Biosynthesis of C-13-labeled amino acids and sugars by Spirulina (Arthrospira) maxima in a parallelepiped photobioreactor
This paper presents the investigation on biosynthesis of high-value-added amino acids and sugars labeled uniformly with stable isotope C-13 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 are shown. The continuous culture without nutrients deficiency is for biosynthesis of amino acids, with tyrosine as one of the principal constituents, and the batch culture with deficiency in nitrogen is for biosynthesis of labeled glucose that is up to 64% versus dry mass of cells.
