CONTROLLED PRODUCTION AND DELIVERY OF BIOLOGICALLY ACTIVE AGENTS BY GUT BACTERIA

摘要

The invention provides gut commensal bacteria that have been modified to express one or more biologically active polypeptides or protiens, the bacteria includes a promoter, such as a xylanase promoter, which is induced in response to the presence of xylan in the diet and which regulates the expression of the biologically active polypeptide or protien.
