Fermentation is the gateway to more sustainable food and feed ingredients
Cost Effective
Our process delivers dependable scalable supply at a fraction of photobioreactor and open-pond production costs.
Resource Efficient and Sustainable
Our natural astaxanthin is made using one-tenth of the energy, water and land compared to standard technologies.
Only Kuehnle AgroSystems produces affordable natural astaxanthin from Haematococcus by dark fermentation. Our patented fermentation process, combined with our patented all-natural algal strains, is very fast, high yielding, and extremely economical. We utilize conventional fermentation vessels for minimal water and land use with maximal purity and control.
Our process enables much greater output volumes at a significantly lower cost than light-dependent algae production methods, to better respond to the rapidly expanding needs of consumers and the market
