The description linked talks about a distinct sterilization phase, where hot steam is passed trough the installation prior to use. It seems exactly like the type of situation described in the article, where small welding gaps allow bacteria to stay alive - I would imagine, especially if the surrounding metal has enough thermal mass. My suggestion was a bit more nuanced, heat the very body of the reactor + reaction medium; but I could be venting hot air.
Nonetheless, it's not a fundamental, thermodynamic limit, it's not like bacteria spontaneously materialize inside vats above a certain volume. It's a technical problem to solve, it seems solvable and once you solve it, all 100 ton reactors can use that design.
