Affine magnetic sorbents supported on coal ash microspheres for recombinant protein isolation / L. A. Frank [et al.] // Applied Biochemistry and Microbiology. - 2009. - Vol. 45, Is. 2. - P215-220, DOI 10.1134/S0003683809020173 . - ISSN 0003-6838

Clytia gregaria -- Obelia longissima
Аннотация: The results of the development and utilization of an affine magnetic sorbent with Ni2+ ions immobilized on coal ash microspheres are reported. The applicability of the material in the isolation of Histag proteins is demonstrated by examples of the recombinant green fluorescent protein from Clytia gregaria and the Ca2+ regulated photoprotein obelin from Obelia longissima. The specific sorption capacity of the sorbent was 2-7 mg/cm3 for medium-size proteins (20-30 kDa). The particles are suitable for chromatography with the presence of chaotropic agents and EDTA. They are easy to manipulate as isolation of a target protein takes 30-35 min. On the one hand, the elevated affinity of the sorbent to proteins rich in native histidines may result in a high degree of irreversible sorption; on the other hand, it allows isolation of such proteins without the introduction of artificial polyhistidine fragments.

Аннотация: Two-section enclosures were designed for the investigation of the effect of various physicochemical and biological factors on vertical distribution of zooplankton in situ. The framework of the enclosure was a cylindrical polyethylene column without any partitions inside, in which the isolation of animals in different sections after in situ exposure was achieved by pinching the flexible central part of the column. Enclosures were tested at the brackish stratified meromictic Lake Shira (Russia, Khakasia). The absence of fish and carnivorous zooplankton in the lake suggests that the vertical distribution of zooplankton is mainly determined by physicochemical gradients in the water column. Experiments and field observations demonstrated that all age and size groups of Arctodiaptomus salinus and Brachionus plicatilis strongly avoided surface layers during the daylight. The escape of zooplankton from the anoxic hypolimnion was less active. Statistically significant avoidance was observed only for copepodites C4-C5 and females of A. salinus. The relatively simple construction of the columns and easy handling during the experiment were the factors that favoured the use of this device to perform in situ basic tests of the effect of different factors on the vertical distribution of zooplankton.

Аннотация: By the method of exhaustive hydroponically obtained essential oil from beans of Heracleum dissectum Ledeb., growing in the Krasnoyarsk region. Separate fractions of oil were obtained: the first after 45 minutes from the beginning of distillation, the second – after 2 hours, the third-after 5 hours, the fourth fraction was collected after the end of hydro-distillation. The component composition of both whole essential oil and its separate fractions was studied. The main components are octyl acetate (60.0%), octyl-2-methylpropanoate (10.2%), n-hexyl-2-methylbutanoate (9.0%). The main amount of octyl acetate (64.7%) is concentrated in the first fraction of the oil. The antimicrobial activity of various fractions of essential oil of borscht dissected against strains of opportunistic microorganisms: Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus 209p, MRSA, Proteus vulgaris. It was found that, depending on the duration of isolation, the antimicrobial activity of essential oil fractions in relation to Staphylococcus aureus 209p, MRSA and Pseudomonas aeruginosa decreases, and in relation to Escherichia coli, Klebsiella pneumoniae and Proteus vulgaris increases. The most pronounced inhibitory effect of the third and fourth fractions of essential oil against Klebsiella pneumonia. The antiradical activity of all studied samples of borscht essential oil dissected in reaction with stable free 2,2-diphenyl-1-picrylhydrazyl radical was established. The first fraction showed minimal antiradical activity (15.1%), the fourth – maximum (49.2%). © 2020 Altai State University. All rights reserved.

