Neutral sugars are expressed in mol%. Uronic acids and cellulose are expressed in [ µg/mg] fractionated cell wall material. Cellulose was measured after fractionation as release of hexoses from the pellet by Seaman hydrolysis. Significant alterations (n = 3; *: p<0.05, **: p<0.01) are bold and underlined.
