Аннотация: The extent of inhibition of the bioluminescence reaction by wheat grain extracts was studied as a function of the scabby kernel content in wheat. The NADH : flavine mononucleotide oxidoreductase-luciferase bienzyme bioluminescence system was found to be the most sensitive to mycotoxins produced by fungi of the genus Fusarium. A biological luciferase test was developed for monitoring wheat grain infection with Fusarium.

A database on natural and transgenic luminous microorganisms: BiolumBase / S. E. Medvedeva [et al.] // Microbiology. - 2005. - Vol. 74, Is. 2. - P236-243, DOI 10.1007/s11021-005-0057-0 . - ISSN 0026-2617
Кл.слова (ненормированные):
Bioluminescence -- Database -- Natural and transgenic luminous microorganisms -- Bacteria (microorganisms)
Аннотация: The database BiolumBase was designed for the collection and systematization of available information on microorganisms containing bioluminescent systems; it includes two sections: natural and transgenic luminous microorganisms. By now, logic schemes of these sections have been developed, classification of the objects has been performed, ways of presentation of characteristics and structure of fields for input of information have been elaborated, and the necessary program modules have been developed. The database is filled on the basis of published data and our own experimental results; subsequent linkage of the database to the Internet is envisaged. Users will be able to obtain not only catalogues of strains but also information concerning the properties and functions of the known species of luminous bacteria, the structure, regulatory mechanisms, and application of bioluminescent systems and genetically engineered constructions with lux genes, as well as to find references and to search strains by using any set of attributes. The database will provide information that is of interest for the development of microbial ecology and biotechnology, in particular, for the prediction of biological hazard from the application of transgenic strains.

Аннотация: A mathematical model concerning the interaction of plants and rhizospheric microorganisms on complete mineral medium and under nitrogen limitation has been constructed. The model takes into account the closeness of plants and microorganisms in terms of the matter released by the plant and consumed by the microorganisms. The effect of rhizospheric microorganisms on plant growth with normal carbon dioxide and complete mineral medium has been demonstrated. Plants interacting with microorganisms have a greater biomass than plants growing without microorganisms. Wheat growth stimulation by metabolites of rhizospheric microorganisms under laboratory conditions on artificial soil has been experimentally demonstrated (Pechurkin, 1997). Under nitrogen limitation , the biomass of plants, with or without microorganisms, is identical, and is substantially reduced as compared with the medium with standard nitrogen. В© 1999 COSPAR.

A NEW EXPERIMENTAL APPROACH TO THE SEARCH FOR CHEMICAL DENSITY FACTORS IN THE REGULATION OF MONOCULTURE GROWTH [Text] / A. G. DEGERMENDZHY, V. V. ADAMOVICH, V. A. ADAMOVICH // J. Gen. Microbiol. - 1993. - Vol. 139. - P2027-2031. - Cited References: 7 . - 5. - ISSN 0022-1287

РУБ Microbiology

Аннотация: In monocultures of micro-organisms, growth is controlled by feedback mechanisms involving chemical factors such as limiting substrates and inhibitory metabolic products. The role of such feedback in the growth regulation of Escherichia coli O-124 was investigated by growing cells in batch culture using a medium containing glucose and mineral salts. In various phases of growth, portions of the native culture were diluted with culture filtrate, so that although cell density decreased, the chemical composition of the growth medium was unaltered. As the diluted cultures grew, variations in growth acceleration were calculated and compared with those of native (undiluted) cultures. Towards the end of the exponential phase and in the growth deceleration phase, the specific feedback level (FBL) was between -20 and -200 (h g l-1)-1. The feedback components resulting from changes in glucose concentration were calculated using experimentally determined values of mu(max) (0.55 +/- 0.05 h-1) and K(s) (2.5 +/- 0.7 mg l-1). Only 0.1-40% of FBL could be accounted for by changes in glucose concentration, indicating the presence of additional growth regulators. The method developed may become a new tool for determination of growth-regulating cell-density factors in microbial cultures.

