Abstract:

A talajok hazai és nemzetközi kutatásában egyre nagyobb szerepet kap a talajok mikrobiótájának vizsgálata. Hazai viszonylatban szikes talajokon eddig kevés ilyen irányú kutatás történt. Kutatásunkban kiskunsági szikes talajok mikrobaközösségeinek katabolikus aktivitás mintázatát vizsgáltuk Apajpusztáról származó mintákon. A mintavételhez négy, a szikesedés különböző fázisaira jellemző növényzettel rendelkező területet választottunk ki (szoloncsák vaksziknövényzet, kiskunsági szikfoknövényzet, ürmös szikespuszta és füves szikespuszta), ezek területéről a talaj mikrobiológiai szempontból legaktívabbnak tekintett 0-10 cm-es rétegét mintáztuk. A minták néhány fontosabb talajtani paraméterét meghatároztuk (szemcseösszetétel, pH, só-, humusz- és mésztartalom, valamint néhány fontosabb tápelem mennyisége). A négy eltérő növényzetű terület között a talajtani paramétereik alapján is jelentős különbségeket tapasztaltunk. A minták mikrobiológiai aktivitását az itthon még kevéssé ismert mikrorespirációs (MicroRespTM) módszerrel vizsgáltuk. Ennek során a talajmintákhoz 23 különböző szerves szubsztrátot adtunk, és az általuk indukált légzési válaszon keresztül mértük, hogy az egyes talajminták mikrobaközösségei milyen mértékben képesek hasznosítani az egyes szubsztrátokat. Az így kapott, közösségre jellemző katabolikus aktivitás mintázatokat főkomponens elemzéssel és kanonikus korreszpondancia elemzéssel értékeltük. Eredményeink alapján a mikrorespirációs módszer egyértelműen alkalmas az általunk vizsgált talajok mikrobiótájának elkülönítésére. Az egyes minták katabolikus aktivitás mintázatai közötti különbségek egybevágtak a minták közötti, talajfizikai és —kémiai tulajdonságban megfigyelt eltérésekkel. A kutatást az OTKA (K 108572) támogatta.

Abstract:

Plant invasions have become one of the biggest threats to natural ecosystems across the globe during the last decade, and there is growing interest in their effect on the native flora and biota in invaded areas. However, little is known about their effect on soil microbial communities, especially non-fungal communities, in harsh environments such as a sand-dune ecosystem. The objective of this study, conducted in the northern Sharon sand-dune area of Israel, was to investigate the influence of the invasive alien plant Heterotheca subaxillaris on a sand-dune microbial community. Soil samples were collected under the canopies of the invasive plant, a native plant (Artemisia monosperma), and from bare areas at two sites, at different distances from the seashore going inland during the wet and dry seasons. MicroRespTM system methodology provided data on microbial biomass, basal respiration, and the community-level physiological profile (CLPP) at the community level, in addition to abiotic components, e.g., soil moisture, organic matter, conductivity, and pH. The microbial community in the soil samples found under the canopy of H. subaxillaris was less active and exhibited significantly lower CLPP, microbial biomass, and basal respiration than in the A. monosperma (native plant) samples. Soil abiotic variables were strongly affected by seasonality, sites, and were related to plant cover and the ecophysiological adaptation of each one. This study emphasizes the threat to soil microbial communities induced by plant invasion, especially in unique and harsh sand-dune ecosystems. This threat might also affect other organisms living in this fragile environment.

Abstract:

MicroResp is a colorimetric method developed by Campbell et al., (2003), used for assessing the community level physiological profile of the microbial population. MicroResp can be used to assess soil health, pollution induced community tolerance, also for toxicity testing, pesticide degradation profiles, bioremediation evaluation and water ecology and toxicity. The aim of the present review was to look over the results of recent papers and to highlight the importance and efficiency of the MicroResp method in assessing the physiological profile of the microbial community. The method advantages and limitations were also assessed. We focused on agricultural soil in order to deepen our understanding about changes of microbial community induced by agricultural practices. To achieve this goal, academic literature was analyzed using an academic database. There were set a total of six keywords, used to make a search algorithm, achieving five search terms. For each search, the first four articles of interest were chosen to be reviewed. After the searches for each of the terms, between 72 and 210 articles were found, 20 of them being chosen for final evaluation. Following the undertaken research, it can be stated that MicroResp method is an important tool to assess the physiological profile of the microbial community, featuring a series of advantages that place it ahead of other competing methods.

