  1. aThe relative hydrolytic rate was determined as percentage of that obtained with p-NPG for p-NP substrates and percentage of that obtained with cellobiose for di- and polysaccharides
  2. bRelative hydrolytic activity of enzyme on p-NP substrates was calculated by released p-NP concentration
  3. cRelative hydrolytic activity of enzyme on oligo- and polysaccharides was calculated by analyzing the released glucose concentration using DNS method
