New biosolar cell closes green gap

For millions of years, plants have been generating energy from photosynthesis. This complex biochemical process is controlled by two major proteins: the photosystems (PS) I and II. These natural photosynthetic protein complexes are also the heart of biosolar cells. They enable the conversion of the energy of sunlight into chemically bound energy. A special role is played by PSII, which can use water as an electron source for power generation. However, the green part of the sunlight has not been usable so far.

Bioeconomy project nominated for EU prize

The countdown has started: On July 9th the winners of the REGIOSTARS Awards will be announced by the European Commission. The prize is awarded annually as part of a competition to innovative EU regional funding projects. This year's nominees include the INTERREG V A-project "Bioeconomy-Green Chemistry" of the Ems-Dollart-Region (EDR). The team is competing with more than 50 applicants in the category "Circular economy for a green Europe" for the victory. The prize is awarded in a total of five categories.

Vanilla aroma from lignin

Vanillin gives the vanilla bean its characteristic flavor. It is one of the most frequently used flavoring substances in food and perfume production, but also in the production of pharmaceuticals. Several tens of thousands of tons are used annually. Until now, however, artificially produced vanillin has been made from petroleum, creating toxic waste. Researchers at the Johannes Gutenberg University in Mainz (JGU) have now succeeded in developing a sustainable method for obtaining the coveted aroma substance. A team led by Siegfried Waldvogel used the biopolymer lignin - a wood component tha

Bioprocess developed for plant hormone

Scientists at Bielefeld University have succeeded for the first time in enzymatically producing 12-oxophytodienoic acid (12-OPDA), a central precursor of the plant hormone jasmonic acid. The jasmonates are derived from the acidity, by means of which plants react to injuries, warn each other of pests or also control fruit ripening: "For example, jasmonic acid can trigger the release of toxic substances such as nicotine in the leaves, which harm the attackers", explains biologist Karl-Josef Dietz. "Jasmonic acid also has healing properties and can induce damaged leaves to regenerate."

Neue Biosolarzelle schließt Grünlücke

Seit Millionen von Jahren gewinnen Pflanzen Energie aus der Photosynthese. Dieser komplexe biochemische Prozess wird von zwei großen Proteinen gesteuert: den Photosystemen (PS) I und II. Diese natürlichen Photosynthese-Proteinkomplexe sind auch das Herzstück in Biosolarzellen. Sie ermöglichen die Umwandlung der Energie des Sonnenlichts in chemisch gebundene Energie. Eine besondere Rolle spielt dabei das PSII, das Wasser als Elektronenquelle für die Stromerzeugung nutzen kann. Der Grünanteil des Sonnenlichts war bisher aber nicht nutzbar.
