Materials and chemicals

Biomass can be used to produce chemicals, fibres, pigments and plastics. These products are either identical to their petroleum-based counterparts or have completely new properties. Biorefineries will play a key role in the transition to a bioeconomy. There is great expectation placed on the potential ability to convert the countless carbon compounds in biomass into chemicals and material components.

    Most of what is easily accessible has in principle already been discovered said Dr. Ivan Berg from the University of Freiburg explaining why he is investigating the metabolic pathways in extremophilic microorganisms. The researcher and his team are interested in the biochemistry of organisms living in hot volcanic springs and the Dead Sea. Examples of this are two metabolic pathways which the researchers from Freiburg discovered in organisms belonging to the Crenarchaeota. The bacteria use the pathways to assimilate atmospheric carbon dioxide without the risk of poisoning themselves with the breakdown products arising at high temperatures. What can industry learn from extremophilic bacteria? What are the advantages and disadvantages for laboratory applications? And what can we learn from them about evolution on Earth?

    The 2nd Laupheimer Zelltage conference organized by Rentschler Biotechnologie GmbH in Laupheim on 11th and 12th June 2012 focused on “Bioprocess light”. Twelve experts from applied research institutions and biotech companies from Germany and abroad provided the 200 or so guests with information on how modern bioproduction methods can be made simpler, more robust, cheaper, more reliable and hence more competitive.

    More than 50 researchers, designers, producers and users active in the fibre and textile industries came to Stuttgart on 3rd July 2012 to participate in the first “textile bio-based materials design challenge” (tbdc) workshop. The participants used the interdisciplinary environment to develop project ideas, exchange information and experiences and make new contacts.

    In his Konstanz-based Vegafood project office Dr. Peter May is focused on sustainable breeding of crayfish with the aim of advancing industrial scale chitin research. European crayfish shed their skin several times a year providing research institutions and chitin product manufacturers with access to crustacean carapaces.

    In view of the changing climate and the finiteness of fossil resources, research into renewable energies is gaining in importance. One of the things that researchers have been looking into for quite some time is different possibilities to use organic wastewater compounds as sustainable energy sources. Carsten Meyer from the University of Stuttgart works on the generation of alternative energy sources. Together with his team of researchers, Meyer was involved in a recently finished project that looked into the biological production of hydrogen from wastewater and sewage sludge.

    Microorganisms and sensitive cells that are grown in bioreactors need a well-regulated environment and a food supply in order to do what they are supposed to do: grow and produce biomass and metabolites. Many fermenters are equipped with sensors that continuously measure critical bioprocess parameters, including temperature, pH value and oxygen. Online glucose and ethanol sensors are not yet used in regulated bioreactors, even though they would make the bioprocess much quicker and more economical.

    An ever-growing number of genomes of soil bacteria of the genus Streptomyces are being sequenced. Using a method known as “genome mining”, researchers at the University of Tübingen are working on the identification of gene clusters that have the potential to be used in industrial biotechnology for the production of new antibiotics and other pharmaceutically active substances. To achieve this, the biosynthesis gene clusters are integrated into special production strains where they are optimized.

    Researchers led by Prof. Dr. Jan C. Behrends and Dr. Gerhard Baaken from the University of Freiburg have developed a chip the size of a fingertip containing biological nanopores that determine molecule mass with great precision. Developing this new system which is a combination of biological and micro-technical components involved a great deal of technical skill. The system has the same level of sensitivity as a chromatography device but is much easier to handle and is also cheaper than the large devices. The chip has also the potential to be used for sequencing genes and for analysing other molecule classes.
