Detection and comparison of rimocidin production (a) and cell dry weight (b) of WT strain S. rimosus M527(●), recombinant strains M527-ER(■), M527-NR(▲), M527-KR(▼), M527-21R(◆) and M527-57R(○) in shake-flask culture experiment. All shake-flask fermentations were carried out in 250 ml flasks with a working volume of 40 ml at 200 rpm and 28 °C. The medium was inoculated at 5% (v/v). The error bars were calculated from three different batches of fermentation
