Recently, scientists came up with the idea of collecting the DNA of organisms
from environmental samples instead, such as soil or water, and determining the various species that way.
Next, the partners want to use their method to measure the concentrations of nanoparticles in a wide variety
of environmental samples.
In the few places where
basic environmental sampling has been done, the results confirm that water and air pollution are present in the same regions where residents say they are getting sick.
Part - time administrative assistant will
receive environmental samples, mail reports and invoices, distribute samples to analysts, provide quality data entry and will review paperwork for all incoming samples.
He also utilizes what he calls «a laboratory in a can» — the newer
Environmental Sample Processor, which collects water samples and conducts on - site analyses.
The interdisciplinary project team is made up of eco - and human toxicologists, physicists, chemists and biologists, and they have just managed to take their first major step forward in achieving their goal: they have developed a method for testing a variety of
environmental samples such as river water, animal tissue, or human urine and blood that can detect nanomaterials at a concentration level of nanogram per liter (ppb — parts per billion).
Viral discovery is performed on human, animals, biologics, and
environmental samples using viral particle enrichment, random nucleic acid amplification, and deep sequencing followed by bioinformatics analysis for the presence of viral sequences.
LABORATORY SKILLS • Proven ability to use laboratory equipment and instruments in a safe and useful manner • Expert in
isolating environmental samples and performing assays • Highly skilled in preparing, analyzing and testing specimens • Working knowledge of preparing comprehensive laboratory and research notes
Using phages for magnetic separation would be «really nice for food and
environmental samples because they tend to be really dirty,» said Michael Wiederoder, a bioengineer at the U.S. Army Natick Soldier Research, Development and Engineering Center in Massachusetts, who was not involved in the research.
That realization coincided with the development of precise laboratory instruments that enabled us to measure chemicals in blood, in urine, and in
environmental samples down to low levels.
Recent developments in the field of metagenomics and single - cell genomics, however, have allowed the reconstruction of archaeal genomes directly from
environmental samples without prior cultivation.
Using a portable, miniature DNA sequencing device (Oxford Nanopore MiniON), the researchers show for the first time that not only can the tool be used for
examining environmental samples in extreme and remote settings, but that it can be combined with other methodology to detect active microbial life in the field.
Additionally, a unique aspect of these AUVs is an
integrated Environmental Sample Processor (ESP), a miniature robotic laboratory that collects and preserves seawater samples at sea, allowing researchers to capture a snapshot of the organisms» genetic material and proteins.

environmental samples during oil ‐ bioremediation — Narjes Dashti — MicrobiologyOpen
Currently, we are exploring
several environmental samples retrieved from allover the world - ranging from hydrothermal vents in Japan to hot springs in Yellowstone National Park and New Zealand — for the presence of novel archaeal (and bacterial) lineages using cultivation - independent approaches, such as metagenomics and single cell genomics.
For researchers working with biofuels, petroleum chemistry, aerosols, and
other environmental samples where large collections of unidentified molecules are the norm, this information is going to be tremendously valuable.
Silver Nanoparticles: No Threat to the Environment - This report will demonstrate that silver nanoparticles do not remain «nanosize» when they come in contact with
normal environmental samples, such as soil and water, but they agglomerate to form much larger, much less biologically effective, silver particles which are non-toxic, non-ionic and have no history of being harmful to the environment or aquatic life.
Depending on the concentration of PCBs,
environmental samples containing PCBs detected at concentrations > 50 mg / kg (or at any concentration if not authorized for use under 40CFR § 761.61) would be subject to the Toxic Substances Control Act (TSCA), and the site would be regulated for both cleanup and disposal under § 761.61.
Collected and
assayed environmental samples from different processing departments, followed by documenting results and notifying key personnel of any significant findings.
Their 38 - page report (including appendices) contains sections on
environmental samples such as soil and swipes from rockets; interviews with more than 50 survivors and with medical staff members; and blood, urine, and hair samples from survivors.
* Conducted routine analytical / microbiological testing of raw materials, packaging materials, finished products and
environmental samples using approved methods, and established policy * Provided technical support and leadership as pertains to analytical / microbiological testing: verify that results are accurate and complete, recogni...
For instance biodiversity research, the study of the variety of life on Earth, is becoming more and more dependent on high - quality tissue and
environmental samples for DNA sequencing.
To date, though, it hasn't been possible to detect very small amounts
in environmental samples,» says Dr. Yvonne Kohl from the Fraunhofer Institute for Biomedical Engineering IBMT in Sulzbach.
3M has introduced an assay and enrichment broth to detect Campylobacter in enriched food and
environmental samples.
3M Food Safety has introduced a new test to monitor lactic acid bacteria in food and
environmental samples.
Specimens obtained from patients tested positive for six strains of legionella, but none of these strains were found to be related to the strains in
the environmental samples.
To achieve this, the scientists are planning to use special filters to remove distracting elements from
the environmental samples, and they are looking forward to develop new processing techniques.
Now the partners in the NanoUmwelt project have developed a method that is capable of identifying even minute amounts of nanomaterials in
environmental samples.
For the detection process to work,
environmental samples have to be appropriately processed.
«Detecting minute nano amounts in
environmental samples.»
«Triclosan's increasing detection in
environmental samples and its increasingly broad use in consumer products may overcome its moderate benefit and present a very real risk of liver toxicity for people, as it does in mice, particularly when combined with other compounds with similar action,» said Robert H. Tukey, PhD, professor in the departments of Chemistry and Biochemistry and Pharmacology.
The authors call for further studies «to evaluate the many additional chemicals used in, and produced by, UOG processes to better quantify the concentrations of these and other contaminants in
environmental samples and to assess the effects of exposure during other sensitive windows of development, including pregnancy and lactation, puberty, and the aging female.»
It involves taking
an environmental sample, sequencing all the DNA in it — its metagenome — then piecing together the genomes of each of the microbes present.
