New discovery: "photosynthesis inverse" helps reduce pollution
Plant biomass was the result of the photosynthesis of plants due to the sunlight. Part of the light will convert into chemical energy in plants helps link the atoms into molecules of carbohydrates. The amount of carbon accumulation of tree biomass grows greater.
The industrial production process currently is based mainly on the petrochemical industry, the use of oil and natural gas to create the material. This pull in high pollution and cause harm to the environment. But scientists from the University of Copenhagen (Denmark) announced that they have just found a way to better.
Study published in full text on the Nature Communications pointed out: through the process of "reverse of photosynthesis"-a process of decomposition of biomass to generate energy and chemical-contamination will be minimized. Besides, the power gain is also faster, higher performance.
Biological knowledge in school we were taught is that trees grow through photosynthesis-capable of converting light energy into chemical energy to use. But with the "inverse photosynthesis", solar energy is used to decompose the plant material rather than help them increase.
Professor Claus Felby, who led the research said: "this is a change, it changes the production in the industry and chemicals, thus reduce pollution dramatically." He added that: "photosynthesis by the Sun not only help big tree up that similar principles also apply to substances in the plant, releasing chemicals. This has always been so, but no one ever noticed.
In other words, direct sunlight promote chemical process. Energy from sunlight can be used to process then takes place continuously without the need for additional input energy ".
Dr. Benedikt Klaus Møller stated: "we use the term" photosynthesis "invert (reverse photosynthesis) because the enzyme uses oxygen in the atmosphere and the sun rays to break down and convert carbon link in the tree in the middle of other things instead of building cool and producing oxygen as the way we do according to the knowledge of normal photosynthesis".
According to the research group, the sunlight are chlorophyll molecules gather and combine with the natural enzyme called monooxygenases. When this enzyme is exposed to sunlight, the process accelerated decomposition.
While the process of creating biofuels or other materials from biomass plants can take a long time, then reverse the photosynthesis has vowed to cut the time down to only a few minutes.
Dr. David Cannella explains: "this discovery means that by using sunlight, we can produce biofuels and biochemical for things like plastic faster, at a lower temperature than with higher energy efficiency levels. In some reactions that currently take 24 hours complete then just 5-10 minutes if using the Sun ".
The researchers said that the findings showed that potential decomposition chemical bonds between carbon and hydrogen-methane gas can turn into methanol. This liquid is used in the fuel industry, materials and chemicals.
