We've done a deep delve into the world of fungi in the past here on Cake, most notably these threads!
It definitely seems like the spores of fungi-based innovation are in the air! Check out this announcement via BoingBoing of a new type of pet food & treats based on Koji fungus:
Wild Earth is a dog food start-up in Berkeley, California. It specializes in dog food made from the Aspergillus oryzae fungus, known as koji in Japan. Koji is used to make "soy sauce and fermented bean paste (including miso), and also to saccharify rice, other grains, and potatoes in the making of alcoholic beverages such as sake and shōchū." [Wikipedia]. Chemical & Engineering News reports that Wild Earth recently secured $11 million in VC funding from "VegInvest, Mars Petcare, and other backers." This looks like a great snack for people, too.
Would you check out Wild Earth products? (Also, I love miso soup, so I had no idea it had a delicious and tasty fungus component!)
