A kappa-carrageenase was isolated from the cell-free medium of cultured Pseudomonas carrageenovora. From dodecylsulphate/polyacrylamide gel electrophoresis, a single protein (identified as the kappa-carrageenase) was detected in the medium. Activity against nominal carrageenan types and inspection of the products indicate the
