Differences in wild type and engineered E. coli on PLH production in 5 L fermenter.

Chemical	Strains characteristics	PLH contents (wt%)	Titer (g L−1)	Productivity (g L−1 h−1)	DCW (g L−1)
PLH	E. coli DQ0 (PLH pathway)	26.77	6.02	0.07	22.48
	E. coli DQ280 (PLH pathway + C and D period)	43.86 (p = 0.011)	10.61 (p = 0.012)	0.13 (p = 0.012)	24.19 (p = 0.204)
	E. coli DQ8 in the dark condition (PLH pathway + BARNA-controlled C and D period, dark)	28.79 (p = 0.220)	6.68 (p = 0.259)	0.08 (p = 0.259)	23.21 (p = 0.781)
	E. coli DQ8 in the light condition (PLH pathway + BARNA-controlled C and D period, light)	53.8 (p = 0.003)	14.31 (p = 0.001)	0.17 (p = 0.001)	26.6 (p = 0.007)

Significance (p-value) was relative to the control strain E. coli DQ0; Differences were determined by two-tailed Student’s t-test.
