Comparison of the results of the standard CellG5 activity assay a with the results of the combination of the CellG5 substrate with softwood b or hardwood pulp c under refining conditions (50% tap water and 50% deionized water at pH 7.0). The obtained degree of refining values (°SR) after refining of softwood or hardwood pulp using 6000 PFI revolutions are indicated above each bar for comparison. Statistical significance was tested using a single factor ANOVA test with a significance level of 0.05 (significantly different results are indicated by the letter s, not significantly different results by the letter n)
