Greetings, If you want more insight on bioremediation, there is a wealth of knowledge available on the US Composting Council open public forum. I would pose the question of the practicality of Phanerochaete chrysosporium to them. Especially knowledgeable is Dr. Rufus Chaney, one of the head researchers at the USDA and a world expert on all things related to composting and bioremediation. To post to their forum, you first have to register: http://mailman.cloudnet.com/mailman/listinfo/compost Although Phanerochaete chrysosporium is not a mushroom per se, I would also consult the fungus expert Paul Stamets who recently wrote the bioremediation book, "Mycelium Running: How Mushrooms Can Help Save The World", as he is most certainly aware of Phanerochaete chrysosporium. Here's his book: http://www.amazon.com/Mycelium-Running-Mushrooms-Help-World/dp/1580085792/ref=sr_1_1?ie=UTF8&s=books&qid=1248550056&sr=1-1 He also is the owner of Fungi Perfecti which sells everything relating to mushrooms, including spawn to grow your own shitakes, etc. which I have been doing for years, not for remediation but to eat, preferably sauteed in a little olive oil with garlic. Here's his site with contact info: http://www.fungi.com Regards, Lowell Prag ----------------- On Sat, July 25, 2009 2:04 pm, Larry Nooden wrote: These white rot fungi decompose the lignin (brownish) in wood leaving a white mostly cellulosic residue behind. Lignin is a polymer of aromatic rings bearing some resemblance to dioxin and some other (but not all) pollutants, and the enzymes that degrade lignin can also attack dioxin et al. I think the trick is to keep the fungi going in the polluted soil I do not know how well that is going.
