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).
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 ]
It has been proposed that endospore formation has allowed for the survival of some bacteria for hundreds of millions of years (e.g. in salt crystals) [14] [15] although these publications have been questioned. [16] [17] Endospore formation is limited to several genera of gram-positive bacteria such as Bacillus and Clostridium. It differs from ...
Fig1. 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.
The endospore is a dehydrated cell with thick walls and additional layers that form inside the cell membrane. ... Bacteria have developed several strategies to evade ...
Tiny plastic particles have been found throughout the human body, but researchers say they’re just starting to understand the impact. When Jaime Ross, PhD, a neuroscientist and assistant ...
Seed oils, including peanut oil and sunflower oil, have been in the news a lot recently. Dietitians explain if seed oils are healthy, and health risks of them.
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]