A NEW EXPERIMENTAL-METHOD TO REVEAL DENSITY-DEPENDENT CHEMICAL FACTORS INVOLVED IN MICROBIAL-POPULATION GROWTH-CONTROL [Text] / A. G. DEGERMENDZHI, V. V. ADAMOVICH, V. A. ADAMOVICH // Microbiology. - 1993. - Vol. 62, Is. 3. - P308-313. - Cited References: 11 . - 6. - ISSN 0026-2617

РУБ Microbiology

Аннотация: Experiments based on an earlier developed theory with a culture of Escherichia coli 0-124 were undertaken to determine the feedback strength (FBS) in growth control. FBS is defined as the change in growth acceleration brought about by a discontinuous reduction in microbial concentration under conditions of constant chemical composition of the medium, and is an over-all measure of the regulatory influence of all chemical factors dependent on biomass concentration. FBS was determined for batch cultivation with glucose. In various growth phases the culture was diluted by its own filtrate and then the change in growth acceleration as compared to the control was measured. FBS was reliably different from zero at the end of the exponential phase and in the phase of decelerated growth and was of the order of -20 to -200 (h.g/liter)(-1). The feedback component due to glucose alone was estimated using the obtained relation between specific growth rate and glucose concentration (mu(max) = 0.55 +/- 0.05 h(-1), K-s = 2.5 +/- 0.7 mg/liter). The glucose-dependent regulatory contribution to FBS was found to be as low as 0.5 to 40%, which suggests the presence of other growth control factors. Upon accuracy improvements, this method may develop into an accepted microbiological tool for identifying major density-dependent factors involved in microbial growth control.

Аннотация: Adaptation of the Bacillus subtilis strain 2335/105 (Km(r)Inf(+)) containing a recombinant plasmid encoding the extracellular human interferon alpha 2 was studied under various conditions. Stability of the plasmid in the population of B. subtilis 2335/105 was estimated under nonselective conditions. The plasmid-free cells and cells with a low number of plasmid copies were found to accumulate progressively, constituting 80% of the population after 10 culture passages, indicating the poor competitiveness of cells carrying a high number of plasmid copies. The behavior of vegetative cells of the recombinant strain introduced into aquatic microcosms differing in trophic chain length was studied. Within the first 10 days, the lysis of vegetative cells of B. subtilis 2335/105 occurred; the number of viable spores was very low but remained constant for half a year.

Аннотация: The synthesis of polyhydroxybutyrate by the carboxydobacterium Seliberia carboxydohydrogena under various growth conditions was studied. The bacterium was able to accumulate poly-beta-hydroxybutyric acid and a heteropolymer that was a product of copolymerization of hydroxybutyric and hydroxyvaleric acids. Nitrogen and sulfur exerted the strongest effect on polymer accumulation in carboxydobacteria: The maximum polymer concentrations in cells reached 28%. Specimens of polyhydroxybutyrate films were obtained, and their degradability by soil microflora was shown.

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: Strain AIS(T), an aerobic halophilic, Gram-reaction-negative, heterotrophic bacterium isolated from the water of Shira Lake in Khakasia, southern Siberia, was characterized using a polyphasic approach. Our analysis of the 16S rRNA gene sequences showed that 'Aliidiomarina haloalkalitolerans', 'Allidiomarina sanyensis', Idiomarina maris and AIS(T) formed a distinct lineage. The sequence similarities between AIS(T) and the type strains of species of the genera Idiomarina and Aliidiomarina were 91.6-95.1 % and 94.0-96.9 %, respectively. The major isoprenoid quinone of AIS(T) was ubiquinone 8 (Q-8). Predominant cellular fatty acids were iso-C-17:0, iso-C-15:0 and summed feature 9. The genomic DNA G+C content was 45.8 mol%. It is concluded that AIS(T) represents a novel species of the genus Aliidiomarina, and the name Aliidiomarina shirensis sp. nov. is herein proposed for it. The type strain is AIST (=JCM 17761(T)=BCRC 80327(T)). Based on its fatty acid profile and our phylogenetic analysis, we propose that Idiomarina mans be transferred to the genus Aliidiomarina.

