Biosynthesis of Multi-component Polyhydroxyalkanoates by the Bacterium Wautersia Eutropha
The study addresses the effect of different conditions of carbon nutrition on synthesis of polyhydroxyalkanoates by the bacterium Wautersia eutropha. In experiments with two wild-type strains (H16 and B5786) it has been first found that under mixotrophic growth conditions β CO2 + co-substrate (alkanoic acids) β bacteria can synthesize multi-component PHAs, consisting of short- and medium-chain-length monomers with carbon chains containing 4 to 8 atoms. It has been shown that PHA composition is determined by the type of the co-substrate. Fatty acids with odd number of carbons induce bacteria to synthesize four- and five-component PHAs with hydroxybutyrate, hydroxyvalerate, and hydroxyhexanoate as major monomers and hydroxyhexanoate and hydroxyoctanoate as minor, occasionally occurring, ones. Fatty acids with even number of carbons induce synthesis of not only their respective monomers (hydroxyhexanoate and hydroxyoctanoate) but also hydroxyvalerate, making possible synthesis of four-component PHAs, containing hydroxybutyrate and hydroxyhexanoate as major components (up to 18 mol%). A family of short- and medium-chain-length four- and five-component PHAs has been synthesized and their physicochemical properties examined

of Cupriavidus eutrophus B-10646 were studied, using various carbon sources (fructose, glucose,
oleic acid, sunflower seed oil). The best substrates for biomass production (7.8-8.6 g/l) and polymer
synthesis (7.3-7.9 g/l) were sugars and oleic acid. Bacterial cells grown on sugars and sunflower seed
oil synthesized only homopolymer poly(3-hydroxybutyrate). 3-hydroxyvalerate (2.0-4.2 mol. %) was
identified in polymer when Cupriavidus eutrophus used oleic acid as sole carbon source. Study of
total fatty acid composition of lipids showed that major fatty acids were palmitic (16:0), palmitoleic
(16:1Ο7), and cis-vaccenic (18:1Ο7) acids. When carbohydrate substrate was replaced by oleic acid
or sunflower seed oil, the proportion of oleic acid in the total fatty acids increased considerably. In
addition to that, the lipid fatty acids of bacterial cells grown on sunflower seed oil also contained
linoleic acid, which is the major acid of sunflower seed oi
Salicornia europaea L. (fam. Chenopodiaceae) Plants as Possible Constituent of Bioregenerative Life Support Systemsβ Phototrophic Link
The work is devoted to investigation of productivity, biochemical and mineral composition of Salicornia europaea grown under intensive light culture conditions as applied to bioregenerative life support systems (BLSS). Furthermore influence of amide form of nitrogen on plants growth is investigated in the work. Biochemical composition of the Salicornia europaea edible part showed that raw protein was contained in the highest degree. The water-soluble sugars content and the polysaccharides number (except cellulose) were not high in the Salicornia europaea edible part. It was shown that the plants lipids are characterized by a high unsaturation degree mainly due to alpha linolenic and linoleic acids. Nitrogen nutrition form did not significantly affect the Salicornia europaea productivity. Sodium and its concentrations predominated in the plants mineral composition. Hence Salicornia europaea vegetable plants not only contribute to involvement of sodium chloride in BLSS matter turnover, but also can be the source of several biochemical substances and essential fatty acids for a human

Π±Π°ΠΊΡΠ΅ΡΠΈΠΉThe investigation of dynamics of 1,214Π‘-acetate flows was carried out in three different regimes
of bacteria Cupriavidus eutrophus B-10646 biosynthesis on fructose and acetate: a) in the phase
of accumulation of polyhydroxybutyrate; b) in the phase of intracellular PHB degradation and
the synthesis of nitrogen compounds; c) in the phase of resynthesis of PHB. It has been shown
that in regime of PHB accumulation 80 % of labeled carbon was used for synthesis of PHB. At
the condition of PHB degradation both synthesis and degradation take place simultaneously. This
confirms the cyclic nature of PHB methabolis
Distribution and Resorption of Intravenously Administrated Polymer Microparticles in Tissues of Internal Organs of Laboratory Animals
Resorbable polymer of hydroxybutyric acid labeled with 14C was used to prepare microparticles
(diameter smaller than 3.8 ΞΌm ) that were then injected to laboratory animals (Wistar rats) via the tail
vein, without causing any adverse effects on growth and development of the animals or altering the
macroscopic and microscopic structure of the tissues of internal organs. Examination of the distribution
of microparticles among the internal organs and the dynamics of accumulation of carbon-containing
polymer degradation products in internal organs showed that the main targets for microparticles were
tissues of the liver, kidneys, and spleen. The most rapid degradation of the polymer of microparticles
occurred in the spleen and liver. The presence of high molecular weight polymer registered in internal
organs suggested that the microparticles remained undecomposed and that the PHB microparticles
could function in vivo for extended periods of time (up to 12 weeks).Π‘ ΠΏΡΠΈΠΌΠ΅Π½Π΅Π½ΠΈΠ΅ΠΌ ΡΠ΅Π·ΠΎΡΠ±ΠΈΡΡΠ΅ΠΌΠΎΠ³ΠΎ ΠΏΠΎΠ»ΠΈΠΌΠ΅ΡΠ° Π³ΠΈΠ΄ΡΠΎΠΊΡΠΈΠΌΠ°ΡΠ»ΡΠ½ΠΎΠΉ ΠΊΠΈΡΠ»ΠΎΡΡ, ΠΌΠ΅ΡΠ΅Π½ΠΎΠ³ΠΎ ΠΏΠΎ 14C,

