(a) α-PSM fusion cells growth in presence (black) and in absence (grey) of IPTG was analyzed measuring OD600 after 8 h of expression. Error bars indicate ± SE (n = 3). (b) Cell density was determined by calculating the dry weight of the α-PSM fusion cells. Viability of E. coli expressing α-PSMs was evaluated by (c) IP staining and (d) CFU counts. Error bars indicate ± SE (n = 3). Bars labelled as 1, 2, 3 and 4 correspond to cells expressing α-PSM1, α-PSM2, α-PSM3 α-PSM4 fusions to GFP, respectively.