Abstract:

E tanulmány célja egy martonvásári hosszútávú tartamkísérlet trágyázás nélkül művelt kukorica monokultúra talajában fellelhető baktériumközösségek filogenetikai diverzitásának és anyagcsere potenciáljának a felmérése volt. A kutatás során NGS és MicroResp™ technikával vizsgáltuk a művelt és a természeteshez közeli állapotú talajok mikrobiális jellemzőit.Az NGS adatai alapján a kukorica monokultúra szántott rétegének mintáinak baktériumközösség szerkezete nagyfokú hasonlóságot mutatott egymással, és elkülönült a löszpusztagyep A és C rétegéből formálódó csoporttól, míg a kukorica monokultúra C szintjéből származó minta élesen elvált a többitől. A gyepek talajában nem találtunk nagyobb bakteriális taxonómiai diverzitást, mint a művelt talajokban.A MicroResp™ mérés alapján megállapítottuk, hogy a természeteshez közeli állapotú talajok felszínhez közeli (A) rétegében kiugró a mikrobiális aktivitás mértéke. A kukorica monokultúrából származó A szint minták mikrobiális aktivitási mintázata egymáshoz hasonló volt, a C rétegből származó minták külön csoportot képeztek.Eredményeink alapján tehát a hosszú távú tartamkísérletbe vont művelt talajok baktériumközösségeinek filogenetikai diverzitása és metabolikus potenciálja jelentősen eltért a löszpusztagyep mintákétól.

Abstract:

Agricultural practices, such as the use of fertilizers, can change the structure and function of soil microbial community. Monitoring and assessing the soil microbiota and its dynamics related to different factors can be a powerful tool for understanding basic and applied ecological contexts. The main objective of this paper was to assess the changes of carbon turnover rate and the microbial metabolic activity, when different types of fertilizers were used, process called priming effect. A microcosm experiment was designed and performed under controlled temperature and humidity and the soil samples were analyzed using the MicroResp technique. Results show that the integration in soil of different carbon sources, such as green manure, can lead to a positive priming effect and integration of mineral fertilizers can lead to negative priming effect. The carbon sources with the highest respiratory activity were α-ketoglutaric acid, malic acid, oxalic acid, citric acid, while the lowest respiratory activity was obtained in case of arginine.

Abstract:

Despite the high level of adoption of genetically modified (GM) cultivars in the Australian cotton production system, concerns remain over the use of GM technology, particularly with regard to potential non-target effects. To address the hypothesis that GM cotton causes shifts in rhizosphere microbial diversity or function, we assessed rhizosphere soil samples from a range of conventional and GM cotton cultivars for diversity of bacteria and fungi, populations of ammonium oxidisers, rhizosphere basal and selective substrate-induced respiration, and non-symbiotic N2 fixation and nitrification. Comparison of results for GM and conventional cotton cultivars, both between and within seasons, indicated that the cotton rhizosphere plant–microbial interactions are variable in nature and significantly influenced by cultivar type. The GM status of the plant did not result in rhizosphere bacterial or fungal DNA-based grouping, but MicroResp data did show some grouping based on GM status, although this was not consistent by trait, suggesting that the GM trait is not greater than cultivar selection in causing rhizosphere change, especially when measured in the field environment with all the associative management practices.

Abstract:

In this study, we examined the effect of salinity and alkalinity on the metabolic potential and taxonomic composition of microbiota inhabiting the sodic soils in different plant communities. The soil samples were collected in the Pannonian steppe (Hungary, Central Europe) under extreme dry and wet weather conditions. The metabolic profiles of microorganisms were analyzed using the MicroResp method, the bacterial diversity was assessed by cultivation and next-generation amplicon sequencing based on the 16S rRNA gene. Catabolic profiles of microbial communities varied primarily according to the alkali vegetation types. Most members of the strain collection were identified as plant associated and halophilic/alkaliphilic species of Micrococcus, Nesterenkonia, Nocardiopsis, Streptomyces (Actinobacteria) and Bacillus, Paenibacillus (Firmicutes) genera. Based on the pyrosequencing data, the relative abundance of the phyla Proteobacteria, Actinobacteria, Acidobacteria, Gemmatimonadetes and Bacteroidetes also changed mainly with the sample types, indicating distinctions within the compositions of bacterial communities according to the sodic soil alkalinity-salinity gradient. The effect of weather extremes was the most pronounced in the relative abundance of the phyla Actinobacteria and Acidobacteria. The type of alkali vegetation caused greater shifts in both the diversity and activity of sodic soil microbial communities than the extreme aridity and moisture.

