Bacteria produce antifungal compounds that can protect paper from fungal deterioration!
Microbe of the episode
Microbe of the episode: Acetobacter aceti
In this study, scientists tested the ability of the bacterium Lysobacter enzymogenes to protect paper via the antifungal compounds it produces. This first required filtering out the pigments that the bacteria produced, to prevent them from discoloring the paper. Once a method for this filtering was in place, they found the bacterial culture supernatant could significantly reduce fungal growth on various kinds of paper, and protect the paper from staining and degradation.
