Аннотация: Microbial polyhydroxyalkanoates (PHAs), because of their well studied complex physiology and commercial potential, are vehicles for carbon and potential storage reduction for many microbial species. Even with the wealth of studies about microbial PHAs in the scientific literature, polymer accumulation and degradation are still not comprehensively understood. Poly(3-hydroxybutyrate) (P3HB) granule formation and polymer mobility were studied here in the bacterium Ralstonia eutropha strain B5786 in autotrophic cultures. Electron microscopy studies revealed decreasing cell size concomitant with enlargement of size and number of intracellular granules, and inhibition of cell division during intracellular polymer production. Activities of key P3HB biosynthetic enzymes demonstrated correlations with each other during polymer accumulation, suggesting an intricately regulated P3HB cycle in autotrophically grown R. eutropha cells.

Заглавие : Intracellular degradation of poly-?-hydroxybutyrate in the hydrogen-oxidizing bacterium alcaligenes eutrophus

Ключевые слова (''Своб.индексиров.''): cell dimensions--degradation--hydrogen-oxidizing bacteria--poly-?-hydroxybutyrate
Аннотация: The intracellular degradation of poly-?-hydroxybutyrate (PHB) in Alcaligenes eutrophus culture was found to occur at different rates, depending on growth conditions. The degradation of PHB probably allows protein synthesis and cell growth under nonoptimal environmental conditions. The isolated native granules of poly-?-hydroxybutyrate were stable, unless they were isolated from biomass subjected to freezing-thawing treatment. Degradation of isolated granules could also be stimulated by increasing the ionic strength of the medium or adding cell-free extracts. It is anticipated that bacterial cells contain soluble factors that either stimulate or inhibit the degradation of PHB granules.

Аннотация: Polymer poly(3-hydroxybutyrate) [P(3HB)] has been used as a matrix in slow-release formulations of the herbicide metribuzin (MET). Physical P(3HB)/MET mixtures in the form of solutions, powders, and emulsions were used to construct different metribuzin formulations (films, granules, pellets, and microparticles). SEM, X-Ray, and DSC proved the stability of these formulations incubated in sterile water in vitro for long periods of time (up to 49 days). Metribuzin release from the polymer matrix has been also studied. By varying the shape of formulations (microparticles, granules, films, and pellets), we were able to control the release time of metribuzin, increasing or decreasing it. © 2016 Taylor & Francis Group, LLC.

Заглавие : Biodegradable poly-3-hydroxybutyrate as a fertiliser carrier
Место публикации : J. Sci. Food Agric. - 2016. - С. 4183-4193. - ISSN 00225142 (ISSN) , DOI 10.1002/jsfa.7621
Ключевые слова (''Своб.индексиров.''): biodegradable polymers--controlled delivery systems--fertilisers--polyhydroxyakanoates
Аннотация: BACKGROUND: Increasing use of mineral fertilisers can lead to accumulation of fertilisers in soil, water and foodstuffs. One of the approaches to preventing these problems is to develop controlled release forms of fertilisers. RESULTS: Experimental formulations of the nitrogen fertiliser urea loaded in a degradable matrix of the natural polymer poly-3-hydroxybutyrate (P3HB) in the form of films, pellets and coated granules were constructed and investigated. Nitrogen release into soil occurred as the polymer was degraded, and it was dependent on the geometry of the carrier and the amount of nitrogen loaded in it, showing that nitrogen release can last for 30 days or longer and that release rates can be controlled by varying the fabrication technique employed. P3HB/urea formulations have a favourable effect on the soil microbial community. The use of embedded urea has a beneficial influence on the growth of creeping bentgrass (Agrostis stolonifera) and lettuce (Latuca sativa) and reduces removal of nitrogen with drain water. CONCLUSION: The slow-release nitrogen formulations developed in this study can be buried in soil together with seeds preventing nitrogen deficiency. The use of such slow-release formulations can decrease the amounts of chemicals in the environment and prevent their adverse effects on the biosphere. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry

