       <p>To better construct the subsystem of muscone-induced lactate secretion, we split it into two parts: one is lactate secretion, and the other is the muscone switch. We only merged the two parts together after confirming that both parts can work normally. This project is divided into three main cycles.</p>

       <p>To better construct a subsystem that allows Saccharomyces cerevisiae to colonize IBD lesions, we divided it into two sub-parts: one part is the IBD signaling molecule receptor, and the other part is the adhesion protein. Only after confirming that both parts are functioning properly will we combine these two sub-parts. This section is divided into two main cycles.</p>
