When this type of fungus grows on sugars like sucrose or glucose, its natural defenses (which help it handle stress) get weaker compared to when it grows on a protein-based food like peptone.

Similar Assertions

When this mold eats certain sugars like sucrose, glucose, or arabinose, it turns on genes that help make a toxin, and two of those genes become over three times more active than when it's eating something else.
