The sporulation process of Bacillus subtilis Bacillus subtilis is a rod-shaped, Gram-positive bacteria that is naturally found in soil and vegetation, and is known for its ability to form a small, tough, protective and metabolically dormant endospore .
Under conditions of starvation, especially the lack of carbon and nitrogen sources, a single endospore forms within some of the bacteria through a process called sporulation. [15] When a bacterium detects environmental conditions are becoming unfavourable it may start the process of endosporulation, which takes about eight hours.
Prior to the process of sporulation the cells might become motile by producing flagella, take up DNA from the environment, or produce antibiotics. [ 6 ] [ 7 ] These responses are viewed as attempts to seek out nutrients by seeking a more favourable environment, enabling the cell to make use of new beneficial genetic material or simply by ...
Bacterial spores are not part of a sexual cycle, but are resistant structures used for survival under unfavourable conditions. [4] Myxozoan spores release amoeboid infectious germs ("amoebulae") into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops ...
Sporogenesis is the production of spores in biology.The term is also used to refer to the process of reproduction via spores. Reproductive spores were found to be formed in eukaryotic organisms, such as plants, algae and fungi, during their normal reproductive life cycle.
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 ...
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]
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 ]
