Microorganisms are cultured in certain patterns to produce artwork known as microbial art, agar art, or germ art. The microbes utilized can be bacteria, yeast, fungus, or less typically, protists. The bacteria may be chosen for their inherent coloration or may be genetically modified to express fluorescent proteins, which will cause them to fluoresce when examined under ultraviolet light. Pigmented or fluorescent bacteria and yeasts act as the paint, and agar plates serve as the canvas. After a suitable amount of incubation, epoxy is used to seal the microbe culture in order to preserve the work of microbial art.
Have you ever witnessed living, developing microorganisms being used to produce art in a petri dish? Agar art that! The creators employ different kinds, forms, and sizes of agar as a "canvas" with either naturally colored microbes, such the red bacteria Serratia marcescens, or genetically modified microbes, like the yeast Saccharomyces cerevisiae altered with violacein genes. In actuality, none other than Alexander Fleming himself was the first agar artist!
What is Agar Art?
The manipulation of bacterial colonies on agar plates is the process used to create agar art. In laboratories, agar, a jelly-like substance derived from seaweed, is frequently employed as a medium for the development of microorganisms.

How to Create Agar Art?
The preparation of the agar plates, inoculation with bacteria or fungi, and manipulation of the growth to produce a design are all steps in the process of creating agar art. The general procedures for making agar art are as follows:
Get agar plates ready: Typically, agar plates are made by sterilizing an agar and nutrient solution on a petri dish. Once the agar mixture is liquid, it is placed into the petri dish and given time to cool and solidify.
Inoculate the plates: Using a sterile loop or swab, inoculate the agar plates with a little amount of bacterial or fungal culture after they have set. The plates that have been inoculated are then kept in an incubator at the right temperature and humidity levels for the organism to develop.
Manipulate the growth: After the bacteria or fungi have developed on the agar surface, the artist can start manipulating the development to produce a design. To do this, apply the bacterial or fungal cultures to the surface of the agar using a number of equipment, such as cotton swabs, pipettes, or toothpicks.
After the design is finished, the agar plate is incubated once more to allow the bacterial or fungal growth to mature. Then it is photographed. The finished agar art can be photographed or displayed, but it shouldn't be eaten because it might contain dangerous bacteria.
To prevent contaminating the cultures and maintain safety, it is crucial to follow appropriate laboratory safety procedures and work in a sterile atmosphere.
What Media is Agar Art?
Agar is a solid culture medium that is frequently used in microbiology to grow and cultivate microorganisms. Agar is a sort of solid culture media manufactured from seaweed extracts. Because agar is transparent, the growth patterns of bacteria and fungi can be seen clearly and it offers a nutrient-rich and stable environment for them to thrive in. The growth of various microbes can be supported by combining agar with a range of nutrients, and the visual appeal of the artwork can be improved by adding colors or pigments to the mixture.

Conclusion
Artwork made by cultivating microorganisms in certain patterns is known as agar art, microbial art, or germ art. The microbes used can be protists, yeast, bacteria, or fungi (less commonly). The natural colors of the bacteria can be used to choose them. As seen in the above image, the organisms that are most frequently used and accessible are Serratia marcescens, Pseudomonas aeruginosa, and Staphylococcus aureus. Sir Alexander Fleming, the man who discovered penicillin in the 1920s, started creating "germ paintings" of bacteria during his career as a microbiologist, so painting with germs isn't wholly new.
Similarly, green fluorescent protein (GFP) was discovered by scientist Roger Tsien, who received the 2008 Nobel Prize in chemistry for his contributions to this field. Nathan Shaner, a researcher, created a microbial artwork depicting a San Diego beach scene in 2006 using GFP.
