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.
Winogradksy columns

FINAL SCORE
As we can observed, the areas are more distinct than the previous time we saw the column As noted, at the bottom we can still notice a dark area due to anaerobic microorganisms and at the top we can also notice a green area due to aerobic microorganisms.The black coloured area at the bottom of the column is due to the presence of iron sulfide which degrades organic matter thus we can notice that black colour . In addition, a small pick coloured area can be observed in the middle region of the column and that is due to a substance produced by purple sulfur bacteria which are responsible for that pink colour.

How many days after you prepared the column are these observations from?
ReplyDeleteIs it the anaerobic organisms that make the colour? Are they black these bacteria? And the aerobic organisms at the top that are green? what are they?
