We realized that the most convenient way to highlight the presence of the probiotics, and hence, the presence of the tumors, was to get these bacteria to produce a signal that would be detectable in the urine, and so we specifically programmed these probiotics to make a molecule that would change the color of your urine to indicate the presence of cancer.
我们意识到最简便的 标记出益生菌， 进而让肿瘤现形的方式， 是让这些益生菌产生 可以在尿液中被检测到的信号， 所以我们特别编译了这些益生菌， 让它们产生可以改变 你尿液颜色的分子， 以此实现癌症的检测。
