What is a spore forming group of organisms?
Spore formers are a group of bacteria which form an endospore. When certain bacteria are stressed, sub-lethally injured, or placed in danger in any way it will form what is know as an endospore. The endospore contains all of the necessary genetic information necessary to regenerate a new vegetative bacterial cell if the bacterium is killed or lethally injured. Endospores will not germinate into vegetative cells unless the original bacterium is killed and the threat has subsided.
What do endospores do for bacteria?
It allows the bacteria to create a resistant and dormant cell that can preserve the original cells genetic material when put under extremely unfavourable conditions
What is the arrangement of a endospore?
position in which the endospore is found within the cell for example could either be terminal or central etc.
Does an endospore release toxins?
Yes
How is a endospore form?
When a bacterium detects environmental conditions are becoming unfavourable it may start the process of endosporulation, which takes about eight hours. The DNA is replicated and a membrane wall known as a spore septum begins to form between it and the rest of the cell. The plasma membrane of the cell surrounds this wall and pinches off to leave a double membrane around the DNA, and the developing structure is now known as a forespore. Calcium dipicolinate is incorporated into the forespore during this time. Next the peptidoglycan cortex forms between the two layers and the bacterium adds a spore coat to the outside of the forespore. Sporulation is now complete, and the mature endospore will be released when the surrounding vegetative cell is degraded.
What happens to the parts of the bacterium that are not protected by an endospore?
chicken
How is an endospore formed?
The bacterium copies it's chromosomes and produces a wall around the copy.
Does the bacteria tetanus need a host to survive?
No. The bacterium Clostridium tetani forms an endospore and can survive for long periods of time. When the endospore is introduced into a favorable environment it begins to metabolize.
Of what use is the endospore stain?
The use of endospore stain is to see specialized cell structures. It can tell if some bacterium cells contain higher resistant spores within vegetative cells.

Does e.coli contain a endospore?
E. coli is a motile, non-spore-forming, Gram negative bacillus.

Type of spore that can remain dormant until favorable conditions for growth arise?
A type of spore that can remain dominant until favorable conditions for growth arise is called an endospore. It refers to an asexual spore that develops inside some bacterial cells.
Why discovery of endospore was important in microbilogy?
the discovery of endospore allow the scientist to set a best temperature for stelization, and it have alerted them in the synthesis of different medicine, to what kind of medicine can pernatrate the endospore of a specific microorganism
What is the Dorner endospore stain?
you
Why is it important to determaine the location of the endospore?
Bcause the position of the endospore differs among bacterial species and is useful in identification.
