“Biodiesel is an alternative energy source and a substitute for petroleum-based diesel fuel,” explains Professor Steinbüchel of the Westfälische Wilhelms-Universität in Münster. “A growing number of countries are already making biodiesel on a large scale, but the current method of production is still costly”.
“Biodiesel production depends on plant oils obtained from seeds of oilseed crops like rapeseed or soy”, explains Professor Steinbüchel. “However, production of plant oils has a huge demand of acreage which is one of the main factors limiting a more widespread use of biodiesel today. In addition, biodiesel production must compete with the production of food, which also raises some ethical concerns”.
Microdiesel, as the scientists have named it, is different from other production methods because it not only uses the same plant oils, but can also use readily available bulk plant materials or even recycled waste paper if engineering of the production strain is more advanced.
Also, it does not rely on the addition of toxic methanol from fossil resources, like many other biodiesels. The bacteria developed for use in the Microdiesel process make their own ethanol instead. This could help to keep the costs of production down and means that the fuel is made from 100% renewable resources.
“Due to the much lower price of the raw materials used in this new process, as well as their great abundance, the Microdiesel process can result in a more widespread production of biofuel at a competitive price in the future”, says Professor Steinbüchel.
There is a growing number of fuels used in cars and homes that are produced with the help of microbes. UK ministers are considering doubling the targets for the amount of biofuels sold in Britain by 2015.

New 3-D model predicts best planting practices for farmers

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