Аннотация: A number of approaches have been proposed and tested to transfer enzymatic reactions into the functional elements of microfluidic chips on the example of the bienzyme bioluminescent reaction involving NAD(P)H:FMN-oxidoreductase and luciferase. Measurement of the catalytic activity of these enzymes (under the influence of pollutants) is the basis of enzymatic bioassay of various liquids. It was found that all of the components of the reaction must be placed in the same cell of the chip to improve the reproducibility of the measurements. The use of starch gel as a carrier for immobilization and gelatin as a scaffold in the reactor of the chip enables the preservation of enzyme activity in the course of sealing the chip at room temperature. It is shown that the components of the reaction should be vigorously stirred in a microfluidic chip reactor to improve the efficiency of the analysis. As a result of the studies, a prototype of microfluidic chip based on the enzymatic bioluminescent reaction is proposed. It is characterized by a detection limit of copper sulfate of 3 mu M that corresponds to the sensitivity of traditional lux-biosensors based on living cells. The analysis time is reduced to 1 min, and the analysis can be performed by individuals without special laboratory skills.

Аннотация: The anoxygenic phototrophic bacterial community of the brackish meromictic Lake Shira (Khakassia) was investigated in August 2001, July 2002, and February-March 2003. In all the periods of investigation, the prevailing microorganisms were purple sulfur bacteria similar to Lamprocystis purpurea in morphology and pigment composition. Their highest number (3 ? 10 5 cells/ml) was recorded in July 2002 at the depth of 15 m. According to 16S rRNA gene analysis, the strain of purple sulfur bacteria isolated in 2001 and designated ShAm01 exhibited 98.6% similarity to the type strain of Thiocapsa roseopersicina and 97.1-94.4% similarity to the type strains of Tca. pendens, Tca. litoralis, and Tca. rosea. The minor microorganisms of the anoxygenic phototrophic bacterial community within the period of investigation were nonsulfur purple bacteria phylogenetically close to Rhodovulum strictum (98.3% similarity, strain ShRb01), Ahrensia kielensis (of 93.9% similarity, strain ShRb02), Rhodomicrobium vannieli (of 99.7% similarity, strain ShRmc01), and green sulfur bacteria, phylogenetically close to Chlorobium limicola (of 98.7% similarity, strain ShCl03).

Аннотация: Colonies of Flavobacterium sp. 56 and Flavobacterium sp. 22 were studied by electron microscopy without being washed off from solid nutrient medium and were shown to differ in the spatial arrangement and ultrastructure of their cells. Colonies of Flavobacterium sp. 56 contained a single type of cells, while those of Flavobacterium sp. 22 consisted of cells of two types differing in their ultrastructure. Within the colony volume, bacteria were oriented in a regular pattern characteristic of each strain studied. The evidence obtained relating to the ultrastructure, spatial orientation, and location of cells is sufficient for the unambiguous identification of bacterial strains and provides new information on colony architectonics.

Autotrophic synthesis of polyhydroxyalkanoates by the bacteria Ralstonia eutropha in the presence of carbon monoxide / T. G. Volova, G. S. Kalacheva, O. V. Altukhova // Applied Microbiology and Biotechnology. - 2002. - Vol. 58, Is. 5. - P675-678, DOI 10.1007/s00253-002-0941-8 . - ISSN 0175-7598

Аннотация: It has been found that the carbon monoxide (CO)-resistant strain of the hydrogen bacteria Ralstonia eutropha B5786 is able to synthesise polyhydroxy-alkanoates (PHAs) in the presence of CO under autotrophic conditions. This strain, grown on model gas mixtures containing 5-25% CO (v/v), accumulates up to 70-75% (of absolutely dry matter) PHA, without significant variation in the yield coefficient on hydrogen. No suppression of the activities of the key enzymes of PHA synthesis (?-ketothiolase, acetoacetyl-CoA-reductase, butyrate dehydrogenase and poly-3-hydroxybutyrate synthase) was recorded. The PHA synthesised is a copolymer containing mostly ?-hydroxybutyrate (more than 99 mol%) with trace amounts of ?-hydroxyvalerate. The investigated properties of the polymer (molecular weight, crystallinity, temperature characteristics) do not differ from those of the polymer synthesised on electrolytic hydrogen.
