Hello students.
00:01
Now in this question, they are asking what or rather which of these organisms can contaminate a container of orange juice? is it the neutrophils, the thermophile, the acidophile, obligate anaerope or the mesophy? now, if we observe in the case of orange juice, they have given that ph is equal to 3.
00:23
What does ph equal to 3 mean? it means that the environment is acidic, correct? so in this case, it definitely can't be neutrophil.
00:33
Why is it not neutrophil? because neutrophil is a white blood cell, correct? it is present in alkaline environment in the blood, right? so it is definitely not the first option.
00:47
Coming to the second option, they have given that it could be a thermophile which can contaminate this or in juice container.
00:55
In this case, thermophile is basically the organism.
00:59
The bacteria that can grow at high temperatures, right? you can observe them to grow at high temperatures.
01:08
What about acidophiles? now, these are the ones that can grow at ph less than five.
01:15
And extreme acidophiles can grow at ph less than or equal to two even.
01:22
Right.
01:23
And in case of obligate anaerope, what you'll observe? you will observe that in even the, slightest amount of oxygen, they will not survive...
