωαννίνων και Τμήμα Γεωπονίας, Ιχθυολογίας και Υδάτινου Περιβάλλοντος, Παν/μιο Θεσσαλίας και ενός από την Ισπανία: Σχολή Θετικών Επιστημών, Πανεπιστήμιο του Cadiz. Παρακολουθούμε, σχολιάζουμε, ρωτάμε, απαντάμε σχετικά με τα πειράματά μας, τις στήλες Winogradsky!

Bienvenidos a la pagina web de los Winobloggers! Aquí los estudiantes y profesores de dos departamentos griegos, el Departamento de Aplicaciones y Tecnologías Biológicas de la Universidad de Ioannina y el Departmento de Agricultura, Ictiología y Sistemas Acuáticos de la Universidad de Thessalia, junto con los estudiantes de Microbiología de la Facultad de Ciencias en la Universidad de Cádiz, se reúnen para observar, comentar, preguntar y responder a preguntas relacionadas con nuestro experimento, la columna Winogradsky.

Winogradsky Column Day 0. Group A5

We added into the column:

- Pond mud: 24.7 g.
- Paper (5 pieces): 0.5 g aprox.
- Yeast: 0.4 g.
- Calcium carbonate: 0.3 g.
- Sea water.

The mud will be the medium of the column where the microorganism will grow. Each component will apport some nutrient for each kind of microorganism.

The paper will be used as the source of glucose by the chemotrophic microorganism but, at the same time, it will only permit to grow the microorganism that can digest the cellulose. The yeast offers a lot of nutrients due to its amount of amino acids. Litotrophic microorganism will grow using the calcium carbonate as the carbon source. It is a saline medium because of the sea water so only will grow microorganism that resist those conditions.

At the end, there will appear different layers. Each colour that appears in the column will mean the growth of different microorganism. At the bottom of the column, will grow anaerobic or facultative anaerobic microorganism. Also, the sun light will be used by autotrophic microorgnanism that synthesize glucose by photosynthesis (cianobacteria).
