PETRI_PRINTED WALLPAPER

Creating living wallpaper with bacterial pigments

The Motivation

In face of the climate crisis, industries across the board are looking towards science for new technologies and regenerative alternatives for current manufacturing processes. Primordial Patterns ignites interest in new applications of biodesign and bacterial pigments in the wallpaper industry. 

Why Bacteria

Bacterial Pigments are a source of readily available, naturally derived pigments that can be grown anywhere independent of season and weather conditions. They have enormous advantages including rapid growth, easy processing, and antimicrobial properties.

EXPERIMENTATION

Prototype 1

After the tools had run through the autoclave, a pressure sterilizer, I formulated the right agar recipe to provide the exact nutrients for the bacteria strains Serratia marcescens and Janthinobacterium lividum. The linocuts were pressed into the agar plate, and the liquid bacteria culture was painted into the relief.

Prototype 2

For test 2, cast silicone molds were used to control dispersion of the agar. Serratia marcescens was tested as it has a fast growth rate of only several days.
