DESCRIZIONE
The invention describes a new Aspergillus carneus fungus strain, designated Aspergillus carneus (van Tiegham) Blockwitz (CBS 116150). The fungus strain produces a number of exogenous fibrolytic enzymes which are capable of increasing cell wall degradation, and thereby digestibility, of an animal feed, such as wheat straw, ruminant feed, fish feed or poultry feed. Products containing these enzymes, such as a culture supernatant, a feed additive and an animal feed, are also described.
