C-MOULD, the world’s largest collection of microorganisms for use in the arts, with over 50 different kinds of microorganism. We have bacteria and fungi that glow in ethereal shades of green and blue light, bacteria that make gold and electrically conductive nanowires, and bacteria that produce biotextiles. We also possess the largest collection of pigmented bacteria. Here is the palette of living colours that is available through C-MOULD. Behind the obvious colour, each bacterium has its own unique personality and history (see below) and when used in paintings each one adds it own character to the work.

“If you ever fly over San Francisco Bay, be sure to peer out of the window to catch a glimpse of one of the world’s most incredibly colored landscapes – the salt evaporation ponds operated by Cargill, Inc.
Salt evaporation ponds are shallow artificial ponds designed to produce salts from sea water or other brines. The seawater or brine is fed into large ponds and water is drawn out through natural evaporation which allows the salt to be subsequently harvested. During the five years it takes for the bay water to mature into salt brine, it is moved from one evaporation pond to another. In the final stages, when the brine is fully saturated, it is pumped to the crystalizer where a bed of salt 5 to 8 inches thick is ready for harvest.
Salt ponds range from blue green to deep magenta – colored naturally by the microorganisms that thrive as salinity levels increase. The color indicates the salinity of the ponds and the type of microorganisms that’s breeding on it. Three microorganisms in particular, Synechococcus, Halobacteria, and Dunaliella, influence the color of salt ponds.”
