The phrase
"microbial cells" refers to very tiny living organisms that cannot be seen with the naked eye. They are made up of a single cell and include bacteria, viruses, and fungi.
Full definition
In recent years, research has shown that what people commonly think of as «their» bodies contain roughly 10
microbial cells for each genetically human one.

percent microbial cells.

microbial cells as human cells within their bodies; countless more populate the environment around us.

many microbial cells as human cells in and on any of us, and none of that DNA seems to get mixed up with Goldblum.

microbial cells per cubic centimeter of sediment.
«We can
engineer microbial cells to produce many different chemicals from simple sugars, but the cells would rather use those sugars to grow and reproduce.
Single cell genomics is an emerging technology enabling the exploration of genomes of
individual microbial cells without the need for prior cultivation.
Aeolian deposition is responsible for sorting and transporting lithogenic matter (primarily sand - and clay - sized particles), containing
microbial cells from the surrounding desert environments (soils, ephemeral streams, glaciers, etc.) onto the ice covers that range in thickness from 3 to 20 meters.
Damaged or worn plastic becomes difficult to clean and can easily fill with organic matter that
microbial cells feed on to survive and grow.
High in the Cederberg Mountains of South Africa grows a bristly shrub that embodies the tug - of - war taking place between industrialized and developing nations over the value of genetic resources — the genes found in plant, animal or
microbial cells used for research as well as in commercial products, such as enhanced seeds and naturally derived cosmetics and pharmaceuticals.
As a result, oxygen saturation at depth dropped from an average of 67 percent to 59 percent
while microbial cell concentrations doubled to 5,510 cells per milliliter compared with just 2,730 cells per milliliter outside the plume.
There are about as many
microbial cells in our body as our own cells, and they appear to be transmitted from mother to child during birth and continually altered by the home environment, type of diet, medications and even the family pet.
«We measured the metabolic activity levels of
microbial cells isolated from different areas of our skin and found that about 90 % of the bacteria on our skin are either dead or inactive» said Cummins.
The MIT team hypothesized that natural shape - shifters such as yeast, bacteria, and
other microbial cells might be used as building blocks to construct moisture - responsive fabrics.
Powered by the synthetic genome, that
microbial cell began replicating and making a new set of proteins.
Scientists are only beginning to understand what role the billions of
microbial cells colonizing the human gut play in diet and disease.
Viral infections simultaneously reduce the amount of nutrients and materials available to larger organisms by
killing microbial cells, but also stimulate microbial activity through the release of organic matter and nutrients, which provides increased biomass available for larger organisms including fish.»
«As they
destroy microbial cells, they change the forms of nutrients available to other, larger organisms in ocean ecosystems.
The SAM team has already sniffed organic molecules in surprising abundances, and they have found tantalizing hints of degraded fatty acids — in theory, a possible trace of
ancient microbial cell walls.
As
microbial cells die, they free up their phosphorus, giving plant roots an opportunity to take it up.»
After screening more than 100,000 compounds, the researchers found several potent LexA inhibitors that all but halt the ability of bacteria to mutate and also easily get
inside microbial cells, a notoriously difficult challenge for would - be drugs.
It's a model known as «kill - the - winner» — the winners being the
blooming microbial cells and the killers being the viruses (mostly bacteria - killing viruses known as bacteriophages) that infect them.
Examples include imaging techniques ranging from confocal advances to cryotomography — which can resolve subcellular structure and
reveal microbial cell function — and ways to monitor the production and exchange of microbial metabolites.
The modern age of biologics began 35 years ago with the approval of Lilly's Humulin product — a biosynthetic form of human insulin derived from recombinant DNA and
microbial cell culture (1).
Michael Sieracki and Jane Heywood at an inFlux fluorescence - activated cell sorter, a device used to separate out individual
microbial cells at Bigelow Laboratory Single Cell Genomics Center.
The human body is typically home to some hundred trillion
microbial cells comprised of five million different genes, adding up to nearly 5 pounds of micro-organisms per person.
They found that Lake Whillans was thriving, with roughly 130,000
microbial cells per milliliter of water.
These new microbes — led by one particular unusually long (20 microns), yet to be named species that made up more roughly 95 percent of the community responding to the spill — had consumed roughly 8 percent of the available oxygen in these cold, deep waters as they busily converted hydrocarbons into
more microbial cells, limited only by a lack of iron.
«But what I find most interesting in Parkes» samples is the high density
of microbial cells.
Corrugated surfaces were able to entrap
the microbial cells within their fibers.
These complex sugars are indigestible by the infant but appear to play a powerful role in shaping an infant's gut microbiome, the fine - tuned community of trillions of
microbial cells that, again, scientists are only beginning to understand.
The human gut consists of up to 100 trillion
microbial cells that influence metabolism, nutrition and immune function.
The result was an extremely high - throughput sequencing protocol that, in a single run, can cover portions of the genomes of over 50,000
microbial cells (2).
These microbial cells outnumber our own by 10 to 1, with most of them colonising the gut.
The microbial cells they have used are also proven to be safe to touch and even consume.
In nature, biologists have observed that living things and their components, from pine cone scales to
microbial cells and even specific proteins, can change their structures or volumes when there is a change in humidity.
