  2. Sporulation in Bacillus subtilis - Wikipedia

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

    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 ...

  3. Bacillus subtilis - Wikipedia

    en.wikipedia.org/wiki/Bacillus_subtilis

    Bacillus subtilis is a model organism used to study bacterial chromosome replication. Replication of the single circular chromosome initiates at a single locus, the origin ( oriC ). Replication proceeds bidirectionally and two replication forks progress in clockwise and counterclockwise directions along the chromosome.

  4. 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.

  5. Endospore staining - Wikipedia

    en.wikipedia.org/wiki/Endospore_staining

    Endospore stain on Bacillus subtilis.The spore is stained green and the vegetative cell is stained a pinkish red color. Endospore staining is a technique used in bacteriology to identify the presence of endospores in a bacterial sample. [1]

  6. Bacillus - Wikipedia

    en.wikipedia.org/wiki/Bacillus

    B. subtilis is a valuable model for bacterial research. Some Bacillus species can synthesize and secrete lipopeptides, in particular surfactins and mycosubtilins. [9] [10] [11] Bacillus species are also found in marine sponges. [11] Marine sponge associated Bacillus subtilis (strains WS1A and YBS29) can synthesize several antimicrobial peptides.

  7. Bacillaceae - Wikipedia

    en.wikipedia.org/wiki/Bacillaceae

    The Bacillaceae are a family of gram-positive, heterotrophic, rod-shaped bacteria that may produce endospores. [1] Motile members of this family are characterized by peritrichous flagella. Some Bacillaceae are aerobic, while others are facultative or strict anaerobes. Most are not pathogenic, but Bacillus species are known to cause disease in ...

    Dialysis can be helpful in the short term but can do only 10% to 15% of what a healthy kidney does, and people on dialysis face a 50% chance of dying in five years after beginning the treatment ...

  9. Schaeffer–Fulton stain - Wikipedia

    en.wikipedia.org/wiki/Schaeffer–Fulton_stain

    A stained preparation of Bacillus subtilis showing endospores as green and the vegetative cell as red. The Schaeffer–Fulton stain is a technique designed to isolate endospores by staining any present endospores green, and any other bacterial bodies red. [1]
