Determine the population of bacteria based on the bacterial colonies?

Assume each colony started as a single bacteria in the original culture. Count the colonies you have and multiply up according to how diluted you made the culture and how much of the original culture you used.

How do colonies of bacteria grow?
Bacteria or any organism have basic requirement to survive grow and multiply i.e. is food and nutrition. Bacterial colonies arise when bacterial cell get sufficient amount of nutrient and favourable condition like optimum temprature and pH. These factor influence the multiplication of bacterial cells which leads in the formation of their colonies, this can be observed in laboratory by growing bacterial cells on nutrient agar medium and on incubate it in incubator at specific temp. the colonies on petriplates of nutrient agar shows distince morphology by different bactreial species.
What is a bacterial colony?
Isolated colonies of bacteria are the result of a single bacterium which has replicated many times and eventually formed a visable lump of genetically identical bacteria. The colony's shape, texture and colour can somtimes be helpful in identifying the species of bacteria. For example collonies of Serratia marrceccens are typically pink, moist looking, round and small on nutrient agar. I laymans terms isolated colonies are the single separated spots (normally semi-spherical like zits) on the plate after it has been incubated. If the bacteria are put on the plate too close together they will form a lawn which looks like the whole plate is covered evenly.
How do you know colonies are bacteria?
you can view the colony in microscope by simple staining or without staining and also they have some specific colonial characterstics which are different from fungal like fungal colonies are almost have thread like structures on their boundries but bacterial did not
How would a cluster of bacteria be called?
The large population of bacteria is called syndrome.
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.
How to determine Bacterial load?
By pour plate and then counting the colonies.
What are the transgenic bacteria?
Trangenic bacteria are bacterial colonies which are genetically modified by deleting or adding a particular gene sequence.
How would the formation of bacterial colonies be affected if bacterial cells did not contain pili?
Pili is important to colonial bacteria because it protects the surface of its cells. In addition, it allows the bacteria to adhere to other organisms.
Do yeast colonies resemble bacterial or fungal colonies?
bacterial
What is incubation used for in culturing?
When doctors are trying to determine what bacteria is causing an illness they sometime get a sample from the person and swab it on a shallow glass dish that contains a material the bacteria like and grow on. Once the bacteria has grown into colonies technicians look at them under a microscope to determine what the bacteria is. The process of growing the colonies of bacteria is called culturing
Why does yeast colonies never allow other bacterial colonies to grow around in any media?
The yeast colonies never allow other bacterial colonies to grow around any media because they don't want competition. The yeast colonies never allow other bacteria colonies to grow around any media because they eliminate competition.
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.
Do dimes have more bacteria than pennies?
Actually copper, nickel and silver help to inhibit bacterial growth, therefore coins are far less likely to carry numerous bacterial colonies.
In what ways do the macroscopic features of bacterial colonies differ from that of molds?
Bacteria looks more glossy, white or yellow Molds will have a fuzzy look to them

Does bacteria has something to do with fungi?
Rather fungus can do more with bacteria.Bacterial colonies can be spoiled by fungus.In fact all the antibiotics(which kill bacteria) are derived from fungus.At the same time some bacteria can co-exist with fungus producing secondary bacterial infections.
