Аннотация: Biodegradation of microbial linear polymers of hydroxyalkanoic acids (polyhydroxyalkanoates, PHAs) by soil microbial communities of different structures has been studied during two field seasons in different weather conditions. This process was shown to be influenced by the polymer chemical composition, temperature, humidity, and the microbial soil component. The PHA degradation was accompanied by a decrease in the polymer molecular weight and an increase in the degree of crystallinity, indicating the preferential destruction of the amorphous phase compared to the crystalline one. The quantity of the true PHA destructors developing at the surface of the polymer samples was lower than the quantity of accompanying bacteria. The dominant PHA degrading microorganisms under the test conditions were identified as bacteria of the genera Variovorax, Stenotrophomonas, Acinetobacter, Pseudomonas, Bacillus, and Xanthomonas and as micromycetes from Penicillium, Paecilomyces, Acremonium, Verticillium, and Zygosporium.

Biogenic nanoparticles produced by bacteria Klebsiella Oxytoca: structure investigations : Chapter / M. Balasoiu [и др.] // Modern trends of nanoscience / ed.: M. Balasoiu, G. M. Arzumanian. - Bucharest : Publishing House of Romanian Academy, 2012. - Chapter. - P. 179-186 . - ISBN 978-973-27-2230-5
Аннотация: A promising new dimension in this field is the use of microorganisms for the production of inorganic nanoscale particles. The clean, nontoxic and environmentally friendly ability of eukaryotic and prokaryotic microorganisms to form nanoparticles either intra- or extra-cellularly is particularly important in the development of nanobiotechnology. The development of techniques for the synthesis of nanoparticles of well-defined size, shape and composition is a challenge and an important area of research. Steps in the methodological work for structural properties determination of biogenic ferrihydrite nanoparticles by means of small angle techniques are reviewed.

Аннотация: Ferrihydrite nanoparticles (2-5 nm in size) produced by bacteria Klebsiella oxytoca in the course of biomineralization of iron salt solutions from a natural medium exhibit unique magnetic properties: they are characterized by both the antiferromagnetic order inherent in a bulk ferrihydrite and the spontaneous magnetic moment due to the decompensation of spins in sublattices of a nanoparticle. The magnetic susceptibility enhanced by the superantiferromagnetism effect and the magnetic moment independent of the magnetic field provide the possibility of magnetically controlling these natural objects. This has opened up the possibilities for their use in nanomedicine and bioengineering. The results obtained from measurements of the magnetic properties of the ferrihydrite produced by Klebsiella oxytoca in its two main crystalline modifications are reported, and the data obtained are analyzed theoretically. This has made it possible to determine numerical values of the magnetic parameters of real biomineral nanoparticles.

Аннотация: Three results are presented. First, we prove the existence of a universal 7-cluster structure in all 143 completely sequenced bacterial genomes available in Genbank in August 2004, and explained its properties. The 7-cluster structure is responsible for the main part of sequence heterogeneity in bacterial genomes. In this sense, our 7 clusters is the basic model of bacterial genome sequence. We demonstrated that there are four basic "pure" types of this model, observed in nature: "parallel triangles", "perpendicular triangles", degenerated case and the flower-like type. Second, we answered the question: how big are the position-specific information and the contribution connected with correlations between nucleotide. The accuracy of the mean-field (context-free) approximation is estimated for bacterial genomes. We show that codon us-age of bacterial genomes is a multi-linear function of their genomic G+C-content with high accuracy (more precisely, by two similar functions, one for eubacterial genomes and the other one for archaea). Description of these two codon-usage trajectories is the third result. All 143 cluster animated 3D-scatters are collected in a database and is made available on our web-site: http://www.ihes.fr/similar to zinovyev/7clusters. (c) 2005 Elsevier B.V. All rights reserved.

Аннотация: The precipitation of iron and associated heavy metals in industrial waste water and in model solution using ferritization and aerobic bacterial culture was investigated. Magnetic sediments extractable by magnetic separation (specific saturation magnetization of 16–36.8 G cm3/g) were produced by precipitation of iron by ferritization method at рН (8–10) and 60–80°С for 15–30 min. Nanoparticles of ferrihydrite or ferric hydroxide doped with associated metals (Co, Ni) were produced under precipitation of ferric iron in model solution with bacteria at the temperature 26–34°С. The radii of synthesized particles are 1–5 nm and nanoparticles of ferrihydrite are superparamagnetic in both un-doped and doped (Co, Ni, Zn) sets. Dispersed structure of biogenic nanoparticle sols, their magnetic and other properties were studied by atomic force microscopy, X-ray small-angle scattering, X-ray diffraction, electron magnetic resonance, Mössbauer and X-ray photoelectron spectroscopy.

