Tetragenococcus halophilus (a bacterium) and Zygosaccharomyces rouxii (a fungus) are two facultatively anaerobic species that thrive in moromi. Through fermentation, Tetragenococcus produces lactic acid (lactate in its ionized form) and Zygosaccharomyces produces ethanol. What molecule is transformed into these waste products? Describe the two processes. What other waste products are produced?
