THE NUTRITIONAL POTENTIAL OF ALGAL BIOMASS OF NOSTOC FLAGELLIFORME (BERK ET CURT) ELENK.

In this study is presented the biochemical components of algal biomass Nostoc flagelliforme (Berk et Curt) Elenk. cultivated in laboratory conditions in Z-8 medium. The algal biomass has the following chemical content: 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, Mg2+ – 5,40 g/kg, Ca2+ – 7,94 g/kg. The highest amount of amino acids are specific for: glutamic acid – 3,8012 mg/100 mg, aspartic acid – 2,7838 mg/100 mg, leucine – 2,4651 mg/100 mg, alanine – 2,3513 mg/100 mg. According to these results the bluegreen alga Nostoc flagelliforme can be considered an important potential source of nutritional supplements. Keywords: Nostoc flagelliforme, biochemical composition, nutrient medium, nutrition.
