In micro-organisms such as yeast, a uni-cellular (or single cell) fungi, the process of anaerobic respiration is called fermentation. Ethanol, a type of alcohol, and carbon dioxide are produced ...

Culture broth pH was well maintained at 5.0. We cultured yeast in an aerobic fermentation and then switched to an anaerobic process to induce ethanol production, demonstrating how versatile the ...
