Abstract
The study is devoted to investigation of the possibility of green microalga Desmodesmus armatus cultivation in mixotrophic conditions. Microalgae were cultivated on the waste water from RAS. To create mixotrophic conditions in the nutrient medium, glucose was added in the amount of 0.5, 2 and 4 g/l. Cultivation was carried out in a climatic room with a 16-hour photoperiod for 21 days. The rate of biomass growth was analyzed in the cultivation dynamics with presence of glucose in a nutrient medium. In the obtained biomass, the indicators of crop productivity were analyzed – the amount of protein, lipids and photosynthetic pigments. It is noted that the introduction of glucose in an amount of 0.5 g/l allows to increase in biomass yield by six times. It is established that in all variants of the experiment the amount of protein remains unchanged, however, the amount of lipids, chlorophyll a and carotenoids increases. The optimum concentration of glucose for the growth of Desmodesmus armatus in mixotrophic conditions is the amount of 0.5 g/l of nutrient medium.
