Fig. 2. Bacterial tolerance to dehydration at different growing temperatures during in vitro liquid cultures. Two Bacillus species (B. aryabhattai H26-2 and B. siamensis H30-3) and two phytopathogenic bacteria Pectobacterium carotovorum subsp. carotovorum (Pcc) strain PCC21 and Xanthomonas campestris pv. campestris (Xcc) strain 8004 were cultured with increasing concentration (0, 4, 12 and 20%) of polyethylene glycol (PEG) 6000 at different temperatures (30, 40 and 50°C) for 48 h. Bacterial numbers were initially inoculated with 105 cfu/ml and indirectly measured using a spectrophotometer with optical density at 600 nm. Error bars represent the standard errors of the means of the four independent experimental replications. Means followed by the same letter are not significantly different at 5% level by least significant difference test.
