Our gut microbiome contributes to cravings

According to an April 26 2022 Medical News Today report, microbes contribute to our cravings and play a major role in our processing of nutrients.

These are based on mice studies by Dr. Kevin Kohl, assistant professor in the Department of Biology at the Kenneth P. Dietrich School of Arts and Sciences at the University of Pittsburgh and Dr. Trevelline, Rose postdoctoral fellow at the Cornell Lab of Ornithology.

Dr. Trevelline said the microbes in the gut were beneficial contributors to a lot of processes, particularly by synthesizing the nutrients humans need and supplementing our diets.

Their research showed that the mice that received diverse types of microbiota voluntarily changed their diet preferences. “Our work shows that animals with different compositions of gut microbes choose different kinds of diets,” Dr. Kohl said.

Drs. Trevelline and Kohl also discovered that that varying levels of tryptophan in mice’s blood led to their choosing different diets, according to the Medical News Today article.

MIT develops bacteria that breaks down antibiotics

source: source:
MIT News reported April 11 2022 that MIT researchers successfully engineered a bacteria based antibiotic treatment. The enzyme of this bacteria can help reduce the risk of inflammation caused by antibiotics.

MIT engineers developed a strain of bacteria that is safe for human consumption that safely produces an enzyme that breaks down a class of antibiotics called beta-lactams. These include ampicillin, amoxicillin, and other commonly used drugs, according to the MIT News article.

James Collins, the Termeer Professor of Medical Engineering and Science in MIT’s Institute for Medical Engineering and Science (IMES) and Department of Biological Engineering, and the senior author of the new study, refers to this application as “living biotherapeutics”.

Researchers near replicating carbon reduction process in nature

source: source:
Researchers found that enzymes from certain bacteria in the soil turns carbon dioxide in the air into carbon molecules, a process that helps reduce the carbon footprint which drives climate change.

An international consortium of university researchers including Stanford’s Department of Energy’s SLAC National Accelerator Laboratory have figured out a way to potentially artificially duplicate the process in lab, according to an April 29 2022 report by Glennda Chui of the Stanford National Accelerator Lab.

The process known as carbon fixing, is the key component in photosynthesis. But instead of a 20 times slower process in plants, the soil bacteria, Kitasatospora setae, relies on enzymes called Rubisco. Researchers also found it can also produce antibiotics, according to Chui’s article quoting Soichi Wakatsuki, a professor at SLAC and Stanford.

The next step will be to build on an enhanced version of the artificial process.
