A comprehensive review on microbial urease: features and industrial applications

Résumé fourni par la source

) by James B. Sumner in 1926, has become a cornerstone of biotechnology. The global urease market, dominated by plant-based sources, was valued at USD 1.24 Billion in 2024 and is projected to grow at a CAGR of 5.5%, reaching USD 1.94 billion by 2033. However, plant-derived ureases face challenges, such as low extraction efficiency, variability in yield due to plant maturity, and sensitivity to environmental factors, limiting scalability. Microbial ureases, globally embraced due to escalating demand, offer superior stability across extreme pH and temperature ranges. These attributes confer broad potential applications in diverse fields, such as: agriculture, environmental, clinical, and healthcare industries. Nevertheless, the industrial production of microbial urease continues to encounter obstacles, including elevated purification costs and the lack of cost-effective optimization strategies. This review provides quantitative insights into microbial ureases from bacteria, fungi (excluding hemiascomyces), and diatoms, highlighting their catalytic efficiency, Ni-dependencies, and advancements in assay techniques and enhanced purification strategies. It explores applications across agriculture, bioremediation, and self-healing concrete, emphasizing ureolysis-driven microbially induced carbonate precipitation (MICP) as a promising eco-friendly and sustainable approach, thus providing a scientific and reasonable reference for their large-scale application.
