Abstract: The present disclosure provides methods for producing acetaldehyde from renewable biological resources, for example, from a fermentable substrate, with the advantages of energy efficiency and ease of purification. Particular embodiments, feature the production of acetaldehyde from pyruvate, wherein the pyruvate is generated from various carbon sources (e.g., sugars) by pyruvate-producing microorganisms. The methods comprise culturing a pyruvate-producing microorganism in a culture medium under conditions such that pyruvate is excreted and accumulates extracellularly, resulting in a pyruvate-enriched medium.
