Question

Which of the following are examples of bioaugmentation? An old uranium mine is being restored to be a park by adding cyanobacteria that remove uranium from the environment. "A field that was exhaustively used for growing soybeans is lacking in Nitrogen and can no longer support additional crops. Scientists add lupine plants to the field, as they have root mutualists that fix Nitrogen into the soil. " "A large crude oil spill has contaminated 2,000 hectares of land. Biologists introduce fungi to the location as they will absorb the harmful components of the petroleum." Pond microorganisms are added to a eutrophic lake to restore oxygen levels in the water. Pond microorganisms are added to a eutrophic lake to remove excess Nitrogen from the water.

0:00 Hello, students.

00:01 Now, in this question, they have asked regarding bio augmentation, which of the following examples are best suited for the process known as bio augmentation? first of all, what is this bio augmentation? in the case of bio augmentation, what we basically observe is that we augment a biological area or the nature as a result of which there is removal of contaminants.

00:27 What do we do we basically add certain useful microorganisms to a contaminated area right once we add that particular microorganism what happens there is removal of that contaminant right what is happening the removal of contaminant is what is happening so that is what we are going to observe in this case now, if we observe the first example they have given, they have given regarding the old uranium mine.

01:01 There is this old uranium mine.

01:03 What they do, they add cyanobacteria.

01:05 When they add cyanobacteria, what happens? that place wherein there's a lot of uranium present that is being removed.

01:13 Now, is this an example of biogmentation? yes, it is, right? coming to the second one.

01:19 They have given that in a field, there is, there were growing, soy beans.

01:26 Now, as a result of growing too much of soyabins, what has happened? there is decrease in the content of nitrogen levels.

01:35 Now what they do? they plant lupine, right? they add lupine plants.

01:40 When they plant this lupine, what happens is that they have root mutualist, as a result of which the nitrogen is fixed into the soil.

01:49 As a result, the nitrogen is coming back to its level...
