Yeah. Like sour milk. Sauerkraut. Many bacteria emit acids as waste. Spoiled meat smells sour to me. Some day I will eat:
Surströmming.
It wouldn't surprise me if some bacteria emit bases, though.
Some fungi who are our friends produce the famously bitter alcohol.
And unripe fruits are frequently sour. Green apples. Green tomatoes.
