Spores in microbiology
WebReproduction. Asexual reproduction occurs in the fungi when spores form by mitosis. These spores can be conidia, sporangiospores, arthrospores (fragments of hyphae), or chlamydospores (spores with thick walls). During sexual reproduction, compatible nuclei unite within the mycelium and form sexual spores. Sexually opposite cells may unite ...

Our data … WebSome bacteria can produce toxins that in sufficient doses cause foodborne illness (e.g., botulism). Toxins can be produced by spore-forming bacteria, but only in the vegetative state. Suppressing reactivation to the vegetative state, then, is important in ensuring food safety in many processes. Some non-spore forming bacteria, like Staphylococcus
