Wheat growth on neutral and soil-like substrates: Carbon dioxide exchange and microflora / J. -B. Gros [et al.] // Acta Horticulturae. - 2004. - Vol. 644. - P243-248
Кл.слова (ненормированные):
Carbon dioxide -- Closed ecological system
Аннотация: The soil-like substrate (SLS), which is a potential candidate for employment in closed ecological systems, has been tested. CO2 exchange, composition and numbers of soil microflora have been examined in .wheat-SLS. system. The results produced have been compared to analogous characteristics of .wheat-neutral substrate. system. A hydroponic method was used under wheat growing on the neutral substrate (expanded clay aggregate). Plants for both studies were grown in closed environment from seed to physiological maturity. In the .wheat-SLS. system, the net photosynthetic rate of canopy was positive in the course of 6.55 days after planting. The net photosynthetic rate of canopy in .wheat-neutral substrate. system was positive in the entire course of vegetation. According to calculations in the course of vegetation, photosynthesis has withdrawn 3.28 kg m-2 CO2 from the .wheat-SLS. system and 3.40 kg m-2 CO2 from the .wheat-neutral substrate. system. On the SLS dominant among bacteria were the spore-forming bacteria from Bacillus genus, among fungi . from Trichoderma genus. In the hydroponic cultivation on neutral substrate dominant were bacteria from Pseudomonas genus, most commonly found fungi were species from Fusarium and Botrytis genera.

Аннотация: We studied soil-like substrate (SLS) as a potential candidate for plant cultivation in bioregenerative life support systems (BLSS). The SLS was obtained by successive conversion of wheat straw by oyster mushrooms and worms. Mature SLS contained 9.5% humic acids and 4.9% fulvic acids. First, it was shown that wheat, bean and cucumber yields as well as radish yields when cultivated on mature SLS were comparable to yields obtained on a neutral substrate (expanded clay aggregate) under hydroponics. Second, the possibility of increasing wheat and radish yields on the SLS was assessed at three levels of light intensity: 690, 920 and 1150 ?mol m-2 s-1 of photosynthetically active radiation (PAR). The highest wheat yield was obtained at 920 ?mol m-2 s-1, while radish yield increased steadily with increasing light intensity. Third, long-term SLS fertility was tested in a BLSS model with mineral and organic matter recycling. Eight cycles of wheat and 13 cycles of radish cultivation were carried out on the SLS in the experimental system. Correlation coefficients between SLS nitrogen content and total wheat biomass and grain yield were 0.92 and 0.97, respectively, and correlation coefficients between nitrogen content and total radish biomass and edible root yield were 0.88 and 0.87, respectively. Changes in hormone content (auxins, gibberellins, cytokinins and abscisic acid) in the SLS during matter recycling did not reduce plant productivity. Quantitative and species compositions of the SLS and irrigation water microflora were also investigated. Microbial community analysis of the SLS showed bacteria from Bacillus, Pseudomonas, Proteus, Nocardia, Mycobacterium, Arthrobacter and Enterobacter genera, and fungi from Trichoderma, Penicillium, Fusarium, Aspergillus, Mucor, Botrytis, and Cladosporium genera.

Аннотация: More than 200 Trichoderma isolates were obtained from soil in various forests in Middle Siberia. Four species Trichoderma anamorph Hypocrea gelatinosa, T. viride, T. virens, and T. longibrachiatum were identified at the first stage following descriptions of Bissett. Four isolates were selected for disease suppressiveness test. Isolates were tested for antibiotic activity against Fusarium fungi, as major pathogens of spruce and pine seedlings. All tested Trichoderma isolates showed high or moderate activity against Fusarium species. This supported the conclusion that selected strains have a potential to be used for biocontrol of coniferous seedlings pathogens.

Аннотация: The integrated study addressing biodegradation of microbial linear polyesters of hydroxyalkanoic acids (polyhydroxyalkanoates, PHAs) in tropical conditions by microbial communities of Vietnamese soils was performed in locations close to Hanoi and Nha Trang, which differed in their weather conditions and microbial communities. It shows that PHA degradation in tropical soils is influenced by polymer chemical composition, specimen shape, and microbial characteristics. The homopolymer of 3-hydroxybutyric acid is degraded at higher rates than the copolymer of 3-hydroxybutyric and 3-hydroxyvaleric acids. The average rates of mass loss were 0.04-0.33% per day for films and 0.02-0.18% for compact pellets. PHA degradation was accompanied by a decrease in the polymer molecular mass and, usually, an increase in the degree of crystallinity, suggesting preferential degradation of the amorphous phase. Under the study conditions, representatives of the bacterial genera Burkholderia, Bacillus, Cupriavidus, Mycobacterium, and Nocardiopsis and such micromycetes as Acremonium, Gongronella, Paecilomyces, and Penicillium, Trichoderma have been identified as major PHA degraders.

