We analyze the conditions (temperature, рН, physical and chemical features of substrates structure, a liquid growth medium, a cell surface, mass-transfer processes) which influence the optimal development of a biofilm, including an anode biofilm formed directly on the anode of a microbial fuel cell (МFC). We define that the quality and properties of the biofilm influence an extracellular polymeric matrix and the presence of quorum-sensing between members of microbial community.

Self-Organization of Magnetic Nanoparticles When Giving Magnetic Properties to Yeast Saccharomyces Cerevisiae
P. 27–33.
Fig. 4. Tabl. 1. Refs.: 10 titles.
We develop and conduct the compararative analysis of four evaluation methods of clusters parameters of magnetic nanoparticles. The magnetically-controllable biosorbent based on the S. cerevisiae culture is used as a model object for analyzing the adequacy of these models. Finally, we obtain the evaluation data on the depth of clusters penetration inside the biomembrane, typical sizes of clusters and dispersion of magnetic cluster sizes. Our analysis shows that all four methods can be used for single magnetic clusters. However, for clusters laying in chains with small distances between their centers, the model that takes into account the table meaning of magnetite magnetization can’t be used, because this model doesn’t take into account the nearest neighbors contribution of interaction of magnetic fields dipole with magnetic probe.

Stimulation of Accumulation of Biomass and Fermenting Activity of Saccharomyces cerevisiae Yeast Culture by Extra High Frequency Electromagnetic Irradiation
P. 68–73.
Fig. 1. Tabl. 4. Refs.: 24 titles.
The optimum irradiation parameters of EHF EMR for Saccharomyces cerevisiae M-09 yeast culture are experimentally determined. In the alcoholic brew, fermented with the irradiated yeast, the accumulation of biomass, alcohol and the amount of carbon dioxide emissions increased compared to control. Simultaneously the amount of nonfermented sugars decreased. The yeast vigor for the filtered brew yeast, their a-glucosidase and zymase activity enhanced. The effect of the EHF EMR action on the yeast culture remained for three generations and gradually weakened, which can be connected with Saccharomyces cerevisiae adaptation to the influence of external factors.

The present paper describes biohydrogen production methods according to the classification of energy sources used by microorganisms. We also conduct the comparative analysis of these processes. We describe the microorganism-producers, hydrogen formation reaction and optimal environmental parameters for every method of biohydrogen production. All these methods have their advantages and disadvantages. Crucially, we define the most optimal biohydrogen production way. Photobiological hydrogen production and biomass production should take place on the first stage. The formed biomass should be fermented on the second dark stage and its products will be used to produce biohydrogen by the bioelectrochemical method.

P. 123–128.
Fig. 2. Tabl. 1. Refs.: 24 titles.

The experimental data shows that the 5,9 V electrochemical window of pure and filled ionic liquid PYR14TFSI with the increased (to 30 %) electrical conductivity is stable. Such windows allow PYR14TFSI filled by nano-sized TiO2 to be used with very strong reducing and oxidizing electrode agents, yielding high cell voltage. Additionally, we consider various models for the disperse filling effect and discuss this effect on supercooling and glass transition.

The Effect of Temperature Change of the Solvent Properties on the Termodynamic Characteristics of Chemical Equilibrium in Solutions
P. 135–140.
Tabl. 6. Refs.: 12 titles.
This paper proposes a novel approach to dividing thermodynamic characteristics of the chemical equilibrium in solutions, calculated from the polytherm of equilibrium constants. The first component of the equilibrium constant characterizes the process; the second one is caused by the temperature change of the solvent properties. This approach suggests that the extreme on polytherm equilibrium constants appear not because of the change in the nature of the process in the solution, but because of the temperature variation of the solvent permittivity.

Quantum-Chemical Modelling of Functionalized Silica Surface
P. 141–145.
Fig. 4. Tabl. 1. Refs.: 13 titles.
Based on the quantum chemical modeling of silica surface (DFT (B3LYP/6-31G (d, p))) functionalized with phosphorus- and thiourea-containing groups [≡Si(CH2)2P(O)(OC2H5)2, ≡Si(CH2)2P(O)OH2 and ≡Si(CH2)3NHC(S) NHC2H5], we show that hydrogen bonds can be formed between donor and silanol groups in the T2 structural unit both in the presence and absence of water molecule. The functionalized xerogel surface was modeled by (HO)2Si(OH)R′ fragments, where R′ = –(CH2)2P(O)(OC2H5)2, –(CH2)2P(O)(OH)2 or –(CH2)3NHC(S)NHC2H5. Specifically, geometry is optimized and spectra frequencies are calculated for these fragments. We also show that the absorption band of stretching vibrations ν (PO) in the calculated IR spectra for fragments with an intermolecular hydrogen bond is slightly shifted to lower frequencies, but it significantly increases with the appearance of a water molecule.
