Why is it important to start a bacterial culture with a single isolated colony?
It is important for someone who works with bacteria to have a genetically identical bacterial colony so they can test different things on one type of bacteria. Making observations on that one colony is valuable for visual research and identification of that microorganism.
Why colony represent a pure culture?
The colony started from one single microbe that divided and divided until it formed what we call a colony of all the same bacteria. By selecting that colony we can be sure that its is pure and will grow only into a pure culture. Be sure to select on that is isolated so that you will not pick up a contaminate.
How would you check the purity of an isolated colony that was picked off a streak plate?
Well, isn't that a happy little question! To check the purity of your isolated colony, you can simply pick a small amount of the colony and streak it onto a fresh agar plate. If only one type of colony grows on the new plate, then your original colony is likely pure. Just remember, there are no mistakes, only happy little accidents in science!
What is the minimum number of bacteria present on one of your plates?
The minimum number of bacteria present on a plate is 1. Depending on how well the bacterial colony was isolated, there may be different kinds of bacteria present.
What was the first virus to be isolated?
The first virus to be isolated and identified was the tobacco mosaic virus in 1892 by Russian scientist Dmitri Ivanovsky.
Which colony was isolated?
be more specific, which colony of which sample from what experiment?
Why would you assume that an isolated colony is a pure colony of that microorganism?
Because bacterial cells reproduce and form identical daughter cells. Therefore, a single cell that is isolated away from the rest of the mixed bacterial culture will reproduce a colony of cells identical to itself. You will know that it is only that certain type of bacteria with none others mixed in, or pure :)
Why can a single colony on a plate be used to start a culture?
The colony started from one single microbe that divided and divided until it formed what we call a colony of all the same bacteria. By selecting that colony we can be sure that its is pure and will grow only into a pure culture. Be sure to select on that is isolated so that you will not pick up a contaminate.
How an isolated colony forms?
Certain Isolation techniqiues are based on the concept that if an individual bacterial cell is separated from other cells and provided adequate space on a nutrient surface, it will grow into discrete mound of cells called a colony
How was the colonization of Asia different from the collars colonization of the New World what kind of European colony was established most in Asia?
How Asia was isolated at first then open to Europeans and became isolated once again what role did route religion play in this process
Is the urine colony count an appropriate indicator of the need for an antimicrobial susceptibility test of an organism isolated from urine cultures why?
water than more wayer

What factor contributes to the difference in the appearance of isolated versus crowded colonies?
1. The factors that contribute to the differences in appearance of isolated vs crowed colonies are: 1. Availability of nutrients, where colonies are crowed the bacteria will be in competition for nutrients and because of this there can be a reduction of size and shape also growth can also be stunted whereas in isolated colonies the nutrients is readily available with no competition for nutrients. 2. space, isolated colonies have more space to grow as compared to crowded colonies and 3. If there is contamination in a crowded colony the texture will be very difficult to determine however texture can be viewed in isolated colonies so contamination is a factor.
What is an adjective for the word isolated?
The adjective for "isolated" is "lonely" or "secluded."
