Large-scale production of yak (Bos grunniens) chymosin A in Pichia pastoris.

Cross-Sectional Study

In Vitro

2019 Feb

The study tested whether adding sugar molecules to a lab-made milk-clotting enzyme from yaks made a difference in how well it worked or how much was made, and found it didn’t matter at small scale.