Abstract:

Nowadays, one of the most important challenges is to ensure sustainable agricultural management of crops such as maize (Zea mays L.). Long-term crop production, however, may influence the soil properties, the composition and activity of microbial communities. The aim of this study was to compare the catabolic activity and taxonomic diversity of bacterial communities inhabiting the soil of a non-fertilized maize monoculture and a natural grassland. Samples were taken from the horizons A and C in the first part of the vegetation period. MicroResp™ technique was used to explore the catabolic potential of microbial communities and next generation amplicon sequencing to reveal the bacterial diversity. Based on the catabolic activity results, higher differences were revealed among the soil horizons than the different land uses. The highest degree carbon source utilization was detected in the soil horizon A of the natural grassland. The taxonomic composition of bacterial communities was dominated by Proteobacteria. The relative abundance of other dominant phyla (Acidobacteria, Bacteroidetes, Verrucomicrobia, Actinobacteria, Planctomycetes, Gemmatimonadetes, Chloroflexi and Patescibacteria) varied according to both the land use and soil depth. Amplicon sequences belonging to genera of r-strategist “copiotrophic” and K-strategist “oligotrophic” bacteria were identified from the soils of both maize monoculture and grassland.

Full text

Abstract:

Effects of bovine urine on microbial functional attributes within the carbon (C) cycle have not previously been investigated. The magnitude of urine effects on microbial populations may be mediated by the ability of a soil to buffer changes to pH and electrical conductivity (EC) in response to urine. We examined changes in the metabolism of C substrates by microbial communities subsequent to treatment with dairy cow urine in 27 dairy grazed soils across four soil orders. Untreated soils (baseline) and soil treated with urine or water were incubated (25°C) for 21 days then assessed for microbial function using MicroResp™. Urine addition decreased functional capacity, microbial diversity, and microbial biomass C at 21 days after urine addition, but did not affect basal respiration, compared with the water control. Urine addition also led to a shift in community-level physiological profiles. There were no indirect effects of soil pH or EC buffering capacity on the functional microbial parameters measured. Urine addition increased the utilisation of urea and may be a factor in losses of fertiliser nitrogen in dairy systems. The length of time that urine depresses catabolic function could have important implications for long-term soil organic matter cycling under urine patches.

Abstract:

Microbial communities in agricultural ecosystems are characterized by a strong dynamic and radical change due to technological inputs applied. Corn is cultivated on large areas with high requirements for nutrients and an increased potential for activation of specific microbial groups. The aim of this study was to assess the unilateral and synergic effect of zeolite and mineral fertilizers on the development and transformation of microbial functional groups in the rhizosphere of corn. Physiological profile assessment of microbial communities has been carried out on the basis of substrate induced respiration, monitored over a period of 6 hours of incubation. The amount of CO2 registered in Microresp plates represents the activity of functional groups in decomposition of each type of substrate applied. Characteristic groups of microorganisms in maize rhizosphere are capable of decomposing acids: citric, L-malic, oxalic and α-Ketoglutaric. These substrates indicate the presence of high concentrations of organic matter in soil and the existence of a biological crust on the surface (citric acid), respectively the existence of powerful processes for the decomposition of organic material by actinomycetes (α-Ketoglutaric acid). The highest microbial activities were observed in groups of bacteria involved in processes of plant growth promotion and microbial groups with an important role in the processes of denitrification (oxalic acid). For the application of urea a triple value of activity of this type of microflora is observed. Functional groups codominant in soils cultivated with corn are specialized in efficient degradation of organic matter and biological crust, zeolite providing the complex substrate necessary for the development of these microorganisms.

