The world of bacteria and mold is diverse. Sometimes considered invaders or contaminants, these microorganisms adapt so as to live almost anywhere. They perform important interactions with other organisms and their surrounding environment.

“Ground dwellers” is a group of bio-art in Petri dishes that incorporates a collection of microorganisms present in the soil where corn is cultivated. Corn is Mexico’s staple and single, most important nutrition source. The conservation of these micro-ecosystems assures future corn production, innovation in fertilizer creation and biological pest control.

The collection of species was obtained by the researchers at CNRG (National Center of Genetic Resources). This is a government institution that is committed to obtaining, characterizing and preserving species important for Mexico’s biodiversity.

The technique used in this bio-art is a collage of microorganisms previously grown in agar medium and cut in different shapes to form the piece.

As using colors in a painting, the different morphology and biochemical reactions with the agar medium of each type of microorganism were used to create patterns and designs.

Even their luminous reaction to UV light makes a new way of seeing bacteria.