Ключевые слова (''Своб.индексиров.''): tebuconazole--poly-3-hydroxybutyrate--fungicidal effect--fusariummoniliforme--wheat plant communities--root rot
Аннотация: Fungicidal activity of experimental tebuconazole (TEB) formulations was investigated in laboratory soil ecosystems in wheat plant communities infected by Fusarium moniliforme. TEB was embedded in the matrix of poly-3-hydroxybutyrate, shaped as films and microgranules. These formulations were buried in the soil with wheat plants, and their efficacy was compared with that of commercial formulation Raxil and with the effect of pre-sowing treatment of seeds. In the experiment with the initially infected seeds and a relatively low level of natural soil infection caused by Fusarium fungi, the effects of the experimental P(3HB)/TEB formulations and Raxil were comparable. However, when the level of soil infection was increased by adding F. moniliforme spores, P(3HB)/TEB granules and films reduced the total counts of fungi and the abundance of F. moniliforme more effectively than Raxil. Seed treatment or soil treatment with Raxil solution showed an increase in the percentage of rot-damaged roots in the later stages of the experiment. In the early stage (between days 10 and 20), the percentage of rot-damaged roots in the soil with TEB embedded in the slowly degraded P(3HB) matrix was similar to that in the soil with Raxil. However, the efficacy of P(3HB)/TEB formulations lasted longer, and in later stages (between days 20 and 30), the percentage of rot-damaged roots in that group did not grow. In experiments with different TEB formulations and, hence, different fungicidal activities, the increase in plant biomass was 15-17 to 40-60% higher than in the groups where TEB was applied by using conventional techniques.

Аннотация: Slow-release fungicide formulations (azoxystrobin, epoxiconazole, and tebuconazole) shaped as pellets and granules in a matrix of biodegradable poly(3-hydroxybutyrate) and natural fillers (clay, wood flour, and peat) were constructed. Infrared spectroscopy showed no formation of chemical bonds between components in the experimental formulations. The formulations of pesticides had antifungal activity against Fusarium verticillioides in vitro. A study of biodegradation of the experimental fungicide formulations in the soil showed that the degradation process was mainly influenced by the type of formulation without significant influence of the type of filler. More active destruction of the granules led to a more rapid accumulation of fungicides in the soil. The content of fungicides present in the soil as a result of degradation of the formulations and fungicide release was determined by their solubility. Thus, all formulations are able to function in the soil for a long time, ensuring gradual and sustained delivery of fungicides.

Заглавие : Thermal, mechanical and biodegradation studies of biofiller based poly-3-hydroxybutyrate biocomposites
Место публикации : Int. J. Biol. Macromol.: Elsevier B.V., 2019. - Article in press. - ISSN 01418130 (ISSN) , DOI 10.1016/j.ijbiomac.2019.11.112
Аннотация: Biodegradable poly-3-hydroxybutyrate [P(3HB)] and natural fillers - clay, peat, and birch wood flour – were used to prepare powdered composites to form pellets and granules. Pellets were produced by cold pressing of polymer and filler powder whereas granules were produced from the powders wetted with ethanol. Characterization techniques like IR spectroscopy, differential scanning calorimetry, X-ray analysis, mechanical analysis and electron microscopy were employed to study the properties of the initial P(3HB) and fillers and the composites. Analysis of the IR spectra of the composites showed the absence of chemical bonds between the components, i.e. the composites were physical mixtures. Young's moduli of the pellets prepared from initial materials varied considerably, and the highest value was obtained for P(3HB) pellets (350 MPa). Studies of biodegradation of composite pellets and granules in the soil for 35 days showed that the residual mass of the pellets had decreased to 68% for P(3HB); 56.4% for P(3HB)/peat; 67% for P(3HB)/wood flour, and 64% for P(3HB)/clay; granules exhibited a similar mass loss, residual mass of the granules of P(3HB) was 68.4%, P(3HB)/peat 46.4%; P(3HB)/wood flour 77%, and P(3HB)/clay 74%. This shows the significance of the material as an eco-friendly composite without sacrificing its mechanical properties. © 2018

