  2. 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 ...

    Bacterial growth curve\Kinetic Curve. In autecological studies, the growth of bacteria (or other microorganisms, as protozoa, microalgae or yeasts) in batch culture can be modeled with four different phases: lag phase (A), log phase or exponential phase (B), stationary phase (C), and death phase (D).

  4. Quorum sensing - Wikipedia

    en.wikipedia.org/wiki/Quorum_sensing

    Bacteria use quorum sensing to regulate certain phenotype expressions, which in turn, coordinate their behaviors. Some common phenotypes include biofilm formation, virulence factor expression, and motility. Certain bacteria are able to use quorum sensing to regulate bioluminescence, nitrogen fixation and sporulation. [12]

  5. Germination - Wikipedia

    en.wikipedia.org/wiki/Germination

    Germination is the process by which an organism grows from a seed or spore. The term is applied to the sprouting of a seedling from a seed of an angiosperm or gymnosperm, the growth of a sporeling from a spore, such as the spores of fungi, ferns, bacteria, and the growth of the pollen tube from the pollen grain of a seed plant.

    en.wikipedia.org/wiki/Heyndrickxia_coagulans

    H. coagulans is a Gram-positive, catalase-positive, spore-forming, motile, facultative anaerobe rod that measures approximately 0.9 μm by 3.0 μm to 5.0 μm. It may appear Gram negative when entering the stationary phase of growth. The optimum temperature for growth is 50 °C (122 °F); the range of temperatures tolerated is 30–55 °C (86 ...

    en.wikipedia.org/wiki/Clostridioides_difficile

    [4] [5] It is known also as C. difficile, or C. diff (/ s iː d ɪ f /), and is a Gram-positive species of spore-forming bacteria. [6] Clostridioides spp. are anaerobic, motile bacteria, ubiquitous in nature and especially prevalent in soil. Its vegetative cells are rod-shaped, pleomorphic, and occur in pairs or short chains. Under the ...

    en.wikipedia.org/wiki/Bacillus_subtilis

    Bacillus subtilis (/ b ə ˈ s ɪ l. ə s s u b ˈ t iː. l i s /), [3] [4] known also as the hay bacillus or grass bacillus, is a gram-positive, catalase-positive bacterium, found in soil and the gastrointestinal tract of ruminants, humans and marine sponges.

  9. Myxococcus xanthus - Wikipedia

    en.wikipedia.org/wiki/Myxococcus_xanthus

    This process, known as chemically induced sporulation, is triggered by the presence of glycerol and other chemical compounds at high concentrations. [35] The biological implications of this sporulation process have been controversial for decades due to the unlikeliness of finding such high concentrations of chemical inducers in their natural ...
