Why are agar plates dried before being used for the preparation of dilution streak plates?
perhaps it is easier to streak that way, i mean when the agar is set and dry. .
What does msa plates test for?
Shows if bacteria can tolerate salty conditions. If so, it will grow, if not, no growth will occur.
Where should colonies appear in the case of streak plates?
When using streak plates, the colonies should appear along the streak lines. This is where the bacteria have been introduced and is the first place they will grow.
Why it is said that number of theoretical plates should be high for a good efficiency?
In liquid chromatography the 'theoretical plates' number is a measure of the resolution between the peaks of different eluting substances. The higher the plate value the greater the separation. This is particular important as the load reaches the maximum the column is designed for.
What advantage does the streak plate method have over the pour plate method?
A disadvantage of the streak plate technique could be colony isolation problems. If the streaking technique is not done properly or if there is too much of an organism present on the inoculating loop then the cells can cluster and form what looks like one colony but it can actually be a couple colonies (made from a couple cells). This can cause an inaccurate colony forming unit count.
What is the purpose of inoculating tsa plates with samples from the zone of inhibition?
Any bacteria that grow in the zone of inhibition are resistant to the antibacterial used. By inoculating new plates with the bacteria, you will have a pure culture of resistant bacteria.
What are some classic number plates?
Some classic number plates are hand painted number plates, cast aluminum number plates, pressed aluminum number plates, and ACE digit number plates. These can be purchased at a shop called Framptons.
Why must we use sterile techniques to incubate agar plates?
Because if the plates are wet you will not get individual colonies, instead you will get a film of bacteria growing in the water film on the surface of the plate. This can ruin a selection for transformants as the antibiotic will not be present in the water film on the surface of the plate.
Why are number plates called number plates if they have letters in them?
We call them license plates where I live.
The strain of bacteria that caused pneumonia grew into what colonies on culture plates?
The disease-causing strain of bacteria grew into smooth colonies on culture plates, whereas the harmless strain produced with rough edges.
Are cartilaginous plates present in the bornchiole?
No, they are absent from the bronchioles.
Why is it important to kill all the bacteria in the raw sewage duringphage isolation?
because bacteia that are present will contaminate the plates that will be used to isolate phages and will be imposible to detect the phages.Normally sewage are filter sterilized before isolation.
how can i find someone by the license plates number?
how can i find someone by the license plates number
Can streak or spread plates isolate pure cultures from mixed bacteria?
YES
Did lactobacillus grow on mannitol salt agar?
Yes. M. smegmatis is a gram + bacteria, and MSA plates select for gram + bacteria.
What does 'cherished number plate' mean?
Prior to 1963, plates on vehicles were less governed resulting in plates issued that didn't expire, these types of plates are what are considered to be 'cherished number plates'.
What is the strian of bacteria that caused pneumonia grew into what colonies on culture plates?
good question!
