Answer 1

1 the action of remedying something, in particular of reversing or stopping environmental damage 2Microbial bioremediation uses microorganisms to break down contaminants by using them as a food source. Phytoremediation uses plants to bind, extract, and clean up pollutants such as pesticides, petroleum hydrocarbons, metals, and chlorinated solvents.3 Organic pollutants hydrocarbons and chlorinated compounds are mostly removed by degradation, rhizoremediation, stabilization and volatilization, with mineralization being possible when some plants such as willow and alfalfa are used

4 Pseudomonas aeruginosa, an organism ubiquitous in nature, has assumed an increasingly prominent role as the aetiological agent in serious infections in hospitalized patients. Pseudomonas has a number of pathogenic properties, which include its capsule, exotoxin A and various proteases.

5 Anand Chakraborty, a scientist of Indian origin, has worked on Pseudomonas aeruginsa which have reduced the crude oil films into carbon dioxide and water. Why Dr. Anand Chakarborty's work phenomenal? ... This helps in controlling the oil pollution of marine waters which otherwise is very difficlt to control.
