There is ample evidence that microbial processes can exhibit large variations in activity on a field scale. However, very little known about the spatial distribution of communities mediating these processes. Here we used geostatistical modelling to explore patterns size and denitrifying community, functional guild involved N-cycling, grassland subjected different cattle grazing regimes. We observed non-random pattern denitrifier community estimated by quantification denitrification genes...
Several studies have shown that plants can absorb various micropollutants. The behavior of micropollutants from wastewater treatment plant resources was comprehensively investigated in raised beds which either a mixture vegetables or maize grown. were irrigated with treated enriched sewage sludge composted sludge. Over the year, samples wastewater, water drained beds, soils and analyzed. Of seventy-five analyzed substances, fifty-four, thirty-three twenty-seven quantified sludge,...
Guano is a typical deposit found in caves derived from the excretions of bats and minor cases birds. These organic deposits decompose form series acid fluids gases that can interact with minerals, sediments, rocks present cave. Over sixty phosphates are known described caves, but guano decay also often leads to formation nitrates sulfates. In this study twenty-two European were investigated for their guano-related secondary minerals. Using various analytical techniques, seventeen phosphates,...
Although bacterial assemblages are important components of soils in arid ecosystems, the knowledge about composition, life-strategies, and environmental drivers is still fragmentary, especially remote high-elevation mountains. We compared quality quantity heterotrophic between rhizosphere dominant cushion-forming plant Thylacospermum ceaspitosum its surrounding bulk soil two mountain ranges (East Karakoram: 4850-5250 m Little Tibet: 5350-5850 m), communities from cold steppes to subnival...
ABSTRACT Peatland vegetation is composed mostly of mosses, graminoids and ericoid shrubs, these have a distinct impact on peat biogeochemistry. We studied variation in soil microbial communities related to natural peatland microhabitats dominated by Sphagnum, cotton-grass blueberry. hypothesized that such will be occupied structurally functionally different communities, which vary further during the season due changes temperature photosynthetic activity plant dominants. This was addressed...
RIDA®COUNT test plates were used as an easy-to-handle and rapid indicator of microbial counts in karst ecosystems several caves Slovakia Slovenia. All the had a high organic input from water streams, tourists, roosting bat colonies or terrestrial surroundings. We sampled swabs, air samples to robustness universality kit (R-Biopharm AG, Germany, http://www.r-biopharm.com/) for quantification total bacteria, coliforms, yeast mold. Using data swabs (colony-forming units per cm2) we proposed...
Understanding the distribution of taxa and associated traits across different environments is one central questions in microbial ecology. High-throughput sequencing (HTS) studies are presently generating huge volumes data to address this biogeographical topic. However, these often focused on specific environment types or processes leading production individual, unconnected datasets. The large amounts legacy sequence with metadata that exist can be harnessed better place genetic information...
Streptomycetes, typical soil dwellers, can be detected as common colonizers of human bodies, especially the skin, respiratory tract, guts and genital tract using molecular techniques. However, their clinical manifestations isolations are rare. Recently they were discussed possible "coaches" immune system in connection with certain disorders cancer. This work aimed for characterization evaluation genetic adaptations a human-associated strain Streptomyces sp. TR1341. The was isolated from...
As important decomposers of soil organic matter, millipedes contribute to lignocellulose decomposition and nutrient cycling. The degradation requires the action several carbohydrate-active enzymes (CAZymes) and, in most invertebrates, depends on activity mutualistic gut microorganisms. To address question importance microbiota endogenous (host) digestive processes millipedes, we analyzed metatranscriptomic data from tropical millipede Telodeinopus aoutii at holobiont level. Functional...
Methane production by intestinal methanogenic Archaea and their community structure were compared among phylogenetic lineages of millipedes. Tropical temperate millipedes 35 species 17 families investigated. Species that emitted methane mostly in the juliform orders Julida, Spirobolida, Spirostreptida. The irregular distribution correlated with presence methanogen-specific mcrA gene. study brings first detailed survey methanogens' diversity digestive tract Sequences related to...
Abstract Colabomycin E is a new member of the manumycin‐type metabolites produced by strain Streptomyces aureus SOK1/5‐04 and identified genetic screening from library streptomycete strains. The structures colabomycin accompanying congeners were resolved. entire biosynthetic gene cluster was cloned expressed in lividans . Bioinformatic analysis mutagenic studies components pathway that are involved formation both polyketide chains. Recombinant synthases (PKSs) assembled asukamycin routes...
Archaea and bacteria are important drivers for nutrient transformations in soils catalyse the production consumption of greenhouse gases. In this study, we investigate changes archaeal bacterial communities four Czech grassland affected by outdoor cattle husbandry. Two show short-term (3 years; STI) long-term impact (17 LTI), one is regenerating from (REG) a control unaffected (CON). Cattle manure (CMN), source allochthonous microbes, was collected same area. We used pyrosequencing 16S rRNA...
