Description

Design

Figure 1: pGH3CF construct schematic

To test out the functionality of the driver circuit, a construct with 3C120-CYC-LacO controlling the FLO1 gene was designed (figure 1). Anticipating the need to test integration, this plasmid was also designed to include the HBD2 gene under the control of the GAL1 promoter.

Usage

This part requires the host organism to be able to express BBa_K3570021 for it to work.

Characterization

Blue light induced flocculation protocol was replicated for pRL3CM(BY474D), based off existing protocol used for characterization of blue light induced flocculation. The reduction in OD600 after 24 hours of flocculation as well as the unflocculation index plotted.

Please refer to https://2021.igem.org/Team:NUS_Singapore/Results for more information on the data and work done to characterize this part.
