Tobacco as an alternative for producing bioethanol

16-04-2014

Researchers at the NUP/UPNA-Public University of Navarre and the IdAB-Institute of Agrobiotechnology have conducted a study into genetically modified tobacco plants from which it is possible to produce between 20 and 40 per cent more ethanol; this would increase their viability as a raw material ...

Dual role of carbon dioxide in photosynthesis

16-04-2014

Researchers at Umeå University have found that carbon dioxide, in its ionic form bicarbonate, has a regulating function in the splitting of water in photosynthesis. This means that carbon dioxide has an additional role to being reduced to sugar. The pioneering work is published in PNAS. It is ...
