Effect of volatile metabolites of dill, radish and garlic on growth of bacteria [Text] / L. S. Tirranen [et al.] // Acta Astronaut. - 2001. - Vol. 49, Is. 2. - P. 105-108, DOI 10.1016/S0094-5765(01)00006-6. - Cited References: 2 . - ISSN 0094-5765

Аннотация: In a model experiment plants were grown in sealed chambers on expanded clay aggregate under the luminance of 150 W/m(2) PAR and the temperature of 24 degreesC. Seven bacterial strains under investigation, replicated on nutrient medium surface in Petri dishes, were grown in the atmosphere of cultivated plants. Microbial response was evaluated by the difference between colony size in experiment and in control. In control, bacteria grew in the atmosphere of clean air. To study the effect of volatile metabolites of various plant on microbial growth, the experimental data were compared with the background values defined for each individual experiment. Expanded clay aggregate, luminance, temperature and sealed chamber (without plants) for the background were the same. Volatile metabolites from 28-days old radish plants have been reliably established to have no effect on the growth of microbes under investigation. Metabolites of 30-days old dill and 50-days old garlic have been established to have reliable bacteriostatic effect on the growth of three bacterial strains. Dill and garlic have been found to have different range of effects of volatile substances on bacterial growth. Volatile metabolites of dill and garlic differed in their effect on the sensitivity spectrum of bacteria. An attempt has been made to describe the obtained data mathematically.

Аннотация: Plants in experiments on "man-higher plants" closed ecosystem (CES) have been demonstrated to have inhibited growth and reduced productivity due to three basic factors: prolonged usage of a permanent nutrient solution introduction into the nutrient medium of intra-system gray water, and closure of the system. Gray water was detrimental to plants the longer the nutrient solution was used. However, higher plant growth was mostly affected by the gaseous composition of the CES atmosphere, through accumulation of volatile substances. (C) 1997 COSPAR. Published by Elsevier Science Ltd.

The role of volatile metabolites in microbial communities of the LSS higher plant link / L. S. Tirranen, I. I. Gitelson // Advances in Space Research. - 2006. - Vol. 38, Is. 6. - P1227-1232, DOI 10.1016/j.asr.2006.02.038 . - ISSN 0273-1177

Аннотация: The paper addresses the possibility of controlling the microbial community composition through metabolites produced by microbes. The comparative analysis of experimental data has shown that volatile metabolites make a much greater contribution to the microbial interactions than nonvolatile ones. It has been found that interaction of microorganisms via the volatiles they release occurs frequently and is typical of a number of microorganisms. Volatile metabolites released by microorganisms produce an inhibitory, sometimes bactericidal, effect on the vital functions of bacteria. The stimulating action occurs 6-8 times less frequently. The range of action on the growth of the test cultures and the range of sensitivity to the effect of volatile metabolites of the study microbes have been found to be individual. Comparative cluster analysis of the ranges of action of 100 study cultures has shown that in the investigated set of microorganism species interaction was performed via a set of volatiles of an inhibiting action (82) and of a stimulating action (52). It has been found that release of volatile metabolites by the studied microorganisms depends upon the culture age, concentrations of components of the nutrient medium, and volatile by-products released by other microorganisms. This production can be increased or decreased by the action of volatile metabolites of other microbes. This is related to strain features and culture age. The prospects of using these regulating metabolites depend on the "range", specificity and safety for other members of the microbial community in insufficient concentrations. Volatiles produced by plants and microorganisms as well as by other components of the system - humans and processing equipment installed inside the closed ecosystem - could influence the formation not only of the microbial community but also of the gas composition of the system's atmosphere, through which they could affect the state of the plants. Specially performed experiments have shown that volatile metabolites of microorganisms can accumulate in their habitat, dissolve in the atmospheric water, and maintain their biological activity for days. It has been determined that volatile metabolites of some microorganisms are toxic for plants. Growth of seedling roots is inhibited more than growth of stems. В© 2006 COSPAR.

Volatile Metabolites and External CO2 Exchange of Wheat Cenoses under Optimal Conditions and Thermal Stress / I. I. Gitel'zon [и др.] // Prikladnaya Biokhimiya i Mikrobiologiya. - 2002. - Vol. 38, Is. 1. - С. 95 . - ISSN 0555-1099
Аннотация: The effects of elevated temperature (35 and 45В°C) on photosynthesis, respiration, and both the qualitative and quantitative compositions of volatile emissions (VE) of wheat (Triticum aestuvum L. cultivar 232) cenoses at light intensities of 70, 150, or 240 W/m2 of photosynthetically available radiation (PAR) were studied. At a PAR of 240 W/m2, the thermal stabilities of photosynthesis and respiration increased at 35В°C and decreased at 45В°C. Elevated temperatures nonuniformly changed the rates and direction of VE syntheses. In this process, the highest increase in VE evolution was observed at 70 W/m2; the lowest, at 240 W/m2 and 35В°C. In addition, the concentrations and composition of VE during the repair period differed from the initial values.

Volatile metabolites of higher plant crops as a photosynthesizing life support system component under temperature stress at different light intensities / I. I.

Аннотация: The effect of elevated temperatures of 35 and 45В°C (at the intensities of photosynthetically active radiation 322, 690 and 1104 ?mol-m-2-s-1) on the photosynthesis, respiration, and qualitative and quantitative composition of the volatiles emitted by wheat (Triticum aestuvi L., cultivar 232) crops was investigated in growth chambers. Identification and quantification of more than 20 volatile compounds (terpenoids - ?-pinene, ?3 carene, limonene, benzene, ?-and transcaryophyllene, ?- and ?-terpinene, their derivatives, aromatic hydrocarbons, etc.) were conducted by gas chromatograph/mass spectrometry. Under light intensity of 1104 ?mol-m-2-s-1, heat resistance of photosynthesis and respiration increased at 35В°C and decreased at 45В°C. The action of elevated temperatures brought about variations in the rate and direction of the synthesis of volatile metabolites. The emission of volatile compounds was the greatest under a reduced irradiation of 322 ?mol-m-2-s-1 and the smallest under 1104 ?mol-m-2-s-1 at 35В°C. During the repair period, the contents and proportions of volatile compounds were different from their initial values, too. The degree of disruption and the following recovery of the functional state depended on the light intensity during the exposure to elevated temperatures. The investigation of the atmosphere of the growth chamber without plants has revaled the substances that were definitely technogenic in origin: tetramethylurea, dimethylsulfide, dibutylsulfide, dibutylphthalate, and a number of components of furan and silane nature.
