Figure 3. Biofilm utilization for patterning and biomaterial production.

Figure 3.

A) Optogenetic biofilm patterning using light-switchable c-di-GMP regulation. BphS activated by near-infrared light synthesizes c-di-GMP, while BlrP1 activated by blue light degrades c-di-GMP, resulting in biofilm formation and dispersal, respectively [biofilm images from (Huang et al., 2018)]. B) pMag on the microbial surface and nMag on the material surface form heterodimers with blue light. C) Engineered microbe produces the self-assembled curli nanofiber CsgA with a variable peptide domain, which confers new functions.
