amylases activity, as it increased the enzymes produced by B.
amyloliquefaciens about 1.26 & 4 and 8-fold, respectively.
Different potato starchy waste concentrations
Five concentrations of potato starchy waste ranging between
0.5% and 2.5% were used for amylases activity by the tested
strain. Data presented in Fig. 6(A) and (B) clearly show that
B. amyloliquefaciens grew exponentially during 36 h in medium
containing potato starchy waste concentrations ranged from
0.5% to 2.5%. The highest figure of growth (0.84 gl1 of cell
dry weight) was recorded at 2% potato starchy waste after
36 h of fermentation periods, which increased about 16.6%,
as compared with that produced at 1% potato starchy waste
