不同的微生物可以产生不同的蛋白酶,可以适应不同的工业要求,如pH值,温度,和压力。来自微生物的耐盐蛋白酶(STPs)表现出较高的耐盐性,更广泛的适应性,和更有效的催化能力在极端条件下相比,传统的蛋白酶。这些独特的酶在包括食品在内的各种行业中具有广阔的应用前景。医学,环境保护,农业,洗涤剂,染料,和其他人。关于微生物来源的STP的科学研究已被广泛报道,但是对微生物来源的STPs及其在高盐常规大豆可发酵食品中的应用却很少有系统的综述。这篇综述介绍了产生STP的微生物种类及其选择方法,并对微生物的耐盐机理进行了总结和分析。它还概述了从微生物中分离和纯化STP的各种技术,并讨论了STP的耐盐机制。此外,这篇综述展示了现代生物技术在筛选新型微生物来源的STP及其耐盐性方面的贡献。突出了耐盐微生物和STP在高盐传统大豆发酵食品中的潜在应用和商业价值。审查结束时,就微生物来源的STP的挑战和未来方向进行了总结。这篇评论提供了对分离的宝贵见解,净化,性能增强,以及微生物源STPs在传统发酵食品中的应用。
Different microorganisms can produce different proteases, which can adapt to different industrial requirements such as pH, temperature, and pressure. Salt-tolerant proteases (STPs) from microorganisms exhibit higher salt tolerance, wider adaptability, and more efficient catalytic ability under extreme conditions compared to conventional proteases. These unique enzymes hold great promise for applications in various industries including food, medicine, environmental protection, agriculture, detergents, dyes, and others. Scientific studies on microbial-derived STPs have been widely reported, but there has been little systematic
review of microbial-derived STPs and their application in high-salt conventional soybean fermentable foods. This
review presents the STP-producing microbial species and their selection methods, and summarizes and analyzes the salt tolerance mechanisms of the microorganisms. It also outlines various techniques for the isolation and purification of STPs from microorganisms and discusses the salt tolerance mechanisms of STPs. Furthermore, this
review demonstrates the contribution of modern biotechnology in the screening of novel microbial-derived STPs and their improvement in salt tolerance. It highlights the potential applications and commercial value of salt-tolerant microorganisms and STPs in high-salt traditional soy fermented foods. The
review ends with concluding remarks on the challenges and future directions for microbial-derived STPs. This
review provides valuable insights into the separation, purification, performance enhancement, and application of microbial-derived STPs in traditional fermented foods.
