Аннотация:The search for alternatives to hydrocarbon fuels remains an actual task. Microalgae(MA) as raw material for the production of biofuel remain an urgent object of research amongother types of biomass, and the cultivation of MA is constantly growing. One of the promisingtechnologies for biofuel production from MA is hydrothermal liquefaction (HTL) that allowsprocessing wet biomass and turning all carbon-containing components (lipids, carbohydrates,proteins) into fuel. However, the hydrothermal liquefaction process leads to the formation of asignificant amount of the aqueous phase, which is a by-product with low energy value and alsoneeds to be processed. It is important to consider the possibility of using the aqueous phaseafter HTL, as well as municipal wastewater, for the cultivation of MA in combination with theproduction of biofuels. The MA strains capable to grow in a dilute aqueous phase after HTL(Galdieria sulphuraria rsemsu G-1, Chlorella vulgaris rsemsu Chv-20/11-Ps, Arthrospiraplatensis rsemsu Bios) and in wastewater (Arthrospira platensis rsemsu Bios, Chlorellaellipsoidea rsemsu Chl-el) were experimentally selected from collection of RSE Laboratory atLMSU. The article is devoted to the experimental study of the degree of nutrients utilization byMA from wastewater and an HTL-aqueous phase.
