Fluorescent bacteria &


Some archaea (primeval bacteria), which, for example, live in a swamp or bog, can glow. This phenomenon is visible in the microscope.
To make them glow in our laboratory, we change them artificially. Afterwards they light up green or red or blue, just as we want! 

Even the glass flask, which contains them, begins to glow.

Fluorescent bacteria &

archaea (e.g. methanogenic bacteria)

Project description

Methanogenic archaea, which also occur in alpine swamps, are characterized by autofluorescence, which can be observed in microscopes. Bacteria can be genetically engineered to produce fluorescent proteins (green, red, blue fluorescent protein), which can also be observed in a microscope or in a liquid culture.
