Microbial community analysis for denitrifying biofilters
… debris. Community fingerprint techniques using ARISA and nosZ t-RFLP were also developed to provide high throughput bacterial and denitrifying community data. The spatial structure of microbial communities in a biofilter was characterized using mapping of ecological metrics, MDS plots, and a new …

A novel flow cytometry based methodology for rapid, highthroughput characterization of microbiome dynamics in anaerobic systems
… automated ribosomal intergenic spacer analysis (ARISA). While ARISA measures diversity at the genomic level and flow cytometry measures diversity at the morphological level, there was an observed correspondence between the two measures at the phylum-level. The present study also suggests that …

Characterization of winter microbial communities in the purple pitcher plant (<i>sarracenia purpurea</i>)
… one population was extracted and amplified using ARISA-PCR, and metabolic substrate usage was measured in 36 pitchers in two populations. Bacteria from eight phyla were recovered. The number of unique genera identified within one leaf ranged from 27-60, and the number of unique phylotypes per …

Microbial community dynamics in denitrifying biofilters receiving agricultural drainage
… Automated Ribosomal Intergenic Spacer Analysis (ARISA), denitrifying bacteria community structure was determined by Terminal Restriction Fragment Length Polymorphism (T-RFLP) of nosZ (one of the nitrous oxide reductase genes), and fungal ARISA (FARISA) was used to determine fungal community …

Molekularbiologische Analyse mikrobieller Gemeinschaften in Talsperrensedimenten
… Mittels Fingerprinttechniken (DGGE, T-RFLP, ARISA) konnten komplexe Muster der mikrobiellen Diversität erzeugt werden. Dabei konnten die Ergebnisse der 16S rDNA Analyse bestätigt werden. Durch die verwendeten Methoden konnte eine komplexe mikrobielle Diversität in den Sedimenten aufgedeckt …

Plant genotype, immunity and soil composition control the rhizosphere microbiome
… in each generation was characterised using ARISA DNA fingerprinting and 454 sequencing. Rhizosphere bacterial and fungal communities are different from those in bulk soil and there are also differences in the microbial community between different plant species. Plants both select and …

Fate and impact of antibiotics in slow-rate biofiltration processes.
… automated ribosomal intergenic spacer analysis (ARISA) revealed shifts in community structure for the high dose CIP experiments. A CFRAB was also used to investigate antibiotic sorption to bacterial biofilm. The extent of sorption, as indicated by the organic carbon partition coefficient (Koc), …

The effects of invasive European Buckthorn (Rhamnus cathartica) on soil microbial community composition
… automated ribosomal intergenic spacer analysis (ARISA) and quantitative PCR (qPCR) to characterize the invaded vs. reference site differences of soil microbial community composition and the abundance of nitrogen-cycling functional groups. I used linear regression to test the hypothesis that …

TurbulenceAlert: Diseño e implementación de un sistema de alerta de turbulencias basado en procesamiento geoespacial y eventos en tiempo real
La turbulencia atmosférica representa uno de los mayores desafíos para la seguridad y eficiencia de la aviación comercial, siendo difícil de predecir con los modelos tradicionales. Este Trabajo de Final de Grado aborda esta problemática mediante el análisis y diseño de "TurbulenceAlert", un sistema …

A Narrative-Focused Machine Learning Approach to Predicting Feature Film Success
<p>For decades, the field of film production has been driven by marketability, and it has relied on gut feelings and subjectivity to produce feature films. The analysis of the relationship between a screenplay’s narrative and a film’s success has been widely overlooked due to the challenges …

Investigation of bacterial community composition and abundance in a lowland arable catchment
… (EFM), automated ribosomal intergenic analysis (ARISA) and 454 pyrosequencing. It also aimed to determine the effects of spatial and temporal variations and environmental factors on bacterial community composition and abundance in this intensively farmed lowland catchment. The three techniques …

Performance, denitrification activity, and microbial community dynamics of denitrifying biofilters under fluctuating water level
… automated ribosomal intergenic spacer analysis (ARISA), and denitrifying bacterial communities were analyzed using terminal restriction fragment length polymorphism (tRFLP) of nosZ, the gene encoding the catalytic subunit of nitrous oxide reduction. In the laboratory biofilter study, the …

Resolving Drivers of Microbial Community Structure in The Dry Valleys of Antarctica
… automated ribosomal intergenic spacer analysis (ARISA). Diversity and community composition were most strongly related to variation in physicochemical soil properties, though significant relationships with topographic and spatial variables were also observed. This identified, for the first time, …

Feedback by the soil microbial community on the distribution of two weeds
… automated ribosomal intergenic spacer analysis (ARISA). I evaluated the relative effects of three forces shaping microbial communities: 1) the source community, which was the initial microbial community present in the local soil of each state; 2) the influence of the training plant species …

The external microbiome of bats: Effects of season, site, host species, and body region
<p>White-nose syndrome is a cutaneous fungal disease that has been detrimental to North American bats for over 10 years, but few investigators have examined the natural microbiota living on these mammals. I explored the influence of season, geographic site, host species, and body region on the …

Bacterial community composition in stream biofilms is influenced by algal response to varying light and phosphorus ratios
Strong correlations between bacterial communities and algal seasonal succession have been previously observed. In aquatic systems, dissolved organic carbon derived by algae is an important resource for bacteria. Light and phosphorus availability are two factors that influence biomass and abundance …
