Binder's new BF 115 fermentation bio-reactor can be used for laboratory researches as well as for production processes. Binders claims the unit to be well suited for gentle incubation applications. According to company officials, the reactor provides a high throughput even when fully loaded. Dynamic features help to keep the required temperatures stable with homogeneous distribution.

Dr.-Ing. Konrad Koch, who uses a BF 115 unit in his researches on biogas production processes at the Bavarian Institute for Agricultural Engineering, determines the improvement of fermentation processes as a crucial factor for efficient energy production from renewable resources. According to Koch, understanding the complex ongoing processes and the microorganisms involved with the aim of maximizing gas yield is the top priority. Analysing the interaction between different groups of microorganisms is, nevertheless, a difficult task: "It is important to understand which bacteria take over at which point in the degradation processes," explains Koch. "Only after we understand these processes and relationships can we identify weaknesses in the processes and ensure sustainable improvement."
