Explanation / Answer

Bioremediation is a process of treating contaminated media by changing conditions and letting growth of micro organisms and degrade the pollutant.

2)purpose of bioremediation:

-it is a waste management technique.

-to degrade hydrocarbon value present in soil and make it fertile.

-to decrease the solid waste that has been increased widely by urbanisation,examples like plastic,hospital waste..

-there are many types of bioremediation processes like biosparging,bioventing,bioaugmentation, etc.. which allow microbes to grow and degrade them by different approaches.

3)

-IT is eco friendly and cost effective to that of incineration in clearing pollutants.

-IT is carried out in-situ(in labs) with no danger of spreading,transport etc..

-in lanfills that overfill,methanne gas is overproduced but can be contolled by air stripping, a process of bioremediation.

- minimal equipment needed.

4) anaerobic organisms:these are microbes that doesn't require oxygen for growth instead they survive on other compounds like methane etc..

Two types of anaerobes

i)facultative anaerobes

ii)obligate anaerobes

Example:propionibacterium,actinomyces,clostridium etc.

Aerobi organism: it is a organism that require oxygen for it's growth and development.

Oxygen is compulsory for it's growth in obligate aerobes.

Example:mycobacterium, pesdomonas aerogenisoa etc..

Facultative anaerobes: Eschericia coli, staphylococcus aureus..
