E. coli (E. E. E. e. e. e. because of its susceptibility to infection and causing various discomforts) coli) is notorious. But it turns out that E. coli also has an undiscovered side, and that it can become the bacteriological community’s Claude Monet (French impressionist painter). Researchers at the University of California, San Diego, recently found that mixing E. coli with bacillus bacteria on the surface of agar in a petri dish produces a stunning flower-like pattern.
Under normal circumstances, E. coli does not move well on agar, but shellfish can easily spread throughout the growth medium. Put the two together, as the colonies grow, when other bacteria on the E. coli “hitchhiking”, they form a scenic pattern.
The team published the findings in the journal eLife in the hope of helping scientists learn more about how bacteria form together. Liyang Xiong, lead author of the paper, said: “We actually mixed the two bacteria together for another project, but one morning I found a mysterious floral pattern in a Pyces petri dish, and the beauty of the pattern touched me. I began to wonder how bacterial cells interacted with each other to become an artist. “
