Figure 3From: A time course analysis of the extracellular proteome of Aspergillus nidulans growing on sorghum stoverEstimation of enzyme activities. Levels of xylanase, cellulase, polygalacturonase and mannanase activities in A. nidulans grown on sorghum for 1, 2, 3, 5, 7 and 14 days. Enzyme activities were measured by the released reducing sugars as measured by the 3, 5-dinitrosalicylic acid (DNS) method and expressed as U/ml. One unit of enzyme activity was defined as the amount of enzyme releasing 1 μmol of product per minute. Data represent mean ± SE.Back to article page
