Microbial production of aromatic phenolic compounds is a burgeoning area of biotechnological research with immense potential in various industries. The use of microbial production methods for aromatic phenolic compounds offers several distinct advantages, aligning with the principles of sustainability, cost-effectiveness, product quality, scalability, and controllability. Microorganisms such as bacteria, yeast, and fungi have been engineered or selected for their ability to biosynthesize a spectrum of aromatic phenolic compounds through metabolic engineering, fermentation, or bioconversion processes. Various precursor molecules, such as sugars, lignin-derived substrates, and aromatic amino acids, serve as feedstocks for microbial conversion into an array of phenolic compounds, including phenolic acids, flavonoids, stilbenes, and lignans. Continued advancements in metabolic engineering, synthetic biology, and bioprocess optimization are poised to further enhance the yield, specificity, and cost-effectiveness of this biotechnological approach, thereby unlocking new opportunities for the commercialization of these valuable compounds. Further, the exploration will encompass the dynamic realm of strain improvement and yield enhancement, showcasing the pivotal role of genetic manipulation techniques, such as CRISPR-Cas9 and directed evolution. These techniques offer precision in optimizing microbial strains for enhanced productivity, thereby contributing to the economic viability of microbial production. The present chapter offers a comprehensive guide to researchers, industry professionals, and policymakers seeking to capitalize on the potential of microbial production of aromatic phenolic compounds for a sustainable and bioactive future.
