Hi, in the question different types of media which are used for growing bacteria are given and we need to match it with their appropriate description.
00:13
So the first one is the assay medium which is used for measuring the property which is exhibited by microorganisms.
00:24
For example, assay medium is the muller intent agar which is used for measuring the antipurton agar which is used for measuring the antipurton.
00:31
Sensitivity of a particular microorganism.
00:36
So, antibiotic discs are placed on the lawn culture of the bacteria on the mha agar and it is incubated and if you observe the growth the next day you can see the zone of inhibition which is formed around the discs that contain the antibiotic.
01:03
So measuring the zone of inhibition that is measuring the diameter of the zone of inhibition will give you the effectiveness of the antibiotic over the organism or the sensitivity of the organism towards the antibiotic.
01:20
So the mha agar can be treated as an assay medium.
01:27
The second one is the enriched media which contains certain organic substances which helps the growth of certain microorganisms.
01:39
For example, blood is added to enrich the medium in case of blood agar where it supports the growth of certain organisms.
01:49
You can check for the production of hemolyzing by the microbes in the blood agar.
01:58
So, blood agar is an example of an entrenched medium.
02:03
In case of selective medium, the medium selects or favours the growth of one particular organism over the other...
