Measurement of α-amylase activity by use of L. lactis IL 1403 harboring pCUS (A), pMCS-AmyA (B), pCA-AmyA (C), pCA2-AmyA (D), and pCA3-AmyA (E). (a) α-Amylase activity in culture supernatant. (b) α-Amylase activity on the cell surfaces of recombinant L. lactis IL 1403. (c) The ratio of α-amylase activity on the cells to the total α-amylase activity. The data points represent the averages and standard deviations from three independent experiments.
