For cultivation-independent detection of sulfate-reducing prokaryotes (SRPs) an oligonucleotide microarray consisting 132 16S rRNA gene-targeted probes (18-mers) having hierarchical and parallel (identical) specificity for the all known lineages (SRP-PhyloChip) was designed subsequently evaluated with 41 suitable pure cultures SRPs. The applicability SRP-PhyloChip diversity screening SRPs in environmental clinical samples tested by using from periodontal tooth pockets chemocline a...
ABSTRACT A new microscopic method for simultaneously determining in situ the identities, activities, and specific substrate uptake profiles of individual bacterial cells within complex microbial communities was developed by combining fluorescent hybridization (FISH) performed with rRNA-targeted oligonucleotide probes microautoradiography. This evaluated using defined artificial mixtures Escherichia coli Herpetosiphon aurantiacus under aerobic incubation conditions added [ 3 H]glucose....
BIOMEX (BIOlogy and Mars EXperiment) is an ESA/Roscosmos space exposure experiment housed within the facility EXPOSE-R2 outside Zvezda module on International Space Station (ISS). The design of multiuser supports—among others—the investigations into stability level degradation space-exposed biosignatures such as pigments, secondary metabolites, cell surfaces in contact with a terrestrial analog mineral environment. In parallel, analysis viability investigated organisms has provided relevant...
Interactions between Norway spruce trees and bacteria fungi in nutrient limited boreal forests can be beneficial for tree growth fitness. Tree-level effects of anthropogenic addition have been well studied, however understanding the long-term on associated microbiota is limited. Here, we report sensitivity microbial community composition to growing season additions. High-throughput sequencing bacterial 16S rRNA gene fungal ITS1 region was used characterise changes after application a...
ABSTRACT Hydrogen sulfide-rich groundwater discharges from springs into Lower Kane Cave, Wyoming, where microbial mats dominated by filamentous morphotypes are found. The full-cycle rRNA approach, including 16S gene retrieval and fluorescence in situ hybridization (FISH), was used to identify these filaments. majority of the obtained clones were affiliated with “ Epsilonproteobacteria ” formed two distinct clusters, designated LKC group I II, within this class. Group closely related...
Opioids elicit an increase in the intracellular free Ca2+ concentration ([Ca2+]i) neuroblastoma x glioma hybrid NG108–15 cells, which, depending upon growth conditions, results from either influx differentiated cells or release internal stores undifferentiated (Jin et al., 1992). In this report we describe fura-2-based digital imaging studies that demonstrate opioid- evoked these activation of phospholipase C (PLC) and subsequent mobilization inositol 1,4,5- trisphosphate (IP3)-sensitive...
Summary Lower Kane Cave, Wyoming (USA), has hydrogen sulfide‐bearing springs that discharge into the cave passage. The and stream harbour white filamentous microbial mats dominated by Epsilonproteobacteria . Recently, novel 16S rRNA gene sequences from phylum Acidobacteria , subgroup 7, were found in these mats. Although are ubiquitously distributed many terrestrial marine habitats, little is known about their ecophysiology. To investigate this group Cave more detail, a full‐cycle approach...
Two rover missions to Mars aim detect biomolecules as a sign of extinct or extant life with, among other instruments, Raman spectrometers. However, there are many unknowns about the stability Raman-detectable in martian environment, clouding interpretation results. To quantify biomolecule stability, we exposed seven for 469 days simulated environment outside International Space Station. Ultraviolet radiation (UVR) strongly changed spectra signals, but only minor change was observed when...
The influence of predators on nitrification in aerobic biofilm processes was investigated a laboratory study carried out using two continuous-flow suspended-carrier reactors operating parallel the same synthetic waste water. After established and stable conditions at 3 h hydraulic retention time were achieved, nystatin cycloheximide, substances inhibitory to eucaryotic organisms, added one selectively inhibit predators. other reactor operated as reference, without inhibitors being added....
CO(2) fixation is one of the most important processes on Earth's surface, but our current understanding occurrence and importance chemolithoautotrophy in terrestrial subsurface poor. Groundwater ecosystems, especially at organically polluted sites, have all requirements for autotrophic growth processes, thus suggested to contribute significantly carbon flux these environments. We explored potential microbial communities a petroleum hydrocarbon-contaminated aquifer by detection functional...
The population dynamics of activated sludge in a pilot plant with two systems, both designed for enhanced biological phosphorus removal (EBPR), but one them (BNP) and the other without (BP) nitrogen removal, was monitored during period 2.5 years. influent water to periodically manipulated by external addition (P), acetate glucose, respectively. situ physiology were quantitative fluorescence hybridization (FISH) microautoradiography. Significant P observed systems throughout whole period,...
