THE AMINO ACIDS COMPOSITION OF THE BLUE-GREEN ALGA NOSTOC GELATINOSUM (SCHOUSB) ELENK

This article presents the amino acid content of the blue-green alga Nostoc gelatinosum (Schousb) Elenk. collected from the Drew nutritive medium. From the essential amino group in Nostoc gelatinosum (Schousb) Elenk. biomass, major amounts are contained leucine (2,142 ± 0,06 mg/100 mg), threonine (1,188 ± 0,02 mg/100 mg) and valine (1,085 ± 0,03 mg/100 mg). From nonessential amino acids predominates aspartic acid (4,523 ± 0,11 mg/100 mg) and glutamic acid (2,774 ± 0.07 mg/100 mg). The alga Nostoc gelatinosum (Schousb) Elenk. has a high content of amino acids and can serve as a source for vast areas of application. Keywords: Nostoc gelatinosum, biologically active substances, essential amino acids, nonessential amino acids.
