Genetic Engineering of Microorganisms for Industrial Biocompound Production

Abstract

The production of biocompounds using genetically engineered microorganisms has emerged as a promising and sustainable alternative to conventional extraction and chemical synthesis methods. This review provides a comprehensive overview of recent advances in genetic engineering strategies, including gene insertion, gene knockout, CRISPR-based genome editing, metabolic pathway engineering, and metabolic flux optimization, for enhancing biocompound production in microbial systems. The development of microbial cell factories based on bacteria, yeast, filamentous fungi, and emerging platforms has significantly improved the efficiency, scalability, and versatility of biotechnological processes. The applications of microbially derived biocompounds across various industries, including pharmaceuticals, food, agriculture, cosmetics, and chemical manufacturing, are discussed, highlighting their functional diversity and industrial relevance. Despite substantial progress, several challenges remain, such as metabolic complexity, strain stability, process scalability, and economic feasibility. The review further explores current limitations and discusses future perspectives, emphasizing the role of synthetic biology, omics technologies, and artificial intelligence in advancing microbial production systems. This study underscores the transformative potential of engineered microorganisms in the sustainable production of high-value biocompounds and provides insights into future research directions and industrial applications.
