Sentence examples for cells in environmental samples from inspiring English sources
Recently we showed the applicability and sensitivity of the RNA-based sandwich hybridisation assay (SHA) for detection of Gram-negative cells in environmental samples [Leskelä, T., Tilsala-Timisjärvi, A., Kusnetsov, J., Neubauer, P., Breitenstein, A., 2005.
Through the use of SSU rRNA gene analysis, WGA of single cells, and specific identification of cells in environmental samples using FISH we have confirmed that L. ochracea is phylogenetically related to other species of Leptothrix and Sphaerotilus.
FISH is a useful tool for cultivation independent in situ identification of targeted cells in environmental samples.
These planktonic cells are uncultivated and rarely encountered in environmental samples, obscuring the function and evolutionary origin of the ocelloid.
This allowed us to recover total DNA of the target microbial species, eliminate the different amplification efficiencies among standards and unknown samples, and normalise the rDNA copy number per cell of O. cf. ovata in environmental samples and thus obtain a specific absolute quantification.
The production of organic acids under high sugar concentrations is presumed the result of an overflow mechanism, since cells will not encounter these high concentrations in environmental samples (Maas et al. 2008).
The lack of correspondence observed between microscopic and qrt PCR methods in environmental samples containing low cell numbers, may be explained if we take into account the threshold limits in microscopy counts.
The frequent occurrence of reoviruses in environmental samples could be a potential source of interference with enterovirus detection, especially when enterovirus isolation on cell culture is required.
