Whereas the concentration of hydrogen ions equals the concentration of the acid for strong acids such as hydrochloric acid (HCl) due to its complete ionization in solution, which means that such concentration is 0.00125 M. Thus, the pH turns out:
This particular organism lives in an environment that is rich in organic material, particularly amino acids and proteins. Also the organism has low amount of amino acid biosynthesizing genes and relatively higher amount of peptide transporters.
