Reply to "comment of 'Hofmeister series: Hydrolytic activity of Aspergillus niger lipase depends on specific anion effects"

Article Abstract:

A Comment which concerns the pH measurements to explain some presumably unclear points by further confirming the occurrence of Hofmeister effects is presented. An attempt is made to show that, independently of the possible effects of ion adsorption at the electrode surface on pH measurements, ion-induced pH variations are not the main cause of the observed ion-specific increases in the enzymatic activity.

Comment on "Hofmeister series: The Hydrolytic activity of Aspergillus niger lipase depends on specific anion effects"

Article Abstract:

A comment on the demonstration of an anionic Hofmeister series affecting the activity of Aspergillus niger lipase is presented. A crude commercial lipase preparation is used to test the effects of different salts on hydrolysis of the chromogenic substrate p-nitrophenyl acetate.

Similarity of salt influences on the pH of buffers, polyelectrolytes, and proteins

Article Abstract:

Changes in pH induced by the addition of electrolytes to buffers, polyelectrolytes and proteins solutions are explored systematically. The pH of triethanolamine and of citrate buffers respectively increases and decreases when salt is added.
