Fig 4. Comparison of the production of neutral protease in shake flasks and fermentors.

Fig 4

a The enzyme activity of r-BaNPR and BaNPR produced by Bacillus amyloliquefaciens 110N-6 and Bacillus amyloliquefaciens K11 on flask level under optimized conditions. b The enzyme activity of r-BaNPR and BsNPR produced by B. amyloliquefaciens 110N-6 and Bacillus subtilis 1398 on large-scale batch production in the fermentor. Each value in the panel represents the means ± SD (n = 3).
