Aeration rate effect on the growth kinetics, phytase production and plasmid stability of recombinant Escherichia coli BL21 (DE3)
Phytase production using Escherichia coli BL21 (DE3), a recombinant strain harboring a plasmid encoding thermostable Bacillus phytase, in semi-industrial scale was studied in this work. Among the factors needed to be considered in order to achieve high enzyme yield, aeration rate plays an important role. Suitable aeration is required to supply cells with sufficient amount of air for cell and phyta
