Fine chloroplast structure in cucumber and pea leaves developed under red light / E. N. Zavorueva [et al.] // Russian Journal of Plant Physiology. - 2000. - Vol. 47, Is. 6. - P740-747 . - ISSN 1021-4437
Кл.слова (ненормированные):
Cucumis sativus -- Pigments -- Pisum sativum -- Red light -- Ultrastructure
Аннотация: Photosynthetic activity, the content of various photosynthetic pigments, and the chloroplast ultrastructure were examined in the leaves of cucumber (Cucumis sativus L.) and pea (Pisum sativum L.) plants of different ages grown under red light (600-700 nm, 100 W/m2). In pea leaves tolerant to red-light irradiation, chloroplast ultrastructure did not essentially change. In the first true leaves of cucumber plants susceptible to red-light irradiation, we observed a considerable increase in the number and size of plastoglobules, the appearance of chloroplasts lacking grana or containing only infrequent grana, and stromal thylakoids. In the upper leaves of 22-day-old cucumber plants, the chloroplast structure was essentially similar to that of the control chloroplasts in white light, and we therefore suppose that these plants have acclimated to red light.

Investigation of culture heterogeneity of the hydrogen-oxidizing bacterium Alcaligenes eutrophus / G. N. Stasishina [et al.] // Microbiology. - 1999. - Vol. 68, Is. 2. - P164-170 . - ISSN 0026-2617
Кл.слова (ненормированные):
Dissociation -- Heterogeneity -- Hydrogen-oxidizing bacteria -- Ultrastructure of cells and colonies
Аннотация: Some morphological, physiological, and biochemical manifestations of heterogeneity in the population of the hydrogen-oxidizing bacterium Alcaligenes eutrophus Z1 were studied. The population dissociated into R and S variants differing in the size, appearance, and architectonics of colonies, cell ultrastructure, growth rate, enzyme activity, and chemical composition. Heterogeneity also manifested itself in different responses of cells to antibiotics, surfactants, and elevated temperature. В© 1999 MAHK "Hayka/Interperiodica".

Transfer of xenobiotics through cell membranes of luminous bacteria / S. E. Medvedeva // Luminescence. - 1999. - Vol. 14, Is. 5. - P267-270 . - ISSN 1522-7235

Аннотация: The influence of some chemical substances on luminous bacteria was studied to elucidate the interrelation between the xenobiotics action on bacterial luminescence and cell ultrastructure. Such substances as quinones, phenols, chlorides of heavy metals (in concentrations of substances inhibiting luminescence by 50%) resulted in damaging effects upon bacteria: a lot of cells had damage of membranes due to changes in their permeability. It was found that the high concentration of EDTA and toluene decreased the luminescence and caused the condensation of DNA-fibrils and the cell damage after long-term and short-term action. The low concentration of EDTA and toluene did not decrease the bacterial luminescence; the noticeable damage of cell membranes did not take place during short-term treatment. However, the long action of these substances changed the membrane permeability resulting in increased sensitivity of bacterial luminescence to some toxic substances.

Growth and luminescence of luminous bacteria promoted by agents of microbial origin. / E. K. Rodicheva [et al.] // Journal of bioluminescence and chemiluminescence. - 1993. - Vol. 8, Is. 6. - P293-299 . - ISSN 0884-3996

Аннотация: The examination of four species of luminous bacteria Photobacterium leiognathi, Photobacterium phosphoreum, Vibrio fischeri and Vibrio harveyi has enabled us to reveal some nutrient medium components effecting growth, luminescence intensity and luciferase synthesis. These agents are nucleic components (nucleotides, nucleotides and amine bases), amino acids and vitamins, which are part of hydrolysates from the biomass of various lithotrophic microorganisms, hydrogen-oxidizing, iron-oxidizing and carboxydobacteria. The effect of promoting agents essentially alters the physiological state and ultrastructure of the cells of luminous bacteria and increases luciferase biosynthesis two- to three-fold compared to a control.

Аннотация: Growth of Seliberia carboxydohydrogena was inhibited by CO at 10 to 40% (v/v), resulting in increased substrate utilization and enhanced synthesis of cytochromes and cyclopropane and saturated fatty acids. The bacteria showed increased formation of new membrane structures, with pronounced folding of their cell walls. В© 1993 Rapid Communications of Oxford Ltd.

Immunoelectronmicroscopic study of the nucleoid structure of hydrogen bacteria. / O. A. Mogilnaya [et al.] // Journal of Basic Microbiology. - 1992. - Vol. 32, Is. 6. - P381-387 . - ISSN 0233-111X

Аннотация: Electron microscopical studies of the nucleoid structure of hydrogen bacteria using ultrahin sections and spread DNA from bacterial cell lysates revealed a different DNA packaging in the cell. A compact state of the major part of DNA at all growth stages and stability of nucleosome-like structures were shown. The use of antibodies to HU protein of E. coli labelled by protein A-colloidal gold demonstrated the immunological relationship between HU protein of E. coli and histone-like proteins of Alcaligenes eutrophus and their possible role in the nucleosome-like DNA packaging in procariotic genome.

Bioluminescent method in studying the complex effect of sewage components / D. I. Stom [et al.] // Archives of Environmental Contamination and Toxicology. - 1992. - Vol. 22, Is. 2. - P203-208 . - ISSN 0090-4341

Аннотация: The inhibition of bacterial luminescence has been used in testing industrial enterprises sewage. The toxicity of the sewage is less than the total toxicity of separate components due to neutralization of quinone products of polyphenol oxidation in the reactions with the other phenol components of sewage. Toxicity increase is due to their influence on the cell membrane. Studies of cell ultrastructure confirm this fact. The studied mechanism of the complex effect allowed a more accurate forecast of the ecological situation during the discharge of phenol compounds and metals. It also showed the necessity of taking into account the complex effect of sewage components on contaminant discharge into water reservoirs.

Colony structure of a consortium of nitrifying bacteria / A. P. Puzyr' [и др.] // Mikrobiologiya. - 2001. - Vol. 70, Is. 1. - P. 98-105 . - ISSN 0026-3656
Кл.слова (ненормированные):

Аннотация: Colonies produced by a consortium of nitrifying bacteria were studied using light and electron microscopy. The colonies were obtained by direct plating of inoculum from a two-stage nonsterile chemostat fermentor and by repeatedly passing the microbial community of the fermenter through selective media containing ammonium or nitrite. The colonies studied can be characterized by a specific combination of six types of cells differing in their ultrastructure and spatial location within the colony. The types of cells occurring within a given colony were found to depend on the nitrogen compound present in the medium. As a result of our study, morphological features of colonial bacterial communities were preliminarily identified. The proposed approach can be viewed as a method to describe microbial associations and communities.

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.
