the mold that ferments your soy sauce and occasionally invades your lungs, depending on its mood

means A common genus of molds (fungi) that produces fuzzy spore-bearing heads, used industrially to ferment foods like soy sauce, miso, and sake, but capable of causing serious lung infections in vulnerable people.

from Named in the 18th century by an Italian priest and biologist, Pier Antonio Micheli, who peered at the mold's spore-laden stalks under a microscope and was reminded of an aspergillum — the perforated holy-water sprinkler used to bless congregations. That word traces back to Latin 'aspergere,' to sprinkle or scatter (from 'ad-,' toward, plus 'spargere,' to strew). So the fungus is, quite literally, the 'little sprinkler' — a name born at the intersection of the laboratory and the altar.
