Asterix Foods: Pioneering Plant Cell Culture for Bioactive Glycoproteins
Revolutionizing Protein Production
In the quest for sustainable alternatives to animal proteins, Asterix Foods is taking a bold step forward by leveraging plant cell culture technology. Unlike many startups that rely on precision fermentation using microbial hosts like yeast and fungi, Asterix argues that plant cell cultures can achieve these goals more efficiently and economically.
Understanding the Advantage of Plant Cells
Founder Dan Even shares with AgFunderNews that while traditional fermentation methods can handle simpler proteins, they struggle with complex glycoproteins essential in various industries. These glycoproteins, such as lactoferrin and ovomucoid, require precise glycosylations for proper function. Asterix aims to unlock potential in this ‘second wave’ of animal-free proteins using plant cells, which boast a glycosylation machinery similar to that of mammalian cells.
A Cheaper and More Efficient Production Process
Asterix has developed an innovative growing system that utilizes inexpensive plastic bags for cell culture. This method not only allows for rapid scaling but also proves to be more cost-effective compared to traditional stainless steel bioreactors. Even explains, “We’re talking about a few hundred dollars per bioreactor unit, compared to millions for microbial fermentation systems.” This affordability allows partnerships with companies to begin production with a minimal investment and quickly adapt to market demands.
Energy Efficiency and Operational Ease
While Asterix’s engineered plant cells have a longer doubling time of 10-15 hours, their ability to grow at room temperature translates to significant energy savings. The simple bioreactor design also requires fewer resources for monitoring and maintenance. “We can continuously run our processes, sterilizing infrequently, which minimizes downtime to about a month per year,” adds Even, contrasting the operating times of precision fermentation systems.
A Future-Focused Business Model
Asterix’s long-term goal is to license its patent-pending technology to various food and ingredient companies. By providing bioreactor systems and cell lines, they aim to integrate their process seamlessly into existing manufacturing operations worldwide. As for downstream processing, Asterix has simplified this aspect by creating a method that allows proteins to be secreted into the media, simplifying harvest and enhancing overall efficiency.
Conclusion: The Potential of Plant Cell Culture
As consumer demand for sustainable and animal-free proteins rises, Asterix Foods positions itself at the forefront of this evolution in food technology. With a clear focus on glycoproteins and an efficient production model, Asterix is not just imagining a better future but is already shaping it.
