Proposed metabolic pathways related to acetaldehyde production from ethanol under aerobic (A) or anaerobic (B) conditions or from glucose under aerobic (C) or anaerobic (D) conditions. Solid arrowed lines, metabolic pathways common for Streptococcus and Neisseria strains (A,B) and Streptococcus strains (C,D); Dash arrowed lines, metabolic pathways specific to certain bacteria (see text). LDH, lactate dehydrogenase; PDH, pyruvate dehydrogenase; POD, pyruvate oxidase; PAT, phosphate acetyltransferase; AK, acetate kinase; Aldehyde DH, aldehyde dehydrogenase (acylating); Alcohol DH, alcohol dehydrogenase; NADH OD, NADH oxidase; PFL, pyruvate formate-lyase.
