Israeli researchers have developed only bacteria fed with carbon dioxide by the Weisman Institute of Science (WIS) in central Israel, reported Wednesday. These bacteria, which make up the entire biomass of their bodies from carbon in the air, help reduce greenhouse gas accumulation in the atmosphere and develop future technologies in the fight against global warming, reports Xinhua can do.
According to the study, published in the journal Cell, these bacteria were completely removed from sugar, after a decade-long process.
Israeli scientists have been able to “reprogram” E.coli bacteria, which consume sugars and release carbon dioxide, so they use carbon dioxide from the environment and produce the sugars that give them their bodies Is required to be constructed.
The researchers mapped the genes that are required for this process and incorporated some of them into the genome of the bacteria in their laboratory.
In addition, they have introduced a gene to bacteria that allows them to obtain energy from a substance called formate.
This was not enough for bacteria to change their diet, and “lab development” procedures were needed to gradually shut down sugar.
At each stage of this process, cultured bacteria received small amounts of sugar, as well as abundance of carbon dioxide and formate.
The lineage of the bacteria was gradually removed from sugar dependence until, about six months after adjusting to the new diet regime, some traded full nutrition.
Researchers believe that the “healthy” habits of these bacteria may prove to be mostly healthy for the Earth.
