Part D - Fermentation Pathway A student analzyed a bacteria in lab and found that the bacteria produced acid and gas but no alcohol during fermentation. Use the fermentation chart to help you answer this question.

Pathway 4 - Propionic fermentation

Pathway 6 - Butyric-Butylic fermentation

Pathway 5 - Butanediol fermentation

Pathway 1 - Lactic Acid fermentation

Pathway 2 - Alcoholic fermentation

FERMENTATION PATHWAYS 1.
