Characterization of the inulin hydrolase (CscA) from B. amyloliquefaciens NB. a Optimum temperature; b temperature stability; c optimum pH; and d pH stability. The buffer used for the thermal stability assay was PBS. The buffers used for the pH stability assay were as follows: pH 3–5, Na₂HPO₄–citrate acid buffer; pH 5–8, PBS buffer; and pH 8–10, glycine–NaOH buffer
