Answer 1

Bio-remediation is a technique that involves the use of organisms to break down environmental pollutants. Generally, fungi like yeast and bacteria are used for bio-remediation. A yeast, Yarrowia lipolytica is used to absorb the toxins released during the production of palm oil and the heavy metals and minerals released in some other industrial processes. Saccharomyces cerevisiae is used for absorption of a pollutant, arsenic. Oil spills in oceans are cleaned with the help of Alcanivorax bacteria.
