## Support by Ontologies
[NCBI Taxonomy](https://www.ncbi.nlm.nih.gov/taxonomy) provides an excelent source for organisms.

## Results
Organism details are available in metabolomics repositories. The users usually use the scientific name that can be obtained from [NCBI Taxonomy](https://www.ncbi.nlm.nih.gov/taxonomy). However, some inconsistencies were encountered such as with writing the scientific name (e.g., Mus Musculus instead of Mus musculus), providing a common name (Goat instead of Capra hircus), or providing the source along with the value (e.g., NCBITAXON:Homo sapiens), or even typos.

Some values were ambiguous such as "Various", "Extract", "Multi-species non-defined biofilm consortium" or not even species, such as NMR buffer. Additionally, sometimes, more than one species was mentioned. The combination of species is usually standardized by putting ";" or "/" between the names, but still, the relation between the species is not clear (samples from multiple species vs one sample from a species tissue infected by another species). Lastly, the organism provided varys in rank. Mostly the species is provided, but sometimes it is the genus or strain.

However, even after taking all that was mentioned above, it is still clear that the most studied species are humans (Homo sapiens) and mice (Mus musculus)

## Results

### pH
It was possible to obtain the pH only from MTBLS, even though most of the studies didn't provide this metadata. Most samples' pHs were leaning towards the neutral 7, while a small percentage was around 4.
