A biologist investigates why the beef broth in the fridge suddenly turned blue – GIGAZINE

by Gerwin Sturm

Experiences like “the leftovers have turned green because of mold” are common, but you shouldn’t hear many reports of the food turning blue. An assistant professor of biological sciences at California State University, San Marcos, was surprised to find that beef broth in the refrigerator had turned blue and began to investigate.

You can check out the blue beef soup found by Mr. Erin Beckett, who specializes in biological science, from the following tweets. As leftover food is reflected in this picture, you need to be careful when looking at it, and Mr. Beckett also places the photo as “sensitive” content.

Other biologists who saw this photo on Twitter were intrigued. Investigate the cause of the soup’s discoloration and encourage Mr. Beckett to write a paper.

Mr. Beckett to get the sample while pinching his nose at the terrible stench.

Biologist Sebastian Kociova, who collaborated with Mr Beckett, found that the micro-organisms contained in the blue soup formed rainbow colored colonies. According to Kosiova,bacillusMany of the known microorganisms appear to be able to form patterns that reflect light like an oil film.

Mr Koshioba conducts experiments by combining several micro-organisms and cheese to explain the mystery of beef soup turning blue. Mr Koshiova cools the micro-organisms by predicting that “it could have been activated by being placed in a low temperature environment and turned blue.”

Microbiologist Nick Coleman says, “Milk and meatTryptophancontains lots of Many microbes do thisTryptamineorindole, and oxidized to dye indigo or a color close to it. Perhaps this is the reason why the blue soup was born.”

In response to these signs, Mr. Beckett and Mr. Kosiova is working to explain the mystery, but at the time of writing the article, the reason for “why it turned blue” has not been found at the time of writing this report. the article. “The project is in full swing,” Kosiova said.revealand waiting for Mr Beckett, who is infected with the new coronavirus, to recover.

The series of riots was tagged with the hashtag “bluesoup” and spread information on Twitter, and finally it was published as a small story in the authoritative scientific journal MIT Technology Review.publishShe has been.

Also, when Mr. Beckett asked, “Are there mass spectrometry experts?” Through this hashtag, a microbiologist at the University of California, San Diego volunteered to cooperate.
