Yeast fermentation: An optimized production of CO₂ over 24 hours with the Biogents BG-CO₂ Generator for professionals

With the BG-CO₂ Generator, Biogents provides an easy-to-use-set for the reliable production of CO₂ over a 24 hour period with yeast fermentation. With this set you can overcome the problems of logistics of gas cylinders and dry ice when using CO₂ for your mosquito monitoring traps.

Features of the BG-CO₂ Generator:

  • CO₂ production for 24 hours
  • Stable & reliable CO₂ output
  • Cost-effectiveness
  • Easy to procure ingredients
  • Easy to assemble and use
  • Re-usable set
  • Thermal control with BG-Pro bag
  • BG-CO₂ Powder as refill

The BG-CO₂ Generator includes a special BG-CO₂ Powder consisting of an optimised mixture of different yeast strains and nutrients, a mixing bag, a thermometer, a spoon, and an insulated bag. The set is re-usable and the BG-CO₂ Powder is available as a refill component. The only components you need to add are sugar and warm water.
The insulated BG-Pro carrying bag serves as a container for the mixing bag keeping the temperature stable and therefore the CO₂ production reliable through thermal control.

Biogents‘ specially formulated BG-CO₂ Powder

The key element of the BG-CO₂ Generator is the BG-CO₂ Powder which is an optimized formulation of various yeast strains and nutrients to provide the highest production of CO₂ over a 24 hour period. This optimized mixture was developed by Biogents to be used specifically for mosquito monitoring and the package (200 g) lasts for up to 10 monitoring sessions.

Performance of Biogents‘ CO₂ Powder

The CO₂ production of Biogents‘ optimised yeast powder was tested against other yeast strains over 24 hours. Result: The BG-CO₂ Powder shows the fastest start of CO₂ production and highest output over time in comparison to the other yeast strains.

The CO₂ production of Biogents‘ yeast powder is optimised for 24 hour monitoring and has the highest output within the first 14 hours.
