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.

UCA_7B,8B_1: Day 89

Winogradsky column- Day 89

Group 7B (Lucas Garín Ortega and Alba Mejías Gallardo)
Group 8B (Laura Lucena del Amo and Noelia Moares Fernández)


The last time we visited our columns, the one made by group 8B, wich was kept in the light, had the following microorganisms:

·        At the bottom of the column, there was a black layer wich means that there are anaerobic microorganisms that breath with sulphate. The bubbles in thar área, are from H2S, and they are dur to thet breathing.
·        Also, there was a few orange layers wich means that photoeterooganotrophs had been proliferated.

The main diference between the last time we visited our column and this is that there are more orange layers and they are bigger.


After a few weeks we visited our column, the one made by group 7B, for the last time and observed the following:
·   The water that remains on the surface is still clear, so aerobic microorganisms
    have not proliferated

·   The clear layer previously found in the middle of our column has decreased.
    The bottom of the column has become a lighter color, and around this change,
    numerous cracks are found due to gases. These are due to the respiration of the
    microorganisms that are proliferating.

·   Finally, the orange layer appreciated on the surface has increased.
