Faster bacterial breathing increases carbon emissions

LONDON, Nov. 12 (Xinhua) -- Researchers at Imperial College London have found that as bacteria adapt to higher temperatures, they can breathe faster and release more carbon, accelerating global climate change, according to research published in the Journal of Nature.
bacteria and paleontogens, collectively known as prokernel organisms, exist on every continent and account for about half of the world's living things.
most primary nuclear organisms breathe like humans, consuming energy and releasing carbon dioxide (CO2). The amount of CO2 emitted depends on the rate of respiration of the original nucleus, which changes with the temperature of the outside world.
so far, the relationship between temperature, breathing rate and carbon emissions has not been determined. By collecting and analyzing data that analyzed the rate of breathing of 482 primary nuclear organisms as they changed with temperature, the researchers found that most primary nuclear organisms increased their carbon emissions even more at higher temperatures.
, who is the project leader and is in the Department of Life Sciences at Imperial College, said: "In the short term, from a few days to a few hours, the metabolism of individual primary organisms accelerates and produces more CO2. But there will be a maximum temperature at which their metabolism becomes inefficient. In the long run, he points out, these primary nuclear community will evolve more efficiently over time at higher temperatures, further improving their metabolism and carbon emissions. As a result, rising temperatures will allow many primary nuclear biomes to operate more efficiently in the short and long term, thereby contributing more to global carbon emissions and the resulting temperature increases.
researchers compiled the responses of primary nuclear organisms from around the world and under different conditions to temperature changes, from Antarctic saltwater lakes below 0C to hot tubs above 120C. They found that primary nuclear organisms usually showed strong reactions to temperature changes in the medium temperature range (below 45 degrees C), increasing breathing in both the short term (days to weeks) and the long term (months to years). There is no such reaction in the higher temperature range (above 45 degrees C), but they are unlikely to be affected by climate change because they are active at such high temperatures in the first place. The short-term response of central cogenerogens to climate change is greater than that of ethonal organisms (more complex cellular organisms).Thomas Smith, ph.D. student in the Department of Life Sciences at Imperial College, the lead author of the
study, said: "Most climate models currently assume that all organisms react to temperature in the same way, but our research suggests that bacteria and paleontums may deviate from the 'global average'. "He believes that given that these microorganisms may be important contributions to total respiratory and carbon emissions in many ecosystems, climate models should take full account of their more sensitive response to temperature changes in the short and long term, which will help to create more accurate models of future climate change."
