Bacterial endospores are resistant to antibiotics, most disinfectants, and physical agents such as radiation, boiling, and drying. The impermeability of the spore coat is thought to be responsible for the endospore's resistance to chemicals.
23 Νοε 2024 · Examples of bacteria that can form endospores include Bacillus and Clostridium. The endospore consists of the bacterium’s DNA and part of its cytoplasm, surrounded by a very tough outer coating. Endospores can survive without nutrients.
Bacterial endospores are among the most resistant form of spores and can survive intense heat and desiccation. They are also known to have an intrinsic resistance to radiation and chemicals including some aldehydes and oxidizing biocides (Setlow, 2006).
As bacterial spores are formed within the parent cell, these are called endospores. When vegetative cells of certain bacteria such as Bacillus spp and Clostridium spp are subjected to environmental stresses such as nutrient deprivation, they produce metabolically inactive or dormant form-endospore.
Bacterial endospores are simplified forms of the bacteria, consisting of the DNA genome, some small amount of cytoplasm, and a specialized coating that confers resistance to heat, radiation, and other harsh external conditions.
30 Ιαν 2023 · Bacterial spores are the most dormant form of bacteria since they exhibit minimal metabolism, respiration, and reduced enzyme production. Typically, Gram-positive bacteria are best known for producing intracellular spores called endospores as a survival mechanism.