Antioxidant activity -- Bacterial enzymes -- Fullerenol -- Hormesis -- Luminous marine bacteria -- Ultralow concentrations
Аннотация: Fullerenols are nanosized water-soluble polyhydroxylated derivatives of fullerenes, specific allotropic form of carbon, bioactive compounds and perspective pharmaceutical agents. Antioxidant activity of fullerenols was studied in model solutions of organic and inorganic toxicants of oxidative type – 1,4-benzoquinone and potassium ferricyanide. Two fullerenol preparations were tested: С60О2–4(ОН)20–24 and mixture of two types of fullerenols С60О2–4(ОН)20–24+С70О2–4(ОН)20–24. Bacteria-based and enzyme-based bioluminescent assays were used to evaluate a decrease in cellular and biochemical toxicities, respectively. Additionally, the enzyme-based assay was used for the direct monitoring of efficiency of the oxidative enzymatic processes. The bacteria-based and enzyme-based assays showed similar peculiarities of the detoxification processes: (1) ultralow concentrations of fullerenols were active (ca 10–17–10−4 and 10–17–10−5 g/L, respectively), (2) no monotonic dependence of detoxification efficiency on fullerenol concentrations was observed, and (3) detoxification of organic oxidizer solutions was more effective than that of the inorganic oxidizer. The antioxidant effect of highly diluted fullerenol solutions on bacterial cells was attributed to hormesis phenomenon; the detoxification was concerned with stimulation of adaptive cellular response under low-dose exposures. Sequence analysis of 16S ribosomal RNA was carried out; it did not reveal mutations in bacterial DNA. The suggestion was made that hydrophobic membrane-dependent processes are involved to the detoxifying mechanism. Catalytic activity of fullerenol (10−8 g/L) in NADH-dependent enzymatic reactions was demonstrated and supposed to contribute to adaptive bacterial response.

Аннотация: A bioluminescent assay based on a system of coupled enzymatic reactions catalyzed by bacterial luciferase and NADH:FMN-oxidoreductase was developed to monitor toxicity and antioxidant activity of bioactive compounds. The assay enables studying toxic effects at the level of biomolecules and physicochemical processes, as well as determining the toxicity of general and oxidative types. Toxic and detoxifying effects of bioactive compounds were studied. Fullerenols, perspective pharmaceutical agents, nanosized particles, water-soluble polyhydroxylated fullerene-60 derivatives were chosen as bioactive compounds. Two homologous fullerenols with different number and type of substituents, C60O2–4(OH)20–24 and Fe0.5C60(OH) xOy (x + y = 40–42), were used. They suppressed bioluminescent intensity at concentrations 0.01 g L−1 and 0.001 g L−1 for C60O2–4(OH)20-24 and Fe0.5C60(OH)xOy, respectively; hence, a lower toxicity of C60O2–4(OH)20–24 was demonstrated. Antioxidant activity of fullerenols was studied in model solutions of organic and inorganic oxidizers; changes in toxicities of general and oxidative type were determined; detoxification coefficients were calculated. Fullerenol C60O2–4(OH)20–24 revealed higher antioxidant ability at concentrations 10−17−10−5 g L−1. The difference in the toxicity and antioxidant activity of fullerenols was explained through their electron donor/acceptor properties and different catalytic activity. Principles of bioluminescent enzyme assay application for evaluating the toxic effect and antioxidant activity of bioactive compounds were summarized and the procedure steps were described.

Аннотация: Confident effect of five magnetic composite nanoparticles (FeP@Ag, FeP@Pd, CoP, NiP, Fe2O3@AГ) on growth of test bacteria colonies (Acinetobacter baumannii, Еscherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus) in five replicates each is considered. Reliable inhibitors of colonies of all five test bacteria were nanoparticles FeP@Ag. CoP nanoparticles are reliable inhibitors of growth of 4 test bacteria (except for test bacteria Escherichia сoli). NiP nanoparticles are reliable inhibitors of growth of 2 test bacteria: Escherichia сoli and Klebsiella pneumoniae. Bacteria Escherichia сoli were most sensitive to the effect of magnetic nanoparticles; and bacteria Pseudomonas aeruginosa and Staphylococcus aureus were most resistant to the effect of magnetic nanoparticles. The prospects of the method are in the possibility of multiple reuse of the magnetic particles with antimicrobial properties for bacterial decontamination of the studied sources of water and removal of magnetic nanoparticles from the treated liquids by electromagnet. The method can find use in water treatment facilities for household, Industrial and medical wastes.