Аннотация: The effect of high temperatures (35 and 45 degreesC) on microflora of the root zone of radish plants grown in phytotron was evaluated by the response of microorganisms from 9 indicator groups. Phytotron air temperature elevated to 35 degreesC for 20 hours caused no significant changes in qualitative and quantitative composition of the root microflora in experimental plants. By the end of the experiment, the species diversity of microflora had changed. The amount of phytopathogenic microorganisms decreased which can be interpreted as more stable co-existence of microflora with plants. The numbers of microbes from other indicator groups was in dynamic equilibrium. The plants' condition did not deteriorate either. Exposure to the temperature of 45 degreesC for 7 hours have been found to change the numbers and species diversity in the radish root zone microflora. The microorganisms were observed to increase their total numbers at the expense of certain indicator groups. Bacteria increased spore forms at the stage of spores. Colon bacillus bacteria of increased their numbers by the end,of experiment by an order. By the end of experiment the roots of experiment plants had microscopic fungi from. Mucor, Aspergillus, Trichoderma, Cladosporium genera. The observed changes in the microbial complex seem to be associated with the changes of root emissions and general deterioration of the plants' condition. It is suggested that the response of the microorganisms can be indicative of the condition of plants under investigation. (C) 2002 Published by Elsevier Science Ltd on behalf of COSPAR.

Аннотация: Biodegradation of film specimens from polyhydroxyalkanoates (PHAs) of two types - poly-3-hydroxybutyrate (PHB) and poly-3-hydroxybutyrate-co-3- hydroxyvalerate (PHBV) - was analysed in different environments: tropical sea waters of the South China Sea (Nha Trang, Vietnam) and soils in the environs of Hanoi (Vietnam), Nha Trang (Vietnam) and Krasnoyarsk (Siberia, Russia). In seawater, the mass loss of the specimens of both types was almost equal. However, in tropical soils, PHB degraded quicker than PHBV. In the Siberian soil, the degradation rate of the PHBV was generally higher than that of PHBV. Analysis of molecular mass of PHA specimens showed its decreasing during biodegradation. In the tropical sea conditions, PHA degrading microorganisms were represented by bacteria of Enterobacter, Bacillus and Gracilibacillus genera. Among PHA degrading bacteria, Burkholderia, Alcaligenes, Bacillus, Mycobacterium and Streptomyces genera were identified in Vietnamese soils, and Variovorax, Stenotrophomonas, Acinetobacter, Pseudomonas, Bacillus and Xanthomonas genera in Siberian soils. Micromycetes of Gongronella, Paecilomyces, Penicillium and Trichoderma genera exhibited PHA degrading activity in Vietnamese soils, and Paecilomyces, Penicillium, Acremonium, Verticillium and Zygosporium genera - in Siberian soils.

Аннотация: The application of nanobiotechnology is an emerging area of nanoscience and nanotechnology. Nanodi-amond has been a potent antibacterial, antifungal, antioxidant, and antiplatelet agent. In the present study, nanodiamonds were reduced by green synthesis and characterization was done through SEM, TEM, FTIR, and XRD. Further they were tested for their biological applications. The antimicrobial activity was investigated/studied/examined? through well diffusion method. The best activity was observed against Trichoderma reesei (16 mm) at 140 ?g/ml. The antioxidant activity was investigated through DPPH and FRAPS method. It was observed that the biologically reduced nanodiamonds reduce the Fe3+ ions to Fe2+ ions at 600 mM/l/g concentration. In DPPH assay, inhibitory concentration was found to be 4.58 ?g/ml. Further the antiplatelet activity was investigated by prothrombin time (PT) and activated partial throm-boplastin time (APTT) assay, and it was observed that biologically reduced nanodiamonds have potent an-tiplatelet activity. © 2021 Sumy State University
