A single-celled fungus that burps CO2 and alcohol, and civilization called it progress.
means A living colony of yeast cells kept alive and fed so it can be used over and over to ferment bread, beer, or wine.
from 'Yeast' traces back to Old English 'gist', from a Germanic root meaning 'to foam' or 'to boil' — the same ancient root (via Indo-European 'yes-') that gives us words related to seething and froth, because that's exactly what a bubbling ferment looks like. 'Culture' comes from Latin 'cultura', meaning cultivation or tending, from 'colere', to till or care for — originally about growing crops, later stretched to cover anything deliberately nurtured, including armies of microbes kept alive in a jar on your counter.
