How you differentiate between Transformed bacterial colonies and satellite colonies?

Re-streak the center of the 'star' colony (transformed surrounded by satellites) on a plate contains the antibiotic, typically ampicillin. The colonies in the tertiary streak will most likely be the transformants. If you want to be quite sure, pick a single colony from the tertiary streak and re-streak again on a plate containing the antibiotic.

What was true about the American colonies after the Continental Congress met?
The American Revolution transformed thirteen British colonies into fourteen states.
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
How do you distinguish between bacterial colonies and yeast colonies?
Under a microscope a yesat should have long filamentous hyphae whereas bacteria are simple rods or cocci. Acidic or antibacterial mediums should kill most bacteria most fungi (including yeasts) will remain living.
What are colonies of bacteria?
Bacterial colonies are defined as the assamblage of bacteria growing on a solid surface such as the surface of an agar culture medium, the assemblage often is directly visible, but also may be seen only microscopically.
What are the Three regions of colonies?
the new England colonies, the middle colonies, and the southern colonies
Do yeast colonies resemble bacterial or fungal colonies?
bacterial
What is non selective media?
Non-selective is when we use agar for bacterial growth in general. Mean not to differentiate between them but just to see their colonies and growth. TSA and Chocolate agar are nonselective.
What does the phenotype of the transformed colonies tell you?
Nothing because I have no clue what you are talking about... Which colonies from what?
What color are satellite colonies?
white
Yeast colonies larger than bacterial colonies?
Not necessarily, some Bacillus can have big colonies
How were the colonies transformed into sovereign states?
(by forming their own governments)
Are satellite colonies sensitive to ampicillin?
Yes, satellite colonies may be observed radiating from the edges of large, well-established colonies. These satellite colonies are not ampicillin-resistant, but grow in an "antibiotic shadow", where ampicillin in the media has been broken down by the large resistant colony. Satellite colonies are generally a sign of antibiotic weakened by not cooling medium enough before adding antibiotic, long-term storage of more than 30 days, or overincubation.
How many bacterial colonies are in a guinea pig mouth?
a lot
Do all bacterial colonies consist of pure cultures?
YES.!!
How to determine Bacterial load?
By pour plate and then counting the colonies.
What was true about the American colonies after the Continental Congress met?
The American Revolution transformed thirteen British colonies into fourteen states.
Why would bacterial colonies found in the first section of a streak plate but not on sections two and three?
why could bacterial colonies found in the first section of a streak plate but not on sections two and three
