Microbiologists from the Institute of Food Research have demonstrated how clostridia emerge from spores. This finding could help researchers understand how these bacteria
germinate and go on to produce the toxin responsible for botulism (which triggers food poisoning), or cause food spoilage.
According to the Norwich BioScience Institutes:
According to the Norwich BioScience Institutes:
"Dr
Jason Brunt worked with microscopist Kathryn Cross to produce images of the
stages spores go through during germination. Their images showed that the
spores have an outer covering, called an exosporium, with an aperture at one
end. Closer examination showed that this aperture aligned with a spot on the
spore where it ruptures during germination, and that the newly formed cell
emerges through these holes. This suggests that the spores have polarity that
aligns the structures correctly."
