From: Engineering Escherichia coli for utilization of PET degraded ethylene glycol as sole feedstock
Enhancing E. coli chassis cells for ethylene glycol as a non-sugar feedstock. EG01 underwent continuous cultivation for 24 days, with transfers to fresh medium every two days, covering a span of 12 generations, resulting in the strain EG02. Compared to EG01, after 48 h of cultivation in M9 (10 g/L EG) medium, the final biomass increased from 0.2 ± 0.1 OD to 2.1 ± 0.6 OD, and the uptake rate of ethylene glycol (uptake rate of EG) also rose from 4.8 ± 0.8 mmol/gDW.h to 8.1 ± 1.3 mmol/gDW.h. Error bars indicated standard error (n = 3)
