DNA fragment of genomic origin coding for at least one enzyme involved in the biosynthesis of an EPS, and capable, following the transformation of a lactic bacteria, of restoring the production of an EPS in the said bacterium not initially producing any EPS, or of modifying the structure of the EPS initially produced by the said bacterium. Proteins of the Streptococcus thermophilus strain CNCM I-1590 encoded by the chromosome and which are involved in the biosynthesis of the EPS having the composition Glc:Gal:GalNac=1:2:1. Method for the manufacture of a new EPS, in which a DNA fragment coding partially or totally for at least one enzyme involved in the biosynthesis of an EPS is cloned into a vector, lactic bacteria producing another EPS are trans- formed with the recombinant vector, and a lactic bacterium producing a new EPS is then selected.
