Fig. 4From: Improvement of macrolactins production by the genetic adaptation of Bacillus siamensis A72 to saline stress via adaptive laboratory evolutionONPG test results. β-Galactosidase activity was monitored by an increased absorbance at 420 nm. Membrane permeability of A72 is shown as green hollow triangles and that of IMD4001 is shown as orange hollow diamonds. Values and error bars represent the mean and standard deviation value (n = 3 cultivations)Back to article page
