Measurement of the Galactanase Activity of the GanB Galactanase Protein from Bacillus subtilis
Author:  Hildegard Watzlawick, date: 04/05/2017, view: 3086, Q&A: 0
The activity of the endo-β-1,4-galactanase GanB from B. subtilis on the high molecular weight β-1,4-galactan was determined quantitatively by the measurement of the increase of the reducing power or with the dyed substrate Azo-galactan. The ...
