Growth of the microorganisms on standard tissue propagation and general fungal/oomycete media differed for each of the 13 isolates tested (Table 2, data only shown for six of the isolates tested).
Part of the CSF sample from all animals was used for confirmation of the presence of microorganisms using standard microbiological tests (10 15 µl CSF).
This deficiency results from the inability to culture most microorganisms using standard microbiological techniques.
As the exploitation of microbial diversity is impaired by the ability to cultivate soil microorganisms under standard laboratory conditions, a metagenomic approach, consisting of total DNA extraction from a given environment followed by cloning of DNA into suitable vectors, was undertaken.
This avoids bias that results from the non-culturability of a large proportion of microorganisms in standard culture conditions (Rappe and Giovannoni 2003) and from variation in the effects of environmental media on the success of culture-based techniques (Allen et al. 2010).
When deployed against samples from the treatment system, they showed superior operational range and sensing capabilities to that observed for industry standard microorganisms such as Vibrio fischeri.
The chemostat is a very important resource-based model for the continuous culture of competition microorganisms and a standard model for the laboratory apparatus on bioreactor, which have been studied from various views such as population dynamics and species interactions [1 17].
For selected microorganisms we used standard agar diffusion procedures (Kirby and Bauer) or E-Test (bioMérieux, France) to establish antibiograms [ 6, 7].
Patient clinical parameters were also recorded including the participant's age, lung function, pulmonary administered steroids or antibiotics, and colonization by microorganisms identified by standard clinical laboratory cultivation techniques.
In one respect, the availability of a well sequenced and annotated genome may constitute a major limitation: while accurate metabolic reconstructions are available for un-mutated, standard microorganisms such as E. coli and S. cerevisiae, in an industrial setting a larger diversity of organisms are used, particularly animal cell systems for which cellular data is much scarcer [ 41].
When a bottle turned positive, 100 μL of the fluid was cultured and incubated followed by microorganism identification using standard procedures.
