In microbial communications, the belief that there is widespread competition was accepted; however, a recent study revealed that bacterial species assist each other much more frequently than previously thought .

Massachusetts Institute of Technology and Broad MIT Institute, Harvard Paul C. Blainey and the Hebrew University of Jerusalem Jonathan Friedman found that the percentage of matches between bacterial species More than 35 have been observed to help at least one of the two species grow. The authors of the study; He is of the opinion that the data obtained can be used to guide improvements in bacterial growth through matching compatible species.

It was observed that the effect of growing conditions on the interaction between species is great

Growing in 40 nutrient conditions that differ in terms of carbon amount and type In the research where 20 soil bacteria species were tested; In order to understand how bacterial species affect each other’s growth, a series of double-dolls, one of which is labeled with fluorescence and the other is not labeled, was produced. Using fluorescence measurements to monitor the growth of etikedollarsy species in pairs and singly, the researchers changed which species was labeled and repeated each pairing twice , measuring more than 180,000 interactions. If a mating caused either species to grow faster than alone, the researchers rated this result as a positive interaction , even if the enhanced species slowed the growth of the mate. It has been observed that in such situations of ‘interference’ the weaker side is often exploited at the expense of the stronger.

The researchers concluded that the relationship between any pair of species is strongly related to rearing conditions . Many of the species pairs showed different types of interactions depending on the carbon source. Noting what will happen in one setting based on what’s going on in the other is often wrong , Friedman said , “You change the environment, and the interaction can change not only quantitatively but also qualitatively.” used the expressions. In addition, Friedman; noted that the research findings could be used in synthetic ecology or engineering , since stimulating the growth of one microbe can lead to the presence of another microbe that grows well in that environment.

Sara Mitri , who studies microbial ecology at the University of Lausanne , said the study is extremely important, noting that the extent of beneficial interactions between bacteria “long-standing” and He says it’s a question that’s “hard to test on such a large scale” . The findings also overlap with findings that Mitri cites observing with similar species in his lab. These beneficial interactions between bacteria can play an important role in shaping microbial ecosystems . Believing researchers don’t yet know what triggers the different bacterial interactions . Blainey stated that they hope their work will excite other researchers , “It’s definitely a part of this detailed mechanistic study of researchers specializing in some of these organisms or the metabolism of some of the specific carbon sources. base part I hope you will,” says.