The capability of snails to consume and convert inedible plant biomass and kitchen waste was tested.
Inedible biomass of wheat and cabbage and also potato peels as a food were worse than lettuce, which
is an ordinary feed for snails. In order to describe the growth of Achatina fulica its logistic function was
fitted to the experimental data. It was found that calculated specific growth rate and carrying capacity,
as constants of the logistic function, are 1.06 month-1 and 250 g of wet weight correspondingly. Mass
ratio shell/whole body in terms of wet weight was 18-21 % irrespective of snail age. Snail meat was
characterized by the low content of fat β 6.0 % DM. Essential fatty acids constituted 16.6 % of the
total sum. Linolenic and linoleic acids dominated in a pool of essential fatty acids. The scores of
essential amino acids, except sulfuric amino acids, exceeded 100 %. To estimate nutritious properties
of snail meat, a computer program was developed. It was observed that the maximum intake of snail
meat can reach 497 g/crewmember day. Addition of snail meat to a basic diet enabled increasing food

of Cupriavidus eutrophus B-10646 were studied, using various carbon sources (fructose, glucose,
oleic acid, sunflower seed oil). The best substrates for biomass production (7.8-8.6 g/l) and polymer
synthesis (7.3-7.9 g/l) were sugars and oleic acid. Bacterial cells grown on sugars and sunflower seed
oil synthesized only homopolymer poly(3-hydroxybutyrate). 3-hydroxyvalerate (2.0-4.2 mol. %) was
identified in polymer when Cupriavidus eutrophus used oleic acid as sole carbon source. Study of
total fatty acid composition of lipids showed that major fatty acids were palmitic (16:0), palmitoleic
(16:1Ο7), and cis-vaccenic (18:1Ο7) acids. When carbohydrate substrate was replaced by oleic acid
or sunflower seed oil, the proportion of oleic acid in the total fatty acids increased considerably. In
addition to that, the lipid fatty acids of bacterial cells grown on sunflower seed oil also contained
linoleic acid, which is the major acid of sunflower seed oi
Salicornia europaea L. (fam. Chenopodiaceae) Plants as Possible Constituent of Bioregenerative Life Support Systemsβ Phototrophic Link
The work is devoted to investigation of productivity, biochemical and mineral composition of Salicornia europaea grown under intensive light culture conditions as applied to bioregenerative life support systems (BLSS). Furthermore influence of amide form of nitrogen on plants growth is investigated in the work. Biochemical composition of the Salicornia europaea edible part showed that raw protein was contained in the highest degree. The water-soluble sugars content and the polysaccharides number (except cellulose) were not high in the Salicornia europaea edible part. It was shown that the plants lipids are characterized by a high unsaturation degree mainly due to alpha linolenic and linoleic acids. Nitrogen nutrition form did not significantly affect the Salicornia europaea productivity. Sodium and its concentrations predominated in the plants mineral composition. Hence Salicornia europaea vegetable plants not only contribute to involvement of sodium chloride in BLSS matter turnover, but also can be the source of several biochemical substances and essential fatty acids for a human

of bacteria Cupriavidus eutrophus B-10646 biosynthesis on fructose and acetate: a) in the phase
of accumulation of polyhydroxybutyrate; b) in the phase of intracellular PHB degradation and
the synthesis of nitrogen compounds; c) in the phase of resynthesis of PHB. It has been shown
that in regime of PHB accumulation 80 % of labeled carbon was used for synthesis of PHB. At
the condition of PHB degradation both synthesis and degradation take place simultaneously. This
confirms the cyclic nature of PHB methabolis
