Microbiology Miscellaneous

  1. A bioremedial solution to reduce oxides of nitrogen and carbon in flue gases is to integrate flue gas emission to ​​
    1. micro-algal culture
    2. fish culture ​​
    3. mushroom culture ​​
    4. sericulture
Correct Option: A

The advantages of using a microalgal-based system in integration with flue gas emission are that :
⚈ High purity CO2 gas is not required for algal culture. Flue gas containing varying amounts of CO2 can be fed directly to the microalgal culture. This will simplify CO2 separation from flue gas significantly. ​​
⚈ ​Some combustion products such as NOx or SOx can be effectively used as nutrients for microalgae. This could simplify flue gas scrubbing for the combustion system. ​​
⚈ ​Microalgae culturing may yield high value commercial products. Sale of these high value products can offset the capital and the operation costs of the process. ​​
⚈ ​The envisioned process is a renewable cycle with minimal negative impacts on environment.
