In prezentul studiu este prezentată componenţa biochimică a biomasei algei cianofite Nostoc flagelliforme (Berk et Curt) Elenk. cultivatăîn condiţii de laborator pe mediul mineral Z-8. Biomasa algei conţine: Mn – 683,9 mg/kg, Zn – 131,5 mg/kg, Pb – <10 mg/kg, Fe – 1,09 g/kg, Na+ – 2,10 g/kg, K+ – 8,01 g/kg, Mg 2+ – 5,40 g/kg, Ca2+
– 7,94 g/kg. În componenţa aminoacizilor predomină: acidul glutamic – 3,8012 mg/100 mg, acidul aspartic – 2,7838 mg/100 mg,
leucina – 2,4651 mg/100 mg, alanina – 2,3513 mg/100 mg. Conform acestor rezultate, biomasa algei cianofite Nostoc flagelliforme
poate fi utilizată ca sursă importantă de suplimente alimentare.
