FRINGS specializes in those areas of special yeast fermentations that require particular attention to plant-specific, sterile or procedural aspects.

These groups of yeast processes of this category comprise e.g.:

• Cultivation / propagation of brewery yeasts (culturing or assimilation yeast)
• production of "savoury" yeasts having specific sensoric characteristics
• cultivation of carotinoid producing yeasts (e.g. Phaffia rhodozyma)
• special yeast fermentations for the production of starter cultures
• fermentation of special yeasts as a catalyst for biotransformations
• processes with methylotrophic yeasts (e.g. Pichia pastoris or Hansenula polymorpha) for the production of active agents and enzymes
• ...

Based on a detailed analysis of the specific requirements of the fermentation,
FRINGS supplies customized fermentation systems and further equipment,
inter alia:

• Yeast fermenters of the PRORACT B, P and G series with varying fermenter equipment and in different sterile designs
  from 500 mL to 250 m³
• high-performance aeration systems of FRIBORATOR and TRG types up to 450 kW drive performance
• mechanical foam centrifuges of FOAMEX build, designed to make the use of anti-foam agents superfluous
• equipment for up- and downstream
• process measurement and control devices for process control and regulation

Technology package units and complete plants for baker's yeast production for the bakery industry as well as innovative technologies for bioethanol production with yeasts are supplied by our cooperation partner DESMET BALLESTRA ETHANOL (http://www.desmetballestra.com).
Here, too, our high-performance aeration systems are often applied.
