Tag: Carbohydrate fermentation

According to the U.S. Energy Information Administration, most of the fuel ethanol produced around the world is made by fermenting the sugar found in plant starches. Yes, ethanol is made from carbohydrates, which serve as the primary feedstock for the fermentation process that yields this important biofuel.

The ability to ferment specific carbohydrates is a key characteristic used to classify and differentiate bacteria. Recognizing what does a positive carbohydrate fermentation test look like is a fundamental skill for microbiology students and laboratory technicians, relying on clear visual cues after incubation.
