Stability of Biolacta N5 at various substrate concentrations. Residual enzyme activityof Biolacta N5 in (A) buffer, (B) 5.0% (w/w) lactose, (C) 30% (w/w) lactose at ■ 25, 40, xand ▲ 60°C and pH 6.0 with an enzyme concentration of 16 mg∙L-1. The enzyme activity is measured in the o NPG activity assay. (Lines for guidance).
