It is only because the difference in carbon sources will affect the reproduction and glycolytic metabolism rate of yeast itself, which in turn affects the overall lactate secretion level. However, these do not affect our project. Later, the promoter of the ldhA gene will be changed to the pFUS1 promoter regulated by the downstream of the yeast mating pathway, and the promoter of the receptor will also use the constitutive promoter in yeast.</p> + <p>Although the experimental results are in line with our expectations, unfortunately, knocking out the mating pathway in yeast itself cannot completely remove the nonspecific noise. Moreover, what is more confusing is that the specific signal of the group induced by galactose is reduced after gene knockout. We tried to explain and solve this problem, but due to the time limit of the iGEM competition, we did not achieve good results. For more details, please see wet lab. </p> </div> </div> -- GitLab
