sugar beets

Sugar is not only a widely used food ingredient but can also be used as possible starting point for high-added-value products. The European research consortium of CARBAFIN explores different ways to make use of sugar beet biomass: the sugar components glucose and fructose are starting points for the production of important ingredients for not only food/feed but also cosmetics. Besides, fructose can be further converted to a platform chemical, which is applied to the production of bioplastics, biofuels or biopolymers, as well as resins. In other words, CARBAFIN people sweeten our lives!

Microorganisms play a crucial role for the health and well-being of higher organisms. Host-specific microbial communities of varying complexity form the so-called microbiota. It can consist of several thousand microbial species and includes bacteria, archaea and fungi. These microorganisms exchange a plethora of metabolites with their hosts and can modulate their functioning. Such interactions equally affect humans, animals and plants. This provides us with novel strategies to counteract various diseases and increase the resistance of higher organisms towards abiotic and biotic stresses by modulating the microbiota.


Enzymes are the tiny helpers of industrial biotechnology. Despite their microscopic size, they need to be tough and diligent because we want them to catalyze a broad range of reactions, ideally with the speed of light for ever after. In reality, however, many enzymes are like sensitive creatures, who need most careful attention and special treats to get their nicest behavior. Otherwise they might fade away like a tender flower in the blinking sun… and send the biotechnologists into terrible trouble. One strategy to find frugal enzymes is to look at thermophilic organisms. They sometimes harbor a treasure of more stable proteins because they are used to withstand somewhat unfriendly conditions such as high temperatures.


Fungi are ubiquitous organisms which have made a beneficial contribution to human development. This association dates back to 3000 B.C. when it is believed that for the first time, Egyptians used yeast for baking bread and brewing beer. Later with the discovery of penicillin from Penicillium chrysogenum, fungal antibiotics gained widespread use in treatment of infections. In the research field too, fungi serve as a model for genetics and cell biology. Filamentous fungi are known for secreting huge amounts of secondary metabolites like enzymes, organic acids, cyclosporins, and steroids. These valuable compounds have vast applications in several industries such as food, beverages, textiles, and pharmaceuticals. A well-known filamentous fungi is Aspergillus niger, an industrial workhorse for production of high titers of organic acids and enzymes.


The mankind flies to the moon, explores the universe – but still on earth there is much more unexplored matter than we are aware of. Bioprospecting is a discipline, where new products and processes are discovered based on natural resources. The big ideas and innovations for industrial processes are right in front of us – we just have to observe nature and – which is the difficulty – recognize them.

Among numerous carbon-carbon coupling reactions in organic synthesis, the Friedel-Crafts acylation enables the direct connection of aromatic compounds with carbonyl moieties. It is therefore one of the most popular chemical transformations and extensively used. The resulting products- aromatic ketones- are valuable building blocks and relevant to a range of industrial sectors, including the pharmaceutical, biotechnological and fine chemical industry. ACIB pioneers in developing a biocatalytic equivalent for this fundamental reaction, thereby exploiting a so-far little investigated cofactor-independent acyltransferase. But why considering enzymes to do this reaction?

In the past years the advent of microbiome research was facilitated by a tremendous decrease in DNA sequencing costs. The progression of sequencing technology and the growing demand for large datasets (beyond the size of the human genome) enabled this favorable progress, which even surpassed Moore’s Law. There are various technologies that benefited from these developments and many of them have a set position in modern laboratories.

Although we live in a world that is more developed than ever, toxins are omnipresent in our environment. During evolution, the human bodies developed ways to cope with many harmful compounds; most of them are degraded enzymatically. A project at the Austrian Centre of Industrial Biotechnology (acib) revealed new insights into life saving processes – especially into the enzymatic detoxification by a special class of enzymes called flavin containing monooxygenases (FMO).
