“…Our experience in large-scale microalgae cultivation provides the basis of organizing industrial production in the Russian Federation [3,10]. In connection with the above conditions of microalgae cultivation the task of evaluating territories in terms of their suitability for large-scale microalgae production can be formulated.…”

Abstract. Microalgae is a perspective feedstock for producing a wide variety of biofuels and co-products with high added value. An alternative to the traditional technology of biodiesel from algae by the transesterification is the technology of hydrothermal liquefaction (HTL). The article presents the results of promising strains screening and directed cultivation of microalgae for the processing by means of variety of technologies and production of valuable co-products. An algorithm for selecting suitable areas for industrial plantations of algae is presented.

“…Microalgae are the most convenient for an accelarated biomass recovery due to the conversion of solar energy, and they serve as a promising nontraditional raw material for bioener getics, including energy generation and motor fuel production (Chernova et al, 2014). It was revealed that marine and geothermal waters in the culture medium with Nannochloropsis salina microalgae, with the additional introduction of mineral composition, promote physiological activity and a reduction in the growth period of the population, which influenced the dynamics of biomass accumulation and lipid synthesis (Magomedov et al, 2013).…”

The current state and prospects of the development of ground waters in Dagestan have been reviewed. A complex theoretical and experimental study of the mechanisms by which biologically active sub stances of geothermal waters influence yeast metabolism has served as the basis for the development of bio technologies to produce biochemically active Saccharomyces strains, bakery products, and ethanol. The application of new technology products in various industries opens up possibilities for creating high perfor mance agroindustrial enterprises in both Dagestan and other regions of Russia with geothermal resources.

Yields of liquid products (bio-oil and residual organics in aqueous solution) of hydrothermal liquefaction (at 300℃ and 60 min) of own cultivated Arthrospira platensis using different solvents have been determined. Nonpolar hexane, moderately polar dichloromethane, and relatively more polar acetonitrile have been used. High-resolution mass spectrometry based on linear quadrupole ion trap and Fourier transform mass spectrometer (LTQ FT) has been used for liquid sample characterization. Concentration of bio-oil in a unit of solvent volume after solvent extraction took the following arrangement: acetonitrile > dichloromethane > hexane. Concentration of residual organics in a unit of aqueous solution after solvent extraction took the following arrangement: hexane >dichloromethane > acetonitrile. Yield of total organics was arranged as follows: hexane > dichloromethane > acetonitrile. Content of carbon in bio-oil was increased and the content of oxygen was decreased with the increasing of solvent polarity. From mass spectrometric analysis it was established that in the positive electrospray ionization (ESI) mode the compounds containing two nitrogen atoms dominate and the considerable portion of the compounds containing single nitrogen atom are also presented for both bio-oil and residual organics samples. In the negative ESI mode the compounds containing four oxygen atoms dominated except bio-oil obtained using hexane where the compounds containing two oxygen atoms dominated. Bio-oil fraction had highly saturated compounds with low double bond equivalent values while the compounds of the residual organics fraction had large double bond equivalent values.
