They frequently refer to the bioreactors as fermenters because they are mechanically quite similar which was my point. Also that 25m3 is in comparison to 200-1000m3 vessels used commercially. They also note sufficiently sterilizing a 200m3 vessel is viable, but due to various assumptions about cells used reach 25m3. However their analysis is frequently referring to mammalian cells while chicken is a commonly consumed meat source.

They address one of your criticisms right at the beginning: “The replacement of amino acid media with plant protein hydrolysates is discussed and requires further study.”

It’s a solid analysis in the short term, but optimizing cell lines can significantly change some of these numbers.
