Your Kuhner shaker team

Kuhner shaker also supports young talents with their research projects

by Kuhner Shaker | Sep 26, 2014


Kuhner Shaker provides an incubator shaker to the association “Forscher/innen der Region” (Researchers of the region ) to support their projects. The association based in Gegenbach, Germany is dedicated to support and promote young people in the academic disciplines MINT (mathematics, information sciences, natural sciences and technology). Among others talents are supported and participations on regional and nationwide competitions are enabled.  

The shaker is first used for the following two microbiological projects:

  • Optimization of the PHB synthesis of Paracoccus denitrificans to alternative production of biopolymers, which the research team with Daniel Heid works towards the BioValley College Award in Basel
  • Thiothrix sp. –investigation of sulfur-reducing bacteria for sensor-controlled biogas desulphurisation, which participates in the EUCYS competition in Warsaw.

Daniel Heid and all participants present their project in our KuhnerBlog:

Optimization of the PHB synthesis of Paracoccus denitrificans to alternative production of biopolymers

Even though we all contributed just a little, big amounts of plastic waste have been cumulated in the last few decades which lead to a serious global-biological problem. Since synthetic materials only degrade in several thousand years, new biological alternatives for PP, PE and Co. are searched for. Polyhydroxybutyrate is one of this promising biopolymer.

In addition to the biodegradability, PHB has also no disadvantages against synthetic plastics in function and options of use.

However, due to the high production costs it isn’t an economic alternative for the industry. In this project we analyse how to increase the efficiency of the production to gain a profitable biopolymer.

By optimizing the culture medium and especially the addition of glycerol, we were able to increase the production of PHB with the bacterial strain P.denitrificans. Our strategy is to couple the degradation of waste fats and oils (gaining glycerol as a cheap by-product) and the actual process of PHB synthesis to create a cost-effective way of producing PHB.


Kuhner Shaker wishes the young team great success and looks forward getting more reports in future.
