Fig. 6.

Growth curve of Bacillus halotolerans HGR5 under various conditions of stress. a) growth curve under various temperatures, b) growth curve under different pH, c) growth curve under increasing concentrations of NaCl. The error bars show the average standard deviation of each treatment, which was replicated three times.
