Microbial Remediation — Prelims Strategy
Prelims Strategy
For Prelims preparation, focus on memorizing specific microorganism names and their applications (Pseudomonas-hydrocarbons, Bacillus-versatile, Alcanivorax-marine oil). Create a matrix of pollutant types versus suitable microorganisms for quick recall.
Memorize key numerical data: cost savings (50-80%), treatment timelines (months to years), and efficiency percentages from major Indian projects. Practice distinguishing between bioaugmentation (adding microbes) and biostimulation (adding nutrients) - this confusion appears frequently in options.
Learn the regulatory framework basics: Environment Protection Act 1986, Water Act 1974, and recent amendments. Focus on current affairs integration, particularly NMCG initiatives and recent research breakthroughs.
Use elimination techniques by understanding that extreme conditions (very high/low pH, temperature) generally limit microbial activity. Remember that microbial remediation is slower but cheaper and more environmentally friendly than chemical alternatives.
Practice questions involving comparison tables and matching microorganisms with applications.
