Abstract

Enzyme degrading rhamnogalacturonane II (RG-II) having an endo-.beta.-L-rhamnopyranosyl-(I.fwdarw.3')-D-apiofuranosyl hydrolase activity and/or an endo-.alpha.-L-fucopyranosyl-(I.fwdarw.4)-L-rhamnopyranosyl hydrolase activity. This enzyme can be produced by a microorganism, especially of the penicillium species, such as the branches 1-1577 and 1-1578 lodged with the CNCM. The RG-II can obtained from plant extracts by means of a method comprising a chromatography stage.
