Bacillus cereus, Clostridium tetani
When growing conditions are not right, many bacteria form
No, Staphylococcus epidermidis is not an endospore-forming bacteria. Endospores are a survival mechanism produced by certain bacterial species, such as Bacillus and Clostridium, but not by Staphylococcus epidermidis.
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.
Heating a soil sample to 80 degrees Celsius for 15 minutes primarily targets endospores, as these structures are highly resistant to heat. This process can effectively kill most vegetative cells while allowing endospores to survive and remain viable. However, it does not specifically isolate endospore formers, as the heat treatment does not differentiate between endospore-forming and non-endospore-forming bacteria. Thus, the heating primarily isolates endospores while not necessarily isolating the organisms that produce them.
Pili or fimbriae are hair-like appendages on the surface of some bacteria that help them attach to surfaces. These structures provide the bacteria with the ability to adhere to various materials, forming biofilms that can be difficult to remove.

Some bacteria respond to an unfavorable environment by forming endospore.

Acid fast Mycobacterium have a waxy molecule in their cell wall that will take up and retain the malachite green stain when subjected to the endospore staining process. The uniformly green appearance of endospore stained acid fast cells doesn't mean they produce endospores. These are vegetative cells that have taken up color from the heat driving malachite green into their waxy cell wall.
a bacterial cell will form (essentially morph into) an endospore when its environment changes. If the cell has adapted to survive in warm, moist conditions with an abundance of proteins and then if these conditions the bacterial cell has adapted to are changed, conditions aren't warm or moist then as a survival mechanism it will essentially morph into an endospore. Then when conditions change back to the cells original ideal conditions, tiny chemoreceptors on the endospore will activate genes in the cell to morph back into its normal form.

No, E. coli does not form endospores. Endospores are a dormant, resistant form of some bacterial species, like those in the Bacillus and Clostridium genera, which allow them to survive harsh conditions. E. coli is a gram-negative bacterium that does not have the ability to form endospores.
Found this answer on examville.com, when I was searching the net for my homework assignment.Milk supports the growth of a variety of bacteria including pathogenic one The different types of bacteria present in milk are, as follows: 1. Acid-fonning bacteria, such as Streptococcus lactis Str. faecalis Lactobacilli These ferment lactose, forming lactic acid, and lead to the formation of curd. 2. Alkali-fonning bacteria, such as Alkaligenes sp. Achromobacter Aerobic spore-forming bacilli These render the milk alkaline. 3. Gas-forming bacteria, such as Coliform bacteria Cl. peifringens Cl. butyricum These produce acid and gas. 4. Proteolytic bacteria, such as Bacillus subtilis B. cereus Proteus vulgaris Staphylococci Micrococci These bacteria are responsible for proteolytic activity. 5. Inert bacteria, such as Achromobacter Pathogenic bacteria Cocci They do not produce any visible change.

Sporulation is the process for bacteria that results in the production of an endospore. When bacteria are in a hostile environment, they produces dormant bodies known as endospores. Sporulation enables the bacteria to survive in hostile environments until a more suitable environment is available.
