nutrient medium

This filter is then placed in a nutrient medium.

He floated in a nutrient medium and absorbed what he needed through his spongy exterior.

The smell was intense, of yeast and agar plates and nutrient medium.

Nutritional yeast is produced by culturing a yeast in a nutrient medium for several days.

Cultivation and isolation were completed in a low nutrient medium, DTS.

After irradiation, the cells are moved to a nutrient medium that is known to support cancer cells but not normal cells.

The shape of the cell is affected by the amino acid glycine which is present in the nutrient medium peptone.

Orchid seed is as fine as dust and must be sown on a sterilized nutrient medium in flasks.

Sporangia germinate directly in a nutrient medium by producing germ tubes that develop into mycelial masses.

A viral plaque is a visible structure formed within a cell culture, such as bacterial cultures within some nutrient medium (e.g. agar).

Another method of bacterial culture is liquid culture, in which the desired bacteria are suspended in liquid broth, a nutrient medium.

Testskin is grown in one-inch-diameter molds and is delivered alive to laboratories with a gelatin nutrient medium to keep it alive for five days.

The green scent of crushed grass mixed with the dry tang of mineral dust and the meaty, organic smell of spilled nutrient medium.

In this technique buds, protocorm and meristematic cells are conserved through particular light and temperature arrangements in a nutrient medium.

The synthesis of DNA and nitrogen fixation are initiated 5 hours after the addition of glucose to a nitrogen-free nutrient medium.

One interpretation of all of the correlated adaptations in novel environments is that natural selection favored beneficial mutations that are unaffected by the nutrient medium itself.

The bacteria are selected for their ability to excrete glutamic acid, which is then separated from the nutrient medium and processed into its sodium salt, monosodium glutamate.

Infected human red blood cells are incubated in a culture dish or flask at 37 C together with a nutrient medium and plasma, serum or serum substitutes.

The most common growth media for microorganisms are nutrient broths (liquid nutrient medium) or LB medium (Lysogeny Broth).

The purpose of plate counting is to estimate the number of cells present based on their ability to give rise to colonies under specific conditions of nutrient medium, temperature and time.

At the time it was thought that all infectious agents could be retained by filters and grown on a nutrient medium - this was part of the germ theory of disease.

The hygiene of hard surfaces, such as cooking pots, can be tested by touching them with a solid piece of nutrient medium and then allowing the microorganisms to grow on it.

If either fetal or adult bovine serum is incorporated in the nutrient medium of cell cultures used to propagate PPV, it should be pretested for viral inhibitors.

If contamination is detected before all cells are infected, the virus can be eliminated by repeatedly subculturing the cells in the presence of nutrient medium containing PPV antiserum.

They are using not only recombinant DNA (splicing genes from foreign organisms into the plants' genetic material) but tissue culture, a method of manipulating plant cells in a nutrient medium.
