P.), India In the modern time enzymatic works have achieved a sound attention due to their successful involvements in several types of tedious syntheses without generating any type of environmentally harmful pollutants. It has also been proved that laccases have such types of capabilities to perform several environmentally safe roles in food, paper-pulp, textile, cosmetics, nanotechnology, sugar industries, synthetic organic and drugs chemistry. In most cases, laccase mediator systems play very important roles and in such cases, reactions were difficult or impossible without mediators but the studies of yellow laccases and their capabilities to oxidize phenolic lignin model compounds without help of any mediator systems have good future with several possibilities in industrial and medicinal areas. In the above respects, this review represents the concise and compact comparative studies on blue and yellow laccases with their different important properties. http://pubs.sciepub.com/plant/1/2/5/plant-1-2-5.pdf blue laccase yellow laccase mediators lignin model compounds
