So I was reading this for something completely not-related but thought of you guys. I might not understand/agree with the need to have fungal dominated soil but here is something that might help you get it. Cellulose applications. Two reasons... first and most obvious... The cellulose will feed fungi and increase their population. Second... the fungi eat the cellulose by breaking it down. They use enzymes classified as Glycoside hydrolase. Why does that matter? "Glycoside hydrolases... are extremely common enzymes with roles in nature including degradation of biomass such as cellulose and hemicellulose, [and] in anti-bacterial defense strategies (eg lysozyme)" http://en.wikipedia.org/wiki/Glycoside_hydrolase So not only do these enzymes break apart cellulose but they potentially have anti microbial properties as well. Apply cellulose (sawdust, etc) to feed the fungi and kill the bacteria at the same time. Pretty cool. Note: I have not confirmed that the type of Glycoside hydrolase used to break apart cellulose actually does have ant-microbial qualities. Just something to think about. I haven't read it (I have to focus on what I am studying) but here is a related wiki... http://en.wikipedia.org/wiki/Lysozyme Did you know most store bought Parmesan cheeses have cellulose added to them?
