Why Mold grow at low PH than yeast?

Mold tends to grow at lower pH levels compared to yeast because it is generally more acid-tolerant. Many molds, especially those in the genera Aspergillus and Penicillium, can thrive in acidic environments by utilizing organic acids and other substrates as food sources. Yeast, on the other hand, typically prefers a more neutral pH for optimal growth and fermentation. Thus, the different metabolic pathways and adaptations of molds allow them to flourish in more acidic conditions.
