The Mycological Chapter


For the last year and a half I have been living in the Pacific Northwest studying an array of sciences with an end all focus on mycology. After years of not staying in one place longer than a week or two, I have found myself a sweet little home in Olympia, Washington; with a dog (Rumi), a cat (Gouda), periwinkle trim, and a wood burning stove (Lucy). I moved to the temperate rain forest to dive into the study of mushrooms and the wonders that lie in the science that they participate in. This spring quarter at Evergreen State College I am doing a mycology contract, an independent study based learning, to focus fully on mycological based science and community. A portion of this contract has been dedicated to keeping record of Scientific journal articles that are particularly inspiring, mushroom media and technology, community based mycology events and documentation of my own forays in the surrounding areas in search of fruit-bodies (mushrooms).

The opening of this chapter is dedicated to my home land, the Napa Valley in California. Upon searching different data based for scientific journals primarily pertaining to medicinal mushrooms and myco-remediation (using mycelium to clean up toxic waste) I stumbled upon a journal about "Recycling of Vineyard and Winery Wastes as Nutritive Composts for Edible Mushroom Cultivation" written by Marian Petrea and Alexandru Teodorescua from the University of Pitesti, Faculty of Sciences, Romania. Having grown up in a Valley of copious wine production, squashing grapes with my feet in a barrel as a little girl and touching the "agricultural waste" every year after harvest, this article hits close to home.

Here's a taste taken directly from the article:
"Abstract. Every year, in Romania huge amounts of wine and vine wastes cause serious environmental damages in vineyards as well as nearby winery factories, for instance, by their burning on the soil surface or their incorporation inside soil matrix. The optimal and efficient way to solve these problems is to recycle these biomass wastes as main ingredients in nutritive composts preparation that could be used for edible mushrooms cultivation. In this respect, the main aim of this work was to establish the best biotechnology of winery and vine wastes recycling by using them as appropriate growth substrata for edible and medicinal mushrooms. According to this purpose, two mushroom species of Basidiomycetes, namely Lentinula edodes as well as Pleurotus ostreatus were used as pure mushroom cultures in experiments. The experiments of inoculum preparation were set up under the following conditions: constant temperature, 23°C; agitation speed, 90-120 rev min -1; pH level, 5.0–6.0. All mycelia mushroom cultures were incubated for 120–168 h. In the next stage of experiments, the culture composts for mushroom growing were prepared from the lignocellulose wastes as vine cuttings and marc of grapes in order to be used as substrata in mycelia development and fruit body formation. The tested culture variants were monitored continuously to keep constant the temperature during the incubation as well as air humidity, air pressure and a balanced ratio of the molecular oxygen and carbon dioxide. In every mushroom culture cycle all the physical and chemical parameters that could influence the mycelia growing as well as fruit body formation of L. edodes and P. ostreatus were compared to the same fungal cultures that were grown on poplar logs used as control samples."

Mycelium made car parts and styrofoam alternative!




There are more emerging eco-tech products incorporating mycelium as an alternative to an array of caustic chemicals globally. This is a company based out of Green Island, New York that caught the news and subsequently my eye, called 'Ecoactive' that is widely implementing mycelial inoculated agricultural waste of many types (corn husks, cotton hulls, etc.) as an alternative to Styrofoam packing materials. They are providing a fully compostable waste based product as an alternative to one of the most toxic (in production and disposal) products on the mass market, and they are doing it effectively!
They gained notoriety through the popularity of their greensulate product (a highly effective home insulation product made from mycelium) and the products as well as popularity have grown from there. You can read about that product on their website (listed below) as well as in popular science.
A recent contract with Ford has Gavin McIntyre and Eben Bayer, the founders of Ecoactive, experimenting using the same technology (mycelial inoculated agricultural waste) as car parts. Door paneling and dashboards for now, perhaps fuel in the near future (another research topic underway coming out of the amazon by a completely different research crew examining the hydrocarbons of a specific ecto-mycorhizal fungus).

Below I have pasted links to the Eco active web-page as well as a ted talk about the Styrofoam alternative and the CNN article about Ecoactive's work with Ford.

Amazing!
