Endospore - Wikipedia
An endospore is a dormant, tough, and non-reproductive structure produced by some bacteria in the phylum Bacillota. [1] [2] The name "endospore" is suggestive of a spore or seed-like form (endo means 'within'), but it is not a true spore (i.e., not an offspring). It is a stripped-down, dormant form to which the bacterium can reduce itself.

4 天之前 · An endospore is a dormant, tough, and non-reproductive structure produced by certain bacteria from the Firmicute phylum. Endospore formation is usually triggered by lack of nutrients, and usually occurs in Gram-positive bacteria.
2.4E: Endospores - Biology LibreTexts
2023年8月31日 · Endospores are dormant alternate life forms produced by the genus Bacillus, the genus Clostridium, and a number other genera of bacteria, including Desulfotomaculum, Sporosarcina, Sporolactobacillus, Oscillospira, and Thermoactinomyces.
Endospores - Meaning, Structure, Stains and Formation Steps
Endospores, as the name suggests, are seed-like formations produced within the bacteria. They are highly resistant, designed to ensure survival and preserve the genetic information under environmental stress.

2023年1月30日 · 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 …
Bacterial Endospore - an overview | ScienceDirect Topics
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.

2021年5月28日 · Basically there are two types of bacterial spores: Endospore: It is produced within the bacterial cell. Bacteria like Bacillus, Clostridium, Sporosarcina, Thermoactinomyces produce endospores. Exospore: It is produced outside the cell. Very few bacteria produce exospores. E.g. Methylosinus; Structure and properties of Endospore:

2012年12月3日 · Sporulation in Bacillus subtilis involves an asymmetric cell division followed by differentiation into two cell types, the endospore and the mother cell. The endospore coat is a multilayered...
Endospore - an overview | ScienceDirect Topics
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).
