Efficient Expression of Maltohexaose-Forming α-Amylase from Bacillus stearothermophilus in Brevibacillus choshinensis SP3 and Its Use in Maltose Production

Figure 3

Dry cell weight (DCW) and extracellular α-amylase activity obtained from the cultivation of recombinant B. choshinensis SP3 using (a) different carbon sources (10 g·L⁻¹); (b) different nitrogen sources (10 g·L⁻¹); (c) different amino acids (5 g·L⁻¹); and (d) different proline concentrations. The DCW and enzyme activity represent the averages of three independent measurements. The error bars represent the standard deviation.