Аннотация: The Institute of Biophysics SB RAS hosts and maintains a specialized collection of luminous bacteria (CCIBSO 836) containing over 700 strains isolated in various regions of the world's oceans. The culture collection is a source of lux genes and biologically active substances. The wide application of bioluminescence in medicine and ecology has given importance to analys-ing information on the structure and functioning of bioluminescence systems in natural and transgenic microorganisms, as well as on their features that are closely interrelated with bioluminescence. The aims of our BIOLUMBASE database are: gathering information on microorganisms with lux genes, their analysis and free access, and distribution of this data throughout the global network. The database includes two sections, natural and transgenic luminous microorganisms, and is updated by our own experimental results, the published literature and internet resources. For the future, a publicly available internet site for BIOLUMBASE is planned. This will list the strains and provide comprehensive information on the properties and functions of luminous bacteria, the mechanisms of regulation of bioluminescence systems, constructs with lux genes, and applications of bioluminescence in microbiology, ecology, medicine and biotechnology. It is noteworthy that this database will also be useful for evaluation of biological hazards of transgenic strains. Users will be able to carry out bibliographic and strain searches starting from any feature of interest. Copyright В© 2005 John Wiley & Sons, Ltd.

Effect of bacterial population density on germination wheat seeds and dynamics of simple artificial ecosystems / L.A Somova [et al.] // Advances in Space Research. - 2001. - Vol. 27, Is. 9. - P1611-1615, DOI 10.1016/S0273-1177(01)00257-5 . - ISSN 0273-1177

Аннотация: Effect of the size of rhizospheric bacterial populations on germination of seeds and development of simple terrestrial "wheat plants - rhizospheric microorganisms - artificial soil" and "wheat plants - artificial soil" systems has been studied. Experiments demonstrated that within specify ranges in the inoculate, the rhizospheric bacteria are capable of increasing the yield of germinated seeds and stimulate the growth of plantlets. Germination of seeds inoculated with bacteria was either stimulated, or inhibited or remained at control levels depending on the amount of bacteria. Plant biomass growth and total photoassimilation has been found to depend on the amount of bacteria on the plant roots: the higher the amount of bacteria on plant roots, the smaller is the biomass of plants but the total photoassimilation is, higher. Thus, depending on the amount of bacteria on the roots of plants the system either increases the biomass of plants or increases the total photoassimilation, i.e. "pumps" carbon through itself involving bacteria.

Аннотация: Using the original technique of treating biomass with beta-glucosidase, a pool of extracellular fungal enzymes was obtained for the first time from the mycelium of basidiomycete Neonothopanus nambi. Two protein fractions containing enzymes with oxidase activity were isolated from the extract by gel-filtration chromatography and conventionally called F1 and F2. Enzyme F1 has a native molecular weight of 80-85 kDa and does not contain chromophore components; however, it catalyzes the oxidation of veratryl alcohol with K-m = 0.52 mM. Probably, this enzyme is an alcohol oxidase. Enzyme F2 with a native molecular weight of approximately 60 kDa is a FAD-containing protein. It catalyzes the cooxidation of phenol with 4-aminoantipyrine without the addition of exogenous hydrogen peroxide, which distinguishes it from the known peroxidases. It was assumed that this enzyme may be a mixed-function oxidase. F2 oxidase has K-m value 0.27 mM for phenol. The temperature optimums for oxidases F1 and F2 are 22-35 and 55-70 degrees C, and pH optimums are 6 and 5, respectively.

Аннотация: Industrial sea food residues, mainly crab and shrimp shells, are considered to be the most promising and abundant source of chitin. In-depth understanding of the biological properties of chitin and scientific advancements in the field of nanotechnology have enabled the development of high-performance chitin nanomaterials. Nanoscale chitin is of great economic value as an efficient functional and reinforcement material for a wide range of applications ranging from water purification to tissue engineering. The use of polymers and nanochitin to produce (bio) nanocomposites offers a good opportunity to prepare bioplastic materials with enhanced functional and structural properties. Most processes for nanochitin isolation rely on the use of chemical, physical or mechanical methods. Chitin-based nanocomposites are fabricated by various methods, involving electrospinning, freeze drying, etc. This review discusses the progress and new developments in the isolation and physico-chemical characterization of chitin; it also highlights the processing of nanochitin in various composite and functional materials.

