Abstract
Background: Active Pharmaceutical Ingredients (APIs) are fundamental components that provide therapeutic efficacy to medications, yet traditional discovery methods are limited in innovation and diversity, hindering the development of novel therapeutics. This has led to a renewed interest in microbial species as a source of bioactive compounds, particularly as the pharmaceutical industry faces stagnation in API procurement and environmental concerns regarding traditional extraction methods. Methods: This review discusses the potential of microorganisms—including bacteria, fungi, algae, and archaea—as sources of APIs. The exploration involves analyzing microbial diversity, biosynthetic pathways, and advancements in biotechnology such as genetic engineering, synthetic biology, and metagenomics. The review also highlights traditional culture-based techniques and contemporary high-throughput screening methods used in microbial API discovery. Results: The findings reveal that microorganisms possess complex metabolic processes that enable the production of diverse bioactive compounds. Advances in genetic profiling and bioprocessing technology facilitate the efficient identification and cultivation of promising microbial strains. Key examples include antibiotics derived from bacteria and antifungal compounds from fungi, illustrating the therapeutic potential of these organisms. However, challenges such as production yield optimization and regulatory hurdles remain significant. Conclusion: Microorganisms represent a vast and underutilized reservoir of potential APIs that could significantly impact the pharmaceutical landscape. By optimizing their metabolic diversity through innovative biotechnological strategies, the industry can overcome current limitations and meet emerging therapeutic needs sustainably. Future prospects include tailored microbial factories for personalized medicine and collaborative frameworks to expedite the transition from discovery to commercialization, ensuring a broad and lasting impact on global health.
