An endospore stain of the cell Bacillus subtilis showing endospores as green and the vegetative cell as red Phase-bright endospores of Paenibacillus alvei imaged with phase-contrast microscopy. An endospore is a dormant, tough, and non-reproductive structure produced by some bacteria in the phylum Bacillota.
B. subtilis can divide symmetrically to make two daughter cells (binary fission), or asymmetrically, producing a single endospore that is resistant to environmental factors such as heat, desiccation, radiation and chemical insult which can persist in the environment for long periods of time. The endospore is formed at times of nutritional ...
The body also converts niacin and the amino acid tryptophan into NAD, says Martens — these are both found in some foods and available as supplements, but may not be as effective.
Clostridium sporogenes colonizes the human gastrointestinal tract, but is only present in a subset of the population; in the intestine, it uses tryptophan to synthesize indole and subsequently 3-indolepropionic acid (IPA) [5] – a type of auxin (plant hormone) [6] [7] – which serves as a potent neuroprotective antioxidant within the human ...
The term sporogenesis can also refer to endospore formation in bacteria, which allows the cells to survive unfavorable conditions. Endospores are not reproductive structures and their formation does not require cell fusion or division. Instead, they form through the production of an encapsulating spore coat within the spore-forming cell.
It's a traumatic physical and mental experience. There are a lot of unexpected thoughts and feelings that turn your body into unfamiliar territory, and many functions that just no longer feel natural.
Dipicolinic acid composes 5% to 15% of the dry weight of Bacillus subtilis spores. [3] [4] It has been implicated as responsible for the heat resistance of the endospore, [3] [5] although mutants resistant to heat but lacking dipicolinic acid have been isolated, suggesting other mechanisms contributing to heat resistance are at work.

Endospore staining is a technique used in bacteriology to identify the presence of endospores in a bacterial sample. [1] Within bacteria, endospores are protective structures used to survive extreme conditions, including high temperatures making them highly resistant to chemicals. [ 2 ]
