  • Which microorganisms are used in bioremediation of wastewater?
  • Microalgae including eukaryotic algae and cyanobacteria are photosynthetic microorganisms and serve as promising agents for bioremediation (biological treatment) of wastewater . They are the sustainable and eco-friendly approach for the removal of nutrients, heavy metals, and other organic pollutants in municipal and industrial wastewater .
  • What factors influence the bioremediation process or biodegradation of influent wastewater?
  • The following factors influence the bioremediation process or biodegradation of influent wastewater like toxicity and stereochemistry of compounds, its concentration, retention duration, degradation circumstances, the presence and concentration of additional chemicals, and the effectiveness of chosen microbial stain (Misal et al., 2011).
  • Is bioremediation a viable alternative to traditional wastewater treatment plants?
  • The use of bioremediation as an environmentally benign method for the decontamination of harmful contaminants for environmental sustainability and safety has gained popularity due to the several disadvantages (expensive, operation, efficiency, and start-up) of traditional wastewater treatment plants.
  • Is bioremediation a sustainable approach?
  • Over time, there has been extensive research and commercial optimization of suitable wastewater treatment strategies that can ensure reuse or safe environmental discharge. Bioremediation is regarded as a sustainable approach because it is relatively cheap and environmentally friendly.
