That's fascinating, the evolution of enzymes to shift the measure of what is stable over a given period of time. > Once you have white rot you can break down lignin, the major precursor of coal. I'm curious there how is it know that lignin is the precursor to coal. What is coal anyways, is there a molecular structure to it. Ha, what a cool hit for that search, a rock, who'd have thought. I never heard of a maceral before. > Coal is a sedimentary rock that is composed principally of two basic classes of materials: inorganic crystalline minerals and organic carbonaceous macerals. The macerals form the combustible part of the coal and are, in turn, divided into three maceral groups—vitrinite, exinite, and inertinite. https://www.sciencedirect.com/science/article/pii/B9780121507015500097 https://www.sciencedirect.com/science/article/pii/B978012150...
