Day after day, legions of microorganisms work to produce energy from waste in biogas plants. Researchers from Bielefeld University’s Center for Biotechnology (CeBiTec) are taking a close look to find out which microbes do the best job. They are analysing the entire ge-netic information of the microbial communities in selected biogas plants up and down Germany.
Stained, they fluoresce under the microscope: a wide variety of microbes can be seen in a sample taken from a biogas plant. Researchers at Bielefeld University want to find out which ones do their job best.
From the beginning of 2013, the Californian Joint Genome Institute will undertake the sequencing required. The biocomputational analysis will be performed at CeBiTec. Not an easy task, since the data will be supplied in billions of fragments stemming in turn from hundreds of organisms. Piecing together this huge jigsaw puzzle will be painstaking work.
In Germany, there are more than 7,000 biogas plants which can supply over six million households with power. The plants are filled mostly with plant biomass like maize silage but also with agricultural waste materials like liquid manure and chicken manure. One of the key research questions is how the production of biogas can be optimised. For this reason, Bielefeld scientists Dr Alexander Sczyrba, Dr Andreas Schlüter, Dr Alexander Goesmann, Professor Dr Jens Stoye und Professor Dr Alfred Pühler want to know what microbes are responsible for the decomposition of biomass - and which of them do it best. “We are interested in discovering the microbiology that is really behind the processes going on in a biogas plant; what microor-ganisms play which role at which stage,” explains Andreas Schlüter, whose research at CeBiTec is in the field of biogas production.
The researchers have scheduled roughly two years for their project, in which also Bielefeld doctoral students of the Graduate Cluster in Industrial Biotechnology (CLIB) are involved. At the end, they hope to have discovered the optimal microbial community for biogas plants - and thus be in a position to make this process of generating energy even more efficient.Background

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
