Abstract
Abstract A search for strains capable of the simultaneous production of high amounts of several biologically valuable compounds and/or high biomass productivity has been carried out. The growth characteristics and biochemical composition of 12 microalgal and cyanobacterial strains from the IPPAS Collection were studied at the exponential and stationary growth phases. All of the strains had high growth rates (a doubling time of 6–22 h). The strains Cyanobacterium sp. IPPAS B-1200, Chlorella sp. IPPAS C-1210, Nannochloris sp. IPPAS C-1509, Cyanidium caldarium IPPAS P-510, and Vischeria sp. IPPAS H-242 demonstrated the highest biotechnological potential and can be used for the production of various types of biofuel, pigments, and feed and food additives, including those with a high content of eicosapentaenoic acid (20 : 5 Δ5, 8,11, 14, 17).
