Hello everyone.
00:04
Here in this question, there is a table which shows fermentation of sugars by three bacteria.
00:09
And we have to check these bacteria if they are capable of fermenting the three sugars.
00:17
Okay.
00:18
So this is the fermentation test basically which helps to differentiate between the different bacterial species based on the ability to ferment particular sugars.
00:28
Okay.
00:29
So the three sugars which are there in the first test tube, is glucose.
00:34
In the second test tube, it is the lactose sugar.
00:37
And in the third test tube, it is the manadol sugar.
00:41
Okay.
00:42
Now, the organisms which are there, the first one is the e.
00:46
Coli.
00:48
Okay? so, first one is the ischerine coli.
00:53
Okay, the second bacteria is the pseudomonas, erogenosa and the last one is basilis subtlis okay now the fermentation test it is used to determine whether or not the bacteria can ferment a specific carbohydrate okay so when we perform this test e.
01:29
Coli, it is able to ferment the glucose.
01:35
So, the e.
01:36
Coli gives this test positive with the color yellow in the test tube and with the production of gas...
