Classification and Analysis of Fermenters with Pneumatic Mixing

The analysis of constructions of fermenters with energy supply by compressed gas in view of features of hydrodynamics and math transfering in them, also there was made an observing of evolutionary progress of modern constructions. Based on this information, there was made the classification of fermenters with pneumatic mixing with the main idea was to find possible ways of designing and building such kind of equipment.

Carbon Nanostructures for Biotechnology: Technologies of Carbon Nanotube Synthesis with Definite Space Properties

The study summarizes major achievements in the field of single- and multi-layer carbon nanotube synthesis. We discuss the factors that influence the properties of carbon nanotubes. The method of chemical vapour deposition enables to control geometrics of carbon nanostructures. It is crucial for the target use in medicine biotechnology as a media for neuronal and endothelial cells at production of new effective systems for transportation of drugs and therapeutics, as well as in biosensors miniaturization.

Conditions of Formation and Structure of Biofilms

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.

Features of Preparation and Fermentation of Soybean Milk by the Representatives

The first stages of development of new laboratory technology sanitary sour-milk products on the basis by an especial mode cultivated seeds of soy have shown. For preparation soybean milk the soybean flour made according to new national technology ЕСО (producer ООО “ЕСО”) has used. The optimum technology of pretreatment of a soybean flour has found with the purpose of subsequent usage as a base for nutrient fermentations mediums. Has established, that milk from soy ЕСО “The present of the sun – Super” as much as possible induce biosynthetic processes for the strains L. delbrueckii subsp.

Morphological and Cultural and Biosynthetic Properties of Eremothecium Ashbyi Guill.

This paper considers the morphological and cultural properties of ascomycetes Eremothecium ashbyi F-340, a producer of riboflavin in various nutrient mediums. We also demonstrate the accretion of fungal biomass, the level of its riboflavin accumulation and the consumption of carbohydrates of nutrient mediums. Through experiments conducted, we determine that using the medium which contains wort in its composition is the most reasonable. Moreover, the riboflavin level in this medium is 2,8 times higher than in other mediums.

Investigation of Mediatorless Bioelectrogenes Process by Association of Anaerobic Microorganisms. Biotechnological Indices

We develop the approaches to classification of technological parameters of effectiveness evaluation of the mediatorless exoelectrogenesis process based on the system features. Moreover, we propose the ways of calculating the efficiency of biotechnological process parameters, namely the biomass growth (total and specific), the rate of substrate consumption (efficiency of wastewater purification), Coulomb efficiency and COD balance.

Boundary Temperatures for Cultivation of Basidiomycetes Mushrooms of Genus Coriolus Quel. in the Surface Culture

In this paper, we define the value of high and low boundary temperatures for 33 strains of basidiomycetes mushrooms of Coriolus. We prove the existence of strains variability for C. versicolor, C. zonatus, C. hirsutus depending on a high temperature. In addition, we obtain the research results on strains viability for C. zonatus, C. hirsutus and C. villosus at high temperatures for the first time ever.

The Influence of Temperature Incubation on Vitality of Vegetative Mycelia of Ganoderma applanatum (Pers.) Pat. and G. lucidum (Curtis) P. Karst. stains

The paper studies the influence of temperature incubation on vitality of vegetative mycelia of 40 mushroom stains of the Ganoderma genus. We determine that the species under study show strains specificity on vitality of vegetative mycelia at their incubation at 33–45 С. We also establish the critical growth temperature for vegetative mycelia of G. applanatum and G. lucidum stains.

Bioethics in Ukraine: from Theory to Practice. Legal, Scientific and Educational Aspects

We provide the insight into the background of bioethics and its differentiation at the present stage. Moreover, we consider the approaches to legal regulation in the field of bioethics at the international level and relevant domestic legislation. We also justify that bioethics should be introduced as an academic discipline for training specialists in biology, biotechnology and pharmacy.

Adaptation to cultivation conditions in vitro and increase of infectious titres of human rotaviruses, isolated on the territory of Ukraine

In this paper, we isolate and adapt five strains of rotaviruses for cultivation conditions from children with acute intestinal infections in HEP-2 human cell culture. We characterize the isolated strains ding to genotype and ability to increase the infectious titres during five consecutive passages. Crucially, we isolate the rotavirus strain, which has a special ability to adapt to cultivation conditions in human cell culture. This strain is promising for creating effective rotavirus vaccine for Ukrainians, as well as for developing diagnostic test-systems.
