Systems Approaches to Predict the Functions of Glycoside Hydrolases during the Life Cycle of Aspergillus niger Using Developmental Mutants ∆brlA and ∆flbA
Fig 3
Enzyme activities detected in culture filtrate of batch cultures of strains N402 (squares), ∆flbA (triangles) and ∆brlA (dots).
Protease activity (A), total hydrolytic activity releasing galactose (B) and glucose (C) from the isolated A. niger cell walls and GH exo-activity releasing N-acetyl-glucosamine from GlcNAc-β-pNP (D). Values are given as mean ± SE of measurements performed for two biological duplicates.
