Bioremediation — Prelims Strategy
Prelims Strategy
For Prelims, focus on factual clarity and conceptual distinctions. Master the definitions of key terms like biostimulation, bioaugmentation, phytoremediation, and rhizoremediation. Understand the classification of techniques (in-situ vs.
ex-situ, aerobic vs. anaerobic) with specific examples for each. Memorize the names of prominent microorganisms used (e.g., *Pseudomonas* for hydrocarbons, white-rot fungi for recalcitrants) and their primary roles.
Pay attention to the environmental factors influencing bioremediation rates (pH, temperature, nutrients, oxygen). Be aware of the major applications (oil spills, heavy metals, pesticides, waste treatment) and landmark case studies like Exxon Valdez.
Crucially, link bioremediation to relevant constitutional articles (48A, 51A(g)) and key environmental acts (EPA 1986) and principles (Polluter Pays). Practice MCQs that test conceptual understanding, factual recall, and the ability to differentiate between similar terms.
Focus on the 'what, where, when, and who' aspects of the topic.
