Sentence examples for concentration of organisms from inspiring English sources

Qualitative samplers sieve organisms from the water without measuring the volume of water passing through, whereas quantitative samplers measure the volume and hence the concentration of organisms in a unit volume of seawater.

The regulation, which largely parallels a pending international standard and another planned by the Environmental Protection Agency, sets an upper limit on the concentration of organisms in the ballast water.

However, since this method only describes the average concentration of organisms that are distributed uniformly throughout the system and cannot express the spatial structure of the system, it was difficult to express ecosystem structures like colonies and density distributions.

The false negative results were obtained for specimens with a lower concentration of organisms.

Infected cells were sonicated and centrifuged at 300×g for 10 min. Supernatants were collected and centrifuged at 10,000×g for 10 min. The concentration of organisms was determined by Gimenez staining, and the bacterial viability was assessed using the LIVE/DEAD BacLight bacterial viability kit (Molecular Probes).

The type of material involved (the bacterial strain, its antimicrobial drug susceptibility, and likely concentration of organisms in the culture) should be noted.
