How much protein fermentation can produce, how efficiently it can produce it, and what that protein ultimately costs all depend in part on the performance of the production strain. 

Traditional strain-development methods can only evaluate a limited number of variants at a time. That means teams are often stuck optimizing the strains they can practically test, while rarer, higher-performing strains that boost economics may never be found. 

Saku Biosciences screens millions of variants in bioreactors to search larger cell populations and identify strains that produce more protein, earlier in the development process—saving time, cutting costs, and scaling production capacity
