Note that pH is unit-less and there is a space before the degree symbol. The hydrophobic-amino acids are non-polar, and limit their exposure to water. These residues tend to bury themselves towards the cores of proteins. foa meeting
Biodegradation of selected hydrocarbons by novel bacterial
WebThe pH of the water is important relative to the varying proportions of the hypochlorous acid and hypochlorite ions. In a solution with pH rising over 6.0 the proportion of hypochlorous acid declines from virtually 100% down to almost 0 at pH 9.0. The activity of hypochlorous acid as a bactericide is greatly superior to that of the Web2.2.2.6 Petroleum hydrocarbons.
