PROCESS FOR PRODUCING CONJUGATED LINOLENIC ACID FROM LINOLENIC ACID EMPLOYING BIFIDOBACTERIUM BREVE, BIFIDOBACTERIUM BIFIDUM, OR LACTOBACILLUS ORIS STRAINS

摘要

Method for preparing isomers of conjugated linolenic acid (CLNA) from linolenic acid (LNA) in a medium comprising at least the fat portion contained in a milk-based productor composition, in which at least one strain of a lactic acid bacteria or a bifidobacteria selected from the species of the group consisting of Bifidobacterium breve, Bifidobacterium bifidum and Lactobacillus oris is used. The invention also includes particular strains of all these species that allow performing the method in with high yields and conversion rates, as well as food products, nutritional compositions and pharmaceutical compositions containing them which are useful as anti-obesity agents and as immunomodulator agents.
