摘要

Psilocybin, a tryptamine-derived alkaloid from Psilocybe mushrooms, has emerged as a high-value biopharmaceutical candidate due to its promising applications in mental health. While clinical studies highlight its rapid and sustained antidepressant effects, current challenges lie in achieving scalable, reproducible, and cost-effective production to meet growing research and therapeutic demand. Traditional extraction from fungal biomass yields low concentrations and requires extensive downstream processing, limiting industrial viability. Chemical synthesis ensures purity but is hindered by high costs and multistep complexity. In contrast, biotechnological approaches have demonstrated significant progress toward sustainable production. Heterologous expression of psilocybin biosynthetic genes in Saccharomyces cerevisiae and Aspergillus nidulans has enabled improved metabolic flux and precursor availability, reaching titers over 200 mg/L under optimized conditions. Moreover, recent engineering Escherichia coli strains has further enhanced catalytic efficiency of key enzymes such as PsiH, achieving production levels up to 2000 mg/L, while simplifying fermentation and purification workflows. These advances establish microbial platforms as a promising route for industrial-scale biosynthesis. Beyond production, psilocybin offers an opportunity to integrate biotechnology with socio-cultural context. In regions where diversity of Psilocybe species and ancestral knowledge converge, the development of biotechnological pipelines could foster innovation in drug discovery, sustainable manufacturing, and policy reform. Overall, psilocybin exemplifies a frontier molecule in biotechnology, where metabolic engineering, synthetic biology, and bioresource valorization converge to transform a natural product into a reproducible, scalable, and globally relevant therapeutic.
