Beef soup! You’d usually count on it to be someplace from reddish-brown to gray, relying on how nicely it was cooked and ready. Nevertheless, surprisingly, an assistant professor discovered the meat soup of their fridge had mysteriously turned blue. That spawned an investigation into the trigger which remains to be ongoing.

[Dr. Elinne Becket] has earned her stripes in microbiology, however the blue soup astounded her. Regardless of her years of expertise, she was unable to guess on the course of or a supply of contamination that would flip the soup blue. Certainly, only a few pure meals are blue in any respect. Even blueberries themselves are extra of a purple coloration. The case sparked sufficient curiosity that [Elinne] went again to the trash to gather photographs and pattern for analysis on the request of others.

Up to now, metagenomic DNA evaluation is ongoing and samples of the soup have been cultivated in petri dishes. Early evaluation exhibits that a few of the microbes type iridescent colonies, One other researcher is attempting to find out if the bugs from the soup could make blue coloration seem on tender cheese. There’s some suspicion {that a} micro organism often known as pseudomonas aeruginosa may very well be the reason for the blue coloration, however that presents its personal issues. P. aeruginosa is assessed as a Biosafety Degree 2 pathogen which might require some researchers to desert work on the undertaking for security causes.

The jury’s nonetheless out on this microbiological thriller. When you’ve bought some concepts on what may very well be happening, tell us within the feedback!
