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.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