Аннотация: A green flavoprotein (GFP) was isolated and purified to homogeneity from Photobacterium leiognathi, strain 208. GFP is a homodimer of molecular weight 54,000 and contains two molecules of an unusual flavin per molecule of protein. Various biochemical characteristics including isoelectric point, trypsin and chymotrypsin degradation, SDS and temperature influence on subunit dissociation and the dissociation of the flavin chromophore, were investigated. The sequence of 23 N-terminal amino acids was determined and found to be concurrent with the N-terminal amino acid sequence encoded by the lux G(N) gene of P. leiognathi. This fact suggests that GFP is a structural component of the Photobacterium luminescence system.

Аннотация: Previous studies have stated that aequorin loses most of its bioluminescence activity upon modification of the C-terminus, thus limiting the production of photoprotein fusion proteins at its N-terminus. In the present work, we investigate the importance of the C-terminal proline and the hydrogen bonds it forms for photoprotein active complex formation, stability and functional activity. According to the crystal structures of obelin and aequorin, two Ca2+-regulated photoproteins, the carboxyl group of the C-terminal Pro forms two hydrogen bonds with the side chain of Arg21 (Arg15 in aequorin case) situated in the first a-helix. Whereas, deletion or substitution of the C-terminal proline could noticeably change the bioluminescence activity, stability or the yield of an active photoprotein complex. Therefore, modifications of the first alpha-helix Arg has a clear destructive effect on the main photoprotein properties. A C-terminal hydrogen-bond network is proposed to be important for the stability of photoprotein molecules towards external disturbances, when taking part in the formation of locked protein conformations and isolation of coelenterazine-binding cavities.

Аннотация: Genes encoding luminescence of Photobacterium leiognathi have been cloned in Escherichia coli. The luminescent clones were readily apparent. Among them, a clone containing a recombinant plasmid with a 13.5-kb insertion was identified. This DNA fragment contained all of the luminescence-encoding genes. The luciferase-encoding genes (lux) in this DNA fragment were localized. We have sequenced a part of the cloned lux region and identified the luxA, luxB and luxG genes encoding the ? and ? subunits of luciferase and a ? protein with an Mr of 26 180, respectively. The analysis of deduced amino acid sequences and comparison with known luciferase sequences from Vibrio harveyi, indicate the common origin of these proteins. В© 1990.

Аннотация: The analysis of the literature on the methods of soluble organosolv lignins isolation, their physical-chemical study and on the method of their processing to porous aerogels and liquid hydrocarbons was carried out. A review of the literature allowed us to choice of the most important areas of research. For isolation from wood the soluble lignins free from sulfur the methods of catalytic peroxide delignification at mild conditions (temperature <= 100 degrees C, atmospheric pressure) and methods of lignin extraction by supercritical organic solvents were used. Molecular mass and molecular-mass distribution of ethanol-lignin samples isolated from aspenwood and abies-wood were studied by gel-permeation chromatography. Weighted molecular mass of ethanol-lignin from abies wood is 478 Da and that from aspen wood ethanol-lignin - 750 Da. Thus, the studied samples of ethanol-lignin have rather low molecular mass, what should facilitate their further processing to liquid hydrocarbons and aerogels. For the depolymerization of organosolv lignins to liquid hydrocarbons the processes of their catalytic conversion in supercritical alcohols have good prospects for the use. In the processes of lignin thermal conversion alcohols can to extract the products of lignin depolymerization and to alkylate these products, preventing their repolymerization to high molecular mass substances. To obtain a new class of nanoporous materials based on lignin the methods of organic aerogels synthesis from mixtures of lignin with other natural polymers and crosslinking agents were applied. It was found that the structure and properties of porous materials of aerogel type depend not only from the reaction mixture composition but from the method of drying. Drying in subcritical conditions leads to the formation of xerogels, in supercritical conditions - to the formation aerogels and the freezdrying - of cryogels. Obtained porous materials can have very low density (around 0.2 g/cm(3)), high specific surface area (to 500 m(2)/g) and the pore volume near 5 cm(3)/g.
