The Many Uses of Myrothecium verrucaria

Myrothecium verrucaria is a common Deuteromycete found all around the world and is quite the potent cellulose decomposer and potential plant pathogen.

Because of that ability it has been tested by the United States Department of Agriculture to control invasive weeds such as kudzu. It is very fast acting, seeing degradation of health in the kudzu vine within twelve hours of application.
M. verrucaria also capable of killing specific plant parasitic forms of nematode, without harming the roots they infest or the free living nematodes in the area.
So this little Deutero-dude can be used as an herbicide, simultaneously it can be used to protect plants from parasitic worms. Talk about flexible! 
Oh, but it appears there is more that this little fella can do. A recent study published in PLoS ) One describes a novel "white" laccase (A form of the laccase with a max spectral absorption of 600nm) produced by M. verrucaria that is capable of decolorizing a wide range of dyes.

 In this study, the team of Dan Zhao, Xi Zhang, Daizong Cui, and Min Zhao isolated a unique form of laccase that when purified was capable of rapidly (In four out of the twelve dyes tested it only took 10 minutes!) removing the dye pigment.
Laccases are actually already used to decolor dyes in several textile processes, and the wide range of dyes that the particular form produced by M. verrucaria leads to yet another potential area that this fungus is capable of useful application. 
So we now a single species capable of being a , pesticide, herbicide, and dye remover(dyeicide?).  Oh and laccases such as the ones produced by M. verrucaria are also used as preservatives in drinks such as beer and juice. I am starting think the uses may in fact be unlimited.
Oh, and less you think this Fungus is all friendly, remember the cellulose decomposing capabilities I mentioned? It doesnt, mind using those skills to break down cotton...

So there you have it, one species, capable of giving us so much and at the same time taking the very shirt off our backs.
