Algae biomass is considered as an alternative raw material for the production of biofuels. The search for new types of raw materials, including high-energy types of microalgae, remains relevant, since the share of motor fuels in the structure of the global fuel and energy balance remains consistently high (about 35%), and the price of oil is characterized by high volatility. The authors have considered the advantages of microalgae as sources of raw materials for fuel production. Biochemical and thermochemical conversion are proposed as technologies for their processing. This paper presents the results of the study of the pyrolysis of the biomass of clonal culture of blue-green microalgae / cyanobacteriumArthrospira platensis rsemsu 1/02-Pfrom the collection of the Research Laboratory of Renewable Energy Sources of the Lomonosov Moscow State University. An experiment to study the process of pyrolysis of microalgae biomass was carried out at the experimental facility of the Institute of High Temperatures RAS in pure nitrogen grade 6.0 to create an oxygen-free environment with a linear heating rate of 10 ºС / min from room temperature to 1000 ºС. The whole process of pyrolysis proceeded in the field of endothermy. The specific amounts of solid residue, pyrolysis liquid and gaseous products were experimentally determined. As a result of the pyrolysis of microalgae biomass weighing 15 g, the following products were obtained: 1) coal has the mass of the solid residue is 2.68 g, or 17.7% of the initial mass of the microalgae (while 9.3% of the initial mass of the microalgae remained in the reactor); 2) pyrolysis liquid – weight 3.3 g, or 21.9% of the initial weight; 3) non-condensable pyrolysis gases – weight 1.15 l. The specific volumetric gas yield (the amount of gas released from 1 kg of the starting material) was 0.076 Nm3/ kg. The analysis of the composition and specific volume yield of non-condensable pyrolysis gases formed in the process of pyrolysis, depending on temperature. It is shown that with increasing temperature, the proportion of highcalorie components of the gas mixture (hydrogen, methane and carbon monoxide) increases. The calorific value of the mixture of these gases has been estimated.

The application of a path method allowing the simulation of the process of semi-mark system operation is considered. There is shown a sample of the technological complex during the operation of which various failures are possible. The simulation of the technological complex taking into account depreciating failures is carried out; the accuracy of the path method is confirmed.

The model of the placental barrier based on the human choriocarcinoma cell line BeWo b30 allows studying the effect of hypoxia on trophoblast cells. The effect of the oxyquinoline derivative inhibiting HIF-prolyl hydroxylases was studied on this model. Inhibition of these enzymes leads to an increase in the HIF-1α subunit in the cytoplasm, mimicking the cell response to hypoxia. Incubation of the cells with the drug at a concentration of 10 uM for 24 h did not affect the paracellular transport, but reduced the transport of glucose through the cell barrier. The transcriptome analysis after the exposure with oxyquinoline derivative revealed a decreased expression of the KIAA1217 gene and its intronic gene MIR603, which encodes microRNA hsa-miR-603. The expression of the target gene of this miRNA, CCND1 encoding cyclin D1, after oxyquinoline derivative exposition increased significantly, which may indicate a potential microRNA-mRNA regulatory mechanism in the response of trophoblast cells to hypoxia. BeWo b30, placenta, hypoxia, oxyquinoline, barrier, microRNA, cyclin The study was performed with the equipment of the «Postgenomic and Metabolomic Methods of Study in Molecular Biology» Common Use Center (BioClinicum Scientific and Technical Center). The study was supported by the Ministry of Education and Science of the Russian Federation in the framework of the Federal Targeted Program for Research and Development in Priority Areas of Advancement of the Russian Scientific and Technological Complex for 2014-2020 (Project no. RFMEFI58817X0007).
