cellulase

The researchers specifically studied the effect of a fungal cellulase enzyme called Cel7A.

To slow down the ripening process at home, you can just toss it in the fridge, delaying its production of cellulase.

In fact, T. reesei has a long history of safe use in industrial-scale production of carbohydrase enzymes, such as cellulase, which plays an important role in fermentation processes during winemaking.

Instead, he went online and bought a bottle of cellulase—the enzyme that rumen bacteria use to break down grass in the first place.

He would use cellulase in his artificial goat rumen.
