Influencing of Amino Acid Composition of Green Freshwater Algae and Cyanobacterium by Methods of Cultivation

Abstract

Aim: To determine and evaluate amino acid profiles in algal biomass of green freshwater microalgae Chlorella kessleri, Scenedesmus quadricauda and Chlorella sp. and blue-green micro-alga (cyanobacterium) Spirulina platensis cultivated by various methods. To perform the comparison of amino acid contents in algal biomass originated from cultivation methods. Material and Methods: Selected species of green freshwater micro-algae and blue-green microalgea were cultivated under the autotrophic cultivation in laboratory, in an outdoor open circulating cascade-type cultivation apparatus in a thin-layer, in a solar photobioreactor and under the heterotrophic cultivation regime in a fermenter.
