<p>We have decided to design an affordable, promising, and efficient microbial therapy for IBD, called Muscure. To comprehensively and effectively promote the development of Muscure, we follow the engineering cycle recommended by iGEM at each stage of our work. Each engineering cycle consists of four interconnected and sequentially progressing steps: design, build, test, and learn. In this way, with well-organized division of labor and cooperation, we have achieved rapid iteration of the project. In many cases, we have been able to effectively solve the difficulties we encounter and obtain the results we initially expected for the design.</p>
