Abstract
A method for producing pyruvic acid from polysaccharide alginic acid that is contained in large amounts in brown algae using the ability to assimilate alginic acid possessed by a lactate-dehydrogenase-gene-deficient Sphingomonas sp. A1 strain (ldh strain) is provided. The method for producing pyruvic acid comprises culturing the lactate-dehydrogenase-gene-deficient Sphingomonas sp. A1 strain (ldh strain) in a medium containing alginic acid, and causing the strain to produce pyruvic acid from alginic acid and then to secrete pyruvic acid into the medium.
