  2. Endospore - Wikipedia

    en.wikipedia.org/wiki/Endospore

    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.

  3. Sporulation in Bacillus subtilis - Wikipedia

    en.wikipedia.org/wiki/Sporulation_in_Bacillus...

    The wrong decision can be catastrophic: a vegetative cell will die if the conditions are too harsh, while bacteria forming spores in an environment which is conducive to vegetative growth will be out competed. [3] In short, initiation of sporulation is a very tightly regulated network with numerous checkpoints for efficient control. [citation ...

  4. Endospore staining - Wikipedia

    en.wikipedia.org/wiki/Endospore_staining

    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 ]

  5. Sporogenesis - Wikipedia

    en.wikipedia.org/wiki/Sporogenesis

    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.

  6. Sporosarcina ureae - Wikipedia

    en.wikipedia.org/wiki/Sporosarcina_ureae

    The cells are coccoid. Cells are 1–2.5 μm. Cell division is carried out in two or three successive planes, such that tetrads or packets of eight or more cells are formed. [4] S. ureae forms endospores (like all species of the genus). The endospores are 0.5–1.5 μm. [5] The species can move using a flagellum.

  7. Spore - Wikipedia

    en.wikipedia.org/wiki/Spore

    Spores can be classified in several ways such as by their spore producing structure, function, origin during life cycle, and mobility. Below is a table listing the mode of classification, name, identifying characteristic, examples, and images of different spore species.

  8. Bacterial cell structure - Wikipedia

    en.wikipedia.org/wiki/Bacterial_cell_structure

    Since the cell wall is required for bacterial survival, but is absent in some eukaryotes, several antibiotics (notably the penicillins and cephalosporins) stop bacterial infections by interfering with cell wall synthesis, while having no effects on human cells which have no cell wall, only a cell membrane.

  9. Clostridium sporogenes - Wikipedia

    en.wikipedia.org/wiki/Clostridium_sporogenes

    Clostridium sporogenes is a species of Gram-positive bacteria that belongs to the genus Clostridium. Like other strains of Clostridium, it is an anaerobic, rod-shaped bacterium that produces oval, subterminal endospores [2] and is commonly found in soil. Unlike Clostridium botulinum, it does not produce the botulinum neurotoxins.
