“…The potential impacts of using biomass for vehicle fuel production on the environment and human health are subject of ongoing research; a large number of LCA studies for a lot of different feedstocks and fuels used in passenger vehicles has recently been published, e.g. in [25][26][27][28][29][30][31][32][33][34][35], showing large variations in terms of LCA results. Due to the intrinsic complexity in the LCA of biofuel chains with issues ranging from location specific aspects such as specific crop yields and water scarcity to controversial topics such as indirect land use as well as interaction with food markets, we consider a selection of ''representative'' biofuel chains for comparative use as impractical and therefore these fuels as being out of scope of our current assessment.…”

“…Microalgae have many characteristics, for example, large biomass, environmental adaptability, short growth cycle, as well as being photosynthetically efficient with oil productivity rates higher than that of other oil crops . Moreover, photosynthetic microalgae can capture CO 2 directly as bio‐fuel and they can be modified in terms of their oil‐storing capabilities or ability to synthesize various compounds, such as unsaturated fatty acids, proteins, polysaccharides, lipids and pigments, vitamins . Theoretically, the production of one ton of microalgae biomass will capture 1.83 tons of CO 2 as the carbon content of microalgae is approximately 40–50% of the total dry weight .…”

The aim was to study the effect of artificially constructed consortia of microalgae-bacterial symbionts on growth and lipid production by Chlorella vulgaris (C. vulgaris), as well as the inter-relationship between microalgae and bacterial in a photoautotrophic system. The results showed that compared to an axenic culture of C. vulgaris, H1 co-culture system (axenic C. vulgaris-Stenotrophomona smaltophilia) had the strongest effect on the C. vulgaris growth. The biomass, specific growth rate and maximum productivity of C. vulgaris were increased by 21.9, 20.4, and 18%, respectively. The bacteria in co-culture system had a significant effect on the accumulation of lipid and fatty acid components of C. vulgaris: the content of lipid was increased by 8.2-33.83%, and the components of the saturated fatty acids and oleic acids also had an obvious improvement. The results indicate that the microalgae-bacterial co-culture system can improve microalgal biomass and the quality of biodiesel.

“…4 When it is used as biomass raw for biofuel production it is often considered as microalgae. [4][5][6][7] Advantages of A. platensis are relatively simple and cheap technologies for its cultivation and harvesting and lability of biochemical composition, i.e. predictable response to changes in the external environment (illumination, temperature, limitation, and starvation of the main biogenic elements).…”

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.
