In particular, the transparent gut, rapid growing time, and ability to create a defined gut microbiota make it an ideal candidate organism for understanding and engineering the host microbiota. Here we present the development of an experimental model that can be used to characterize whole-cell bacterial biosensorsin vivo. A dual-plasmid sensor system responding to isopropyl -d-1-thiogalactopyranoside was developed and fully characterizedin vitro. Subsequently, we show that the sensor was capable of detecting and reporting on changes in the intestinal environment ofC. elegansafter introducing an exogenous inducer into the environment. The protocols presented here may be used to aid the rational design of engineered bacterial circuits, primarily for diagnostic applications. In addition, the model system may serve to reduce the use of current animal models and aid in the exploration of complex questions within general nematode and hostmicrobe biology.
