Humans also long ago discovered-without understanding why-that these invisible little life-forms could do them good service. For instance, the Chinese used fermentation by fungi to make vinegar, monosodium glutamate and soya sauce, and red yeast to make food dye and honglujiu, a red rice wine. Pharmacopeias of traditional Chinese medicine include over a dozen fungi.
人類也在不明究裡下早役使這些隱形小生命為自己服務，比如中國人用真菌發酵製造醋、味精、醬油，用紅麴染色、製造紅露酒。
