Effects of sodium chloride and high pH stress on growth and ethanol-consuming activities of Pannonibacter phragmitetus. a Growth (left) and ethanol consumption (right) of Pannonibacter phragmitetus in BG11 medium with 0 mM NaCl (shown in black column), 300 mM NaCl (shown in red column) and 600 mM NaCl (shown in blue column). b Growths of Pannonibacter phragmitetus in BG11 medium with original pH (open circle) and pH 10 (open triangle). c Ethanol consuming activities of Pannonibacter phragmitetus in BG11 medium with original pH (open circle) and pH 10 (open triangle), the natural evaporation (open square) was taken as a control. Error bars corresponded to the standard deviation determined from three independent experiments. d Growths of Pannonibacter phragmitetus cells cultivated in BG11 medium with original pH, pH 10 and pH 11.0 for 3 days
