Robert Linhardt of Rensselaer Polytechnic Institute sequences bikunin; findings published in Nature Chemical Biology DNA and protein sequencing have forever transformed science, medicine, and society. Understanding the structure of these complex biomolecules has revolutionized drug development, medical diagnostics, forensic science, and our understanding of evolution and development. But, one major molecule in the biological triumvirate has remained largely uncharted: carbohydrate...

Turning Up The Heat On Biomass Pretreatment Processes
2011-10-03 04:43:00

The nation's Renewable Fuels Standard calls for annual production of 36 billion gallons of biofuel by 2022. One of the biggest hurdles to achieving this goal lies in optimizing the multistep process involved in breaking down plant biomass and then converting it into fermentable sugars that can be refined into fuel for our transportation needs. To overcome this challenge, the U.S. Department of Energy supports several projects focused on identifying enzymes from fungi and microbes such as...

Water acts as an 'adhesive' in biological enzyme substrate compounds In biologically active enzyme substrate compounds, as can be found in medicines, water plays a more decisive role than has been imagined up to now. The surrounding water acts like an "adhesive", in order to keep the substrate at the right place on an enzyme. For this, the dynamism of the water is retarded. Scientists at the RUB under Prof. Dr. Martina Havenith (Physical Chemistry) in close cooperation with the group of...

Professor André Hudson's research could advance algaecide development Algaecide is no crime. Consider that some strains of algae produce toxins lethal to wildlife, fish and plants. Even the less harmful varieties suck oxygen out of water, suffocating living creatures in lakes, ponds, pools and aquariums. Recent algal blooms in the Great Lakes, for instance, threaten critical ecosystems. Rochester Institute of Technology scientist André Hudson and colleagues...

Feedback mechanism coordinates cellular respiration and the degradation of free oxygen radicals Oxygen-consuming organisms obtain energy through cellular respiration, which is the transformation of carbohydrates and oxygen into carbon dioxide and water. This process also produces toxic oxygen radicals which must be decomposed immediately, as they would otherwise cause damage to cells. Scientists from the Max Planck Institute for Molecular Genetics in Berlin have now discovered a mechanism,...

Max Planck researchers analyze the structure of an iron storage protein Microbes are omnipresent on earth. They are found as free-living microorganisms as well as in communities with other higher organisms. Thanks to modern biological techniques we are now able to address the complex communities and study the role of individual microorganisms and enzymes in more detail. Microbacterium arborescens is a bacterium, which can be found in the guts of herbivorous caterpillars. The Department...

Scientists from the University of York have played a pivotal role in a discovery which could finally unlock the full potential of waste plant matter to replace oil as a fuel source. Professor Paul Walton and Professor Gideon Davies, of the University's Department of Chemistry, were part of an international team that has found a method to overcome the chemical intractability of cellulose, thus allowing it to be converted efficiently into bioethanol. Working with scientists in Novozymes...


Word of the Day
jument
  • A beast of burden; also, a beast in general.
'Jument' ultimately comes from the Latin 'jugum,' yoke.
