The influence of the production conditions for rapeseed and soybean oils obtained by extraction in the system “solid – liquid” on the qualitative composition of the obtained vegetable oils has been studied.
Three ferrocenylmethylnucleobases (FcMeNb) were synthesized and characterized by cyclic voltammetry, electronic absorption, FT-IR and NMR spectroscopy. The energy of frontier molecular orbitals was determined using DFT/B3LYP method combined with 6-311++G(d,p) basis set in acetonitrile. The lower standard rate constant values of the FcMeNb compounds as compared to ferrocene indicated slower electron transfer kinetics.
Biogenic surfactants (rhamnolipid biocomplex, dirhamnolipid and exopolysaccharide) and polyhydroxyalkanoate biopolymer which are the new biosynthesis products of Pseudomonas sp. PS-17 strain have been obtained. The thermal transformation of these products has been studied in the air in the temperature range of 293–1273 K. Thermolysis and IR spectroscopy revealed a formation of rhamnolipid biocomplex between rhamnolipids and exopolysaccharide upon acidification of the culture fluid supernatant to pH = 3. Cellular polymer – polyhydroxyalkanoate – was identified by UV-Vis spectroscopy.
