With all the Doctor Who fanfare last month celebrating 50 years of the show it's notable that myco-protein science was part of the show back in the 70's.
In The Green Death, the quintessential Doctor Jon Pertwee shares a supper with a Welsh anarchist who has devised a way to weave mushroom protein into steak - 18 years before the first Linda McCartney sausage.
Mind you Quorn - the mycoprotein brand that retails in the shops, first appeared in 1985 as a product on shelves, but was created in the laboratory in the 1960's.
The filamentous fungus, or more precisely the mould, Fusarium venenatum, was discovered in 1967. It was already science fact, not science fiction back then.
