So the question here is asking if the goal of serial dilution and the crowded plate technique is to separate the micro so we can count their colony forming units, the answer is a true or is a false.
00:13
The answer is false.
00:15
So with the serial dilution, you basically have, say, our sample.
00:25
Our sample is then, as the name states, serially diluted.
00:32
Okay, so we take a bit of the sample into the first tube.
00:39
Mix that up, then go to the next tube, and so on, and so on, and so on.
00:46
And each of these gets put on a plate to see how many bacteria have.
00:53
And we should see, we should see less bacteria the further down we serial dilute.
01:06
Okay, so that's serial dilution.
01:09
And yes, in this case, in serial dilution, we are getting, we're trying to decrease the number of bacteria to get smaller numbers of colony form units so that we can actually calculate and count how many bacteria is there.
01:28
But that's not the case with the crowdplating technique.
01:31
The crowd plating technique is typically used with soil and screening for soil...