Abstract:

Plant rhizosphere is the portion of soil which is in direct contact with the plant roots. From the microbiological point of view, this area is characterized by strong dynamic of functional groups with high specificity towards the substrate available. Spring barley is a crop with high requirements to the composition of the microflora in the rhizosphere, disturbances produced by agronomic inputs affecting the stability of rhizospheric contact interfaces and ultimately the plant growth. Analysis of changes within the microbial community was carried out with the purpose of defining the disruptive impact of mineral inputs and potential of zeolite to reduce these disruptions. Microbial functional groups were analyzed on the basis of the CO2 export under the specific conditions of soil inoculation on specific substrates over a time period of incubation. Microresp detection plates allow evaluation of a large number of samples under identical conditions of inoculation and the establishment of dynamics of the entire microbial community. The dynamics of the entire microbial communities (basal respiration) is stimulated to increase in case of unilateral application of zeolite and zeolite as a buffer for urea fertilization. General growth trend of microbial communities follows proportional the associated application of zeolite with urea, the most powerful non-symbiotic nitrogen fixation processes being stimulated by this combination of fertilizers. Simultaneously, an increase in the dynamics of denitrifiers was observed, also the decomposition of lignin and cellulose and biological crust formation due to the proliferation of cyanobacteria. Rhizosphere of barley plants is characterized by the presence of actinomycetes as dominant in functional microbial community of all experimental variants analyzed with a high capacity for biological degradation and raised mineralization of organic matter.

Abstract:

Plant communities and fertilization may have an impact on soil microbiome. Most commercial olive trees are minerally fertilized, while this practice is being replaced by the use of organic amendments. Organic amendments can both fertilize and promote plant growth-promoting organisms. Our aims were (i) to describe the changes in soil bacterial and fungal communities induced by the presence of young olive trees and their interaction with organic amendments and (ii) to compare the effects of mineral and organic fertilization. We set up two parallel experiments in pots using a previously homogenized soil collected from a commercial olive orchard: in the first one, we grew olive saplings in unamended and organically amended soils with two distinct composts and compared these two soils incubated without a plant, while in the second experiment, we comparatively tested the effects of organic and mineral fertilization. OTUs and the relative abundances of bacterial and fungal genera and phyla were analyzed by 16S rRNA and ITS1 gene amplicon using high-throughput sequencing. Basal respiration and substrate-induced respiration were measured by MicroRespTM. The effects of the different treatments were analyzed in all phyla and in the 100 most abundant genera. The presence of olive saplings increased substrate-induced respiration and bacterial and fungal richness and diversity. Organic amendments greatly affected both bacterial and fungal phyla and increased bacterial richness while not affecting fungal richness. Mineral fertilization increased the relative abundance of the less metabolically active bacterial phyla (Actinobacteria and Firmicutes), while it reduced the most metabolically active phylum, Bacteroidetes. Mineral fertilization increased the relative abundance of three N2-fixing Actinobacteria genera, while organic fertilization only increased one genus of Proteobacteria. In organically and minerally fertilized soils, high basal respiration rates were associated with low fungal diversity. Basidiomycota and Chytridiomycota relative abundances positively correlated with basal respiration and substrate-induced respiration, while Ascomycota correlated negatively. Indeed, the Ascomycota phyla comprised most of the fungal genera decreased by organic amendments. The symbiotrophic phylum Glomeromycota did not correlate with any of the C sources. The relative abundance of this phylum was promoted by the presence of plants but decreased when amending soils with composts.

Abstract:

Abstract Soils play an important role in the ecosystem of karstic landscapes both as a buffer zone and as a source of acidity to belowground water. Although the microbiota of karstic soils is known to have a great effect on karstification processes, the activity and composition of these communities are largely unknown. This study gives a comparative analysis of soil microbial profiles from different parts of a doline located at Aggtelek, Hungary. The aim was to reveal the relationships between the vegetation type and genetic fingerprints and substrate utilisation (multi-SIR) profiles of the soil microbiota. Soil samples were collected in early and late springs along a transect in a doline covered with different types of vegetation. Genetic fingerprints of bacterial communities were examined by denaturing gradient gel electrophoresis (DGGE) based on the 16S rRNA gene, along with multi-SIR profiles of the microbial communities measured by the MicroResp method using 15 different carbon sources. Genetic fingerprinting indicated that vegetation cover had a strong effect on the composition of soil bacterial communities. Procrustean analysis showed only a weak connection between DGGE and multi-SIR profiles, probably due to the high functional redundancy of the communities. Seasonality had a significant effect on substrate usage, which can be an important factor to consider in future studies.
