Creepy Cultures 2023

by | Contests

Publish Date: October 2, 2023

The autumnal equinox occurs each September in the northern hemisphere, signifying the end of Summer and beginning of Fall. There are many things we get excited for in the Fall like seeing the leaves change colors, wearing our cozy sweaters, enjoying comfort food, smelling the crisp air, and of course, pumpkin spice everything. At Microbiologics, Fall also means it’s time for our favorite agar art contest, Creepy Cultures! If you’re a spooky season fanatic, this one’s for you.

Each October, we ask our fellow microbiologists to showcase their skills by creating Halloween-themed agar art. Agar art is created by using sterilized applicators  to “paint” or “draw” with microorganisms on a “canvas” of culture media. Artists get creative with their materials by combining certain microorganism species and culture media types to achieve a specific look.

Our team is always amazed by the Creepy Cultures you submit every year with everything from haunting ghosts, to cute pumpkins, funny pop-culture references and scary spiders!
