and an energy source (carbon). Bioremediation utilizes microbes such as bacteria, fungi, yeast, and algae that can biodegrade organic chemicals Biostimulation is the addition of nutrients to enhance the growth of native microbes. Microbes bioremediate the environment as they biodegrade the pollutant to obtain energy. Non/difficult to handle.
