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.

microbes use replication procedure for xenobiotic compound transformation. A xenobiotic is a chemical which is found in an organism but which is not normally produced or expected to be present in it. It can also cover substances which are present in much higher concentrations than are usual. Specifically, drugs such as antibiotics are xenobiotics in humans because the human body does not produce them itself, nor are they part of a normal diet. However, the term xenobiotics is very often used in the context of pollutants such as dioxins and polychlorinated biphenyls and their effect on the biota, because xenobiotics are understood as substances foreign to an entire biological system, i.e. artificial substances, which did not exist in nature before their synthesis by humans. ​
