Kuhner Solar web

The Kuhner energy is produced on the company’s roofs. Since May 2013 Kühner AG generates up to 64 kW on sunny days with more than 200 solar panels and avoids more than 54 tons of CO2 per year!

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.

From this new office we offer expanded hours of availability and access to Kuhner service for our East Coast customer base. Additionally, from this facility we will enjoy expanded time-zone overlap with our headquarters and factory in Basel, Switzerland – where 100% of our design, fabrication, assembly and Quality Control take place. Together we will continue to work with our Swiss office to provide the level of customer experience we expect for our valued customers.”

"Kuhner Shaker is excited to offer this new level of service and support to our North American customer base."

Brian Trippe comments, “Our immediate objective is to provide an elevated level of local contact for our existing customer relationships on the East Coast. Our customers deserve a fast response to their requests; this is the value of having a local office. Boston is a major biotechnology hub and being here are allows a quick, local response which extends all the way down the coast.

Forum Shaking Technology - answers to questions concerning shaken bioreactors

by Kuhner Shaker | Jul 29, 2014


Supported by four partner companies (EnzyScreen, Kuhner AG, PreSens and TPP Techno Plastic Products AG), "Forum Shaking Technology" began in 2008 to provide developers and users of shaken bioreactors with support and information.

The website offers help to anyone searching for more information on shaken bioreactors. It includes an FAQ section, a free scientific publication database which is constantly updated, newsletters on the most recent innovations in technology, and most important- Dr Shaker, the figurehead of the Forum Shaking Technology.

Dr Shaker answers any questions about shaken cultures - connecting users with specialists from academia and industry if necessary. Enquiries and user information are treated confidentially and questions are always forwarded anonymously.

Who is the person behind Dr Shaker? Britta Anderlei, a laboratory experienced micro-biologist. She created the forum website and continues to manage its content, keeping it up to date with the latest developments in the sector.

The four partner companies cover most sizes of shaken bioreactors, from microplates (Enzyscreen), small scale bioreactors (TPP) and online monitoring systems (PreSens), to shakers and very large vessels (Kuhner). Forum visitors benefit from their broad knowledge.

The Forum aims to address new topics, give impulses and create interest in different methods. The Forum also provides fundamental background information on shaking such as the important influence of shaking diameter or filling volume. Users are able to challenge their standard laboratory procedures and potentially improve their results.
