Microbial Art

The range of colored pigments produced by different actinobacteria, coupled with their tendency for non-lateral growth, make them suitable for creating biological art. Creating and observing biological art can be used as a vehicle to engage people with diverse backgrounds and interests in both concepts and techniques related to chemistry and biology.1

“Agar art” has been shown to be an effective method for increasing confidence in students being introduced to microbiology.2 Similarly, as long as proper sterile conditions are available, creating art using Streptomyces has been an engaging activity for introducing high school students to microbiology and working with elementary school populations. BioArt employing actinobacteria can therefore be used to introduce both younger students and artists to science, including those from traditionally marginalized identities in STEM.3

The following strains are streaked, using sterile technique, on R5 media in order to “draw” with their pigments. The strains can also be streaked on a modified, less expensive media using food-grade agar and/or chicken broth. Pigments appear after 3-7 days of growth.1 All Streptomyces strains are classified as Biosafety Level 1 (BSL-1) organisms, and are of minimal hazard to humans.4

  • Streptomyces coelicolor (Blue, Red under acidic conditions)
  • Streptomyces violaceoruber (Purple, Pink under acidic conditions)
  • Streptomyces roseofulvus (Yellow)

The colored pigments can also be extracted, dried, and resuspended in acrylic to produce bio-based paint.

Using standard 100 mm petri dishes allows for smaller-scale activities, which is often preferable when introducing proper bacterial streaking technique so that participants can create multiple pieces of art. However, using larger plates allows experienced artists to create much more detailed and intricate drawings.

The characteristic colored pigments produced by actinobacterial strains enable concurrent learning opportunities about molecular color and natural products. While leading or introducing the activity, participants may be interested to learn that biosynthesized molecules are responsible for the drawing’s vibrant color and that these molecules can have antibiotic and anticancer properties.
