Bacterial generation time is the time is takes for a bacteria to double in quantity. An example of slow growing would be Mycobacterium Tuberculosis (24 hours) and fast growing would be E. Coli (about 20 minutes).

What is bacterial culture?
A laboratory test. bacteria are identified by the appearance of their colonies, by.biochemical tests, and through a Gram stain. bacteria are tested against different antibiotics to determine which will treat the infection by killing the bacteria.
I am growing bacteria and there's this white fuzzy stuff on top of it. Is that bacteria too or is it something else?
It is bacteria! >:-D
What is broth culture?
The culture which contain an organism (bacterial colony) which you are required to grow in a broth media that is a media lacking solidifying agent agar. A pure culture should not contain other bacterial or fungal cells in it except the required or cultured one
Can you use blood to grow bacteria on petridishes?
Bacteria will grow in blood but no the growing medium in petri dishes should be clear agar.
Why are there areas on the agar jelly where no bacteria are growing?
There are areas on the agar plate where no bacteria grow because that area was missed when the plate was streaked.
What is the difference between bacterial cidal and bacterial static?
Bacterial cidal kills the bacteria, while bacterial static only stops it from growing and reproducing.
How are most bacterial infection get transmitted?
the bacteria comes in contact with nurturing, growing medium like mucus or saliva
Why is temperature control an effective weapons against bacterial growth?
Bacteria ideally needs a warm and wet climate to live and grow in. If it is cold and dry then the chance of bacteria growing is very little if at all.
What type of bacteria is most likely to go through fermentation?
Assume you are growing bacteria on a lipid medium that started at pH 7. The action of bacterial lipases should cause the pH of the medium to increase or decrease? Why?
Which statement best explains why no mold is growing in the white area next to the bacterial colony?
2. The bacteria may release a substance that prevents mold growth.
What is the bacteria growing in your tomato paste?
the bacteria growing in tomato paste is microbe
What is the cause for bacteria to grow?
The cause for bacterial growth depends on what the bacteria is growing upon. Usually the case may be having something stored at higher temperature when it should not be, or leaving food out that needed to be stored in a cooler. Bacteria live off dead and decomposing material, this is how they live and reproduce.
Why is it important to seal a container when growing bacteria?
A container that has growing bacteria must be closed and/or sealed to prevent contamination by other bacteria.
How do antiseptics work to kill bacteria?
You use them on your hands to kill bacteria. Examples are Hand sanitizers, or soap now how they work to kill them is another question, well they for example inactivate the bacteria remove them make the bacteria "blowup", and they can stop bacteria from growing.
What are the significance of bacterial growth curve in food preservation?
Well bacterial growth curve give simply the time vs no of cell curve which can be consider for different bacteria that at which temprature and pH they can stop growing, which would help in preserving food.
Why did bacteria in the agar dish turn yellow?
to see time fly! You may be referring a bacterial transformation experiment. If so, the bacteria turns color to indicate that the DNA that was transferred to the bacteria is being expressed and the transformation was successful. If you are referring to the natural color of bacteria growing in large colonies on agar, that beige color is their natural color only visible when they are growing in colonies by the millions. The yellow color could also be a fungus which has contaminated your plate which happens often in a non-sterile classroom environment. Never open a petri dish after bacterial growth or fungal growth is evident.
Does the stench produced by my agar plates mean bacteria is growing?
Yes bacterial colonies growing on agar plates tend to metabolize the medium leaving "fermented" waste products that are generally of foul odor. You should also be able to spot clusters of spots forming to confirm this hypothesis
