Pigment-producing microorganisms are widespread in nature, but transforming their potential from lab-scale studies to commercial applications has been a complex journey. Twenty-five years ago, researchers debated whether microbial pigments would remain scientific curiosities or evolve into viable industrial products. Today, the picture is mixed; some microbial processes, using fungi, bacteria, or yeasts, have achieved industrial-scale production of pigments like carotenoids and phycocyanin. However, commercialization involves several challenges. For instance, Monascus-derived red pigments are widely consumed in Asia, with over a billion consumers, yet remain banned in several other countries due to safety concerns. Broader acceptance, especially in Europe and North America, hinges on the development and global availability of strains proven to be toxin-free, such as those genetically engineered to delete citrinin-producing genes. Bringing new microbial pigments to market is resource-intensive. Each new pigment or microbial source demands extensive experimentation, process refinement, safety testing, and regulatory clearance. The future of pigments such as azaphilones or anthraquinones depends on the outcomes of ongoing investments. Emerging strategies include combinatorial biosynthesis, targeted gene deletions, and the microbial production of rare pigments, and these advances may shape the next generation of natural colorants.
