One group of scientists from Texas A&M University have come up with a solution: using plants to make the enzymes. Professor Zivko Nikolov, who leads the Bioseparations Lab, will describe their research on Monday 7th July at the Society for Experimental Biology's Annual Meeting in Marseille [Session P2].
Traditional methods of generating enzymes for biofuel production currently operate at over five times the target cost required to make the fuels financially competitive. By using plants which have been engineered to make the proteins, Professor Nikolov believes that the target can be met. His group, which has expertise in the development of economic processing techniques, have designed processing strategies which allow multiple products to be obtained from each crop, making the whole process more economically viable.
"One of our projects focuses on producing cellulases, enzymes which can break down biomass, in maize seed. By carefully designing the processing chain, from a single crop of maize we can deliver oil that can be turned into biodiesel, cellulose that can be used to make other biofuels, and fibre and protein which can be used as animal feed, as well, of course as the enzymes themselves," he reveals. "These multiple products offset the outlay on the enzyme purification process, meaning we can make enzymes far more cost-effectively than is achievable using traditional fermentation methods, a result which we can also see in a similar sugarcane processing project."
In the 1990s there was much interest in using plants to make both industrial enzymes and pharmaceuticals, but in the last five years such industrial enzyme developments have gone out of fashion, largely due to production costs that simply weren't viable, combined with public unease. Now Professor Nikolov's group have brought this technology back into the picture.
"The economic improvements that we have delivered to the processing pathway, combined with a greater public acceptance of transgenic plants, mean that we can now develop the full potential of this technology. This in turn will bring us a step closer to the vital challenge of generating cheap alternative fuels over the coming decades," he concludes.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
