High biomass producers and promising candidates for biodiesel production from microalgae collection IBASU-A(Ukraine)

A comparative study was carried out on the growth characteristics of 33 strains of 12 species belonging to genera Acutodesmus (7), Botryococcus (1), Chlorella (5), Chloroidium (2), Desmodesmus (8), Euglena (2), Monoraphidium (2), and Parachlorella (6) from the Microalgae Culture Collection of the Institute of Botany, NAS of Ukraine (IBASU-A). All high biomass-producing strains considered as promising candidates for biofuel production demonstrated active growth (high maximum cell concentration, specific growth rate and productivity). The most promising strains included Acutodesmus dimorphus IBASU-A 251, 252, Desmodesmus magnus IBASU-A 401, D. multivariabilis var. turskensis IBASU-A 398, Chlorella vulgaris IBASU-A 189, 192, and Parachlorella kessleri IBASU-A 444. Their productivity varied from 0.58 g d.w. l^-1 to 1.6 g d.w. l^-1 per day. In general, the cultivation of these strains is considered both as a potential bioresource of feedstock for biodiesel production and other industrial demands.
