This paper presents the investigation on biosynthesis of high-value-added amino acids and sugars labeleduniformly with stable isotope 13C by microalga Spirulina (Arthrospira) maxima in a parallelepiped photobioreactor.The kinetic data of both batch and continuous cultures with characterization of the amino acids and sugars areshown. The continuous culture without nutrients deficiency is for biosynthesis of amino acids, with tyrosine as oneof the principal constituents, and the batch culture with deficiency in nitrogen is for biosynthesis of labeled glucosethat is up to 64% versus dry mass of cells.
