Electron microscopy studies on cell morphology and PHA production of E. coli JM109 ∆minCD overexpressing ftsZ. SEM morphology studies on: a E. coli JM109 (p15a-blank). b E. coli JM109 ∆minCD (p15a-blank). c E. coli JM109 ∆minCD (p15a-ftsZ). Cells were cultivated in LB medium. Scale bars, 10 μm. d The cell dry weight and PHA accumulation by E. coli JM109 ∆minCD overexpressing ftsZ with pBHR68. Cells were cultivated in LB medium at 37 °C for 48 h, 0.2 % arabinose was added into the medium after 2 h of inoculation, and 20 g/L glucose was added 6 h later. Error bars are s.d. (n = 3)
