‘Tis the season to be merry, and what better way to spread holiday joy than showcasing it through a petri dish? In this blog, we explore the magical and diverse world of microbiology. Beyond their often misunderstood and scary reputation, microorganisms hold an array of benefits for us, as they can be used not only for scientific advancements but also for artistic expressions – yes, even if you aren’t a skilled artist!
The Bacteria behind the photos
Our Christmas art started by selecting PCA (Plate Count Agar), Mannitol Salt Agar, and Bacillus Cereus Agar as our canvas, providing diverse growth conditions for our chosen bacterial residents.
After, we selected different strains of bacteria, such as E. coli, MRSA (Methicillin-resistant Staphylococcus aureus), and Salmonella spp to make the outline of the drawings, in a controlled environment. Next, we incubated the plates for 24 hours, for the bacteria to work their magic. The agar plates transformed into fun drawings, showcasing the festive Christmas spirit.
