Figure 7From: Cloning, expression in Pichia pastoris, and characterization of a thermostable GH5 mannan endo-1,4-β-mannosidase from Aspergillus niger BK01Effect of pH on stability of A. niger BK01 β-mannanase. The pH stability was reported as relative residual activity after the enzyme was incubated in 0.1 M citrate-phosphate buffer at various pHs without substrate for different periods of time at 50°C.Back to article page
