摘要： The invention provides a process of treating Rooibos plant material to obtain Rooibos tea extracts with improved extract yield and colour development. The process includes contacting Rooibos plant material with an effective amount of at least one exogenous enzyme under predetermined conditions thereby to obtain Rooibos tea extracts having improved extract yield and colour development. The enzyme is selected from pectinase, ferulic acid esterase, ß-glucanase, cellobiohydrolase, ß-xylanase and phenol oxidase and the Rooibos plant material is selected from green tea, fermented tea or spent tea.

摘要： 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.