Аннотация: BACKGROUND The purpose of the present study was to develop ecofriendly herbicide formulations. Its main aim was to develop and investigate slow-release formulations of herbicides (metribuzin, tribenuron-methyl, and fenoxaprop-P-ethyl) of different structure, solubility, and specificity, which were loaded into a degradable matrix of poly-3-hydroxybutyrate (P(3HB)) blended with available natural materials (peat, clay, and wood flour). RESULTS Differences in the structure and physicochemical properties of the formulations were studied depending on the type of the matrix. Herbicide release and accumulation in soil were associated with the solubility of the herbicide. Fourier-transform infrared spectroscopy showed that no chemical bonds were formed between the components in the experimental formulations. Degradation of the formulations in agro-transformed soil in laboratory conditions was chiefly influenced by the shape of the specimens (granules or pellets) while the effect of the type of filler (peat, clay, or wood flour) was insignificant. The use of granules enabled more rapid accumulation of the herbicides in soil: their peak concentrations were reached after 3 weeks of incubation while the concentrations of the herbicides released from the pellets were the highest after 5-7 weeks. Loading of the herbicides into the polymer matrix composed of the slowly degraded P(3HB) and natural materials enabled both sustained function of the formulations in soil (lasting between 1.5 and = 3 months) and stable activity of the otherwise rapidly inactivated herbicides such as tribenuron-methyl and fenoxaprop-P-ethyl. CONCLUSION The experimental herbicide formulations enabled slow release of the active ingredients to soil. (c) 2019 Society of Chemical Industry

Аннотация: The present study addresses the herbicidal activity and biological effects of the metribuzin (MET) and tribenuron-methyl (TBM) herbicides used to control various weed species (Amaranthus retroflexus, Sinapis arvensis,andLeucanthemum maximum). The effects of the free herbicides and the herbicides embedded in granules of degradable polymer poly-3-hydroxybutyrate [P(3HB)] blended with birch wood flour were compared. Metribuzin, regardless of the form, caused 100% mortality of the three weeds by day 21. The herbicidal activity of tribenuron-methyl was lower than that of metribuzin, but the embedded TBM was superior to the free herbicide in the length and strength of its action on the weeds. Both metribuzin forms dramatically decreased the main parameters of fluorescence: maximum quantum yield of photosystem-II [Y(II)(max)], maximum quantum yield of non-photochemical quenching [Y(NPQ)(max)], and maximum rate of non-cyclic electron transport [ETRmax] and concentrations of chlorophyllaandb. The effect of the embedded TBM on the photosynthetic activity of the weeds was lower in the first two weeks of the growth of herbicide-treated plants but lasted longer than the effect of the free TBM and increased over time. Embedding of metribuzin in the matrix of degradable blend did not decrease its herbicidal activity.

Заглавие : Efficacy of Slow-Release Formulations of Metribuzin and Tribenuron Methyl Herbicides for Controlling Weeds of Various Species in Wheat and Barley Stands
Место публикации : ACS Omega: American Chemical Society, 2020. - Article in press. - ISSN 24701343 (ISSN), DOI 10.1021/acsomega.0c02492
Аннотация: The herbicidal activity of long-acting formulations of metribuzin and tribenuron methyl herbicides embedded in granules prepared from a mixture of degradable poly(3-hydroxybutyrate) and birch wood flour was studied in laboratory-grown weeds of various species and in wheat Triticum aestivum and barley Hordeum vulgare stands infested by weeds. The constructed formulations effectively suppressed all species of weeds studied. The biological effectiveness of herbicide formulations toward intact plants in wheat and barley stands infested with weeds was close to 100%, which was significantly higher than the effect of their free forms. The more effective suppression of weeds by embedded herbicides was beneficial for the growth of crops whose aboveground biomass was 8-13 to 20% greater than that of the crops in the treatments with free herbicides. Embedded metribuzin and tribenuron methyl exhibit sustained and pronounced herbicidal activity and are effective for pre-emergence soil application for crops infested with weeds of various species. © Copyright © 2020 American Chemical Society.

Аннотация: The herbicidal activity of long-acting formulations of metribuzin and tribenuron methyl herbicides embedded in granules prepared from a mixture of degradable poly(3-hydroxybutyrate) and birch wood flour was studied in laboratory-grown weeds of various species and in wheat Triticum aestivum and barley Hordeum vulgare stands infested by weeds. The constructed formulations effectively suppressed all species of weeds studied. The biological effectiveness of herbicide formulations toward intact plants in wheat and barley stands infested with weeds was close to 100%, which was significantly higher than the effect of their free forms. The more effective suppression of weeds by embedded herbicides was beneficial for the growth of crops whose aboveground biomass was 8-13 to 20% greater than that of the crops in the treatments with free herbicides. Embedded metribuzin and tribenuron methyl exhibit sustained and pronounced herbicidal activity and are effective for pre-emergence soil application for crops infested with weeds of various species.
