Blue light inactivates E.coli, but mechanisms are hidden in the dark

Seminar by Connor Lawrence, Sebastian Waechter and Beatrix Alsanius.

Blue light causes lifestyle changes in some non-phototrophic bacteria. These may lead to impaired or changed nutritional preferences, inactivation or cell death.

We were specifically interested how this applies to one of our favourite pets, E. coli, and did a systematic review and meta-analysis. We found, that E. coli may be killed, but there is quite a bit to go towards more evidence. To our surprise, there are quite some methodological weaknesses in many of the published studies.
