Cost per kg of product
- Substrate (sugar price / yield)
- Downstream (price per kg broth / titer)
- Reactor (cost per m³ and h / overall productivity)
One batch, in hours
How it works
Cost per kg = sugar price ÷ yield + downstream cost per kg of broth × 1000 ÷ titer + reactor cost per m³ and hour ÷ overall productivity.
Overall productivity is titer ÷ (production time + turnaround), with production time = titer ÷ rate. So a higher titer at the same rate means a longer batch, and a long turnaround makes a slow process worse than its rate suggests.
Raising the yield is capped at the maximum theoretical yield, because no strain can convert more carbon than the stoichiometry allows. The default numbers are illustrative and are not data for any real process.
