The most common way to produce enzymes is through submerged microbial fermentation. However, by returning to a much older technology, solid-state fermentation, enzymes can be produced with a broader range of activities.

Enzymes are naturally occurring proteins, which are degraded in the intestine and consist of little more than amino acids. International legislation takes this into account, but as new and better enzymes are developed, countries need to have the syst...

Biotechnology has vastly increased the tools available for producing proteins. In particular, plants may be about to revolutionise the manufacture of feed enzymes. They can be produced at low cost and with immense stability, so storage and processing...

Exogenous enzymes have become a popular tool for releasing nutrients from feed, and there is much scientific literature supporting their use. However, are non-starch polysaccharidedegrading enzymes being exploited to their full potential? Scientists...

Phytomolecules added to feed may not produce their effects on growth and productivity via the same mode of action as once thought. Research has allowed us to revise our thinking, and to take a more integrated approach to the use of plant extracts, c...
