The Mycogenian microfarms are a location in Isaac Asimov's Foundation series.
Description[]
The Mycogenian microfarms are the advanced agricultural production facilities of the Mycogen district on Trantor. Located deep underground, the vast and sprawling microfarms are the source of Mycogen's wealth and the high-quality microfoods that are sold across the Galaxy and are rumored to be eaten exclusively by the Emperor himself. The farms are a marvel of bio-engineering, characterized by their impeccable cleanliness and lack of the foul odor typically associated with such facilities on other worlds. Mycogenian biotechnicians have developed perfect algal and saprophytic strains that grow under precisely controlled conditions: algae thrive under pure, pink-tinted light in carbon-dioxide-rich electrolytic solutions, while fungi are cultivated in dimmer, twilight sections. The entire process is highly automated and monitored by a small number of dedicated brothers and sisters who study indicators and adjust controls. Despite the automation, the brain and reasoning of Mycogenians are considered essential, and every member of the sect works in the farms at some point. The farms are a source of immense sector pride, embodying the Mycogenian ethos of self-reliance and technological mastery over nature.
It was during a tour of these farms that Raindrop Forty-Three revealed to Hari Seldon the existence of her people's most sacred artifact, the Book.
