The production rate increased significantly as values for YP/X rose from 0.19 g/g (batch, medium B) to 0.26 g/g (fed-batch, medium C).
The maximal Surfactin concentration in foam did not increase during cultivation employing medium C (3.67 g/L Surfactin in comparison to 3.99 g/L Surfactin applying medium B), but the total foam volume leaving the bioreactor increased from 334 mL (batch, medium B) to 435 mL (fed-batch, medium C).
Post sterile additions for a batch medium were prepared as concentrated stocks, filter sterilized, and injected into the bioreactor through a septum on the head plate.
A single colony was picked from the plate and inoculated into the 5 ml batch medium (LBT or 7H9) in a 30 ml glass universal and incubated at 37°C on a rotary shaker at 200 rpm.
The fermenter software (BioXpert) was programmed to calculate feed rates according to the following equation:
Ammonium sulfate in the batch medium was utilized in the first 40 hours and the amount of ammonium hydroxide added to correct the pH thereafter did not result in ammonia accumulation until 95 hours (Figure 3b) while supporting maximum cell density of 235 OD600 (Figure 3a).

When glucose was reduced to 9.0 g/L at 37 h, the fed-batch medium containing ~400 g/L glucose was fed into the bioreactor intermittently until the end of fermentation.
When peptone was included in the fed-batch medium (together with lactose and glycerol), E. coli strain BL21 mHO1) bioreactor cultures produced between18.4 to 25.3mg L-1 (n=11, average of 23.8 mg L-1) of biliverdin.
The optimal flask-shaking batch fermentation medium for phenazine-1-carboxylic acid (PCA) production by Pseudomonas sp. M-18Q, a qscR chromosomal inactivated mutant of the strain M18 was studied using statistical experimental design and analysis.
Increasing the concentration of sodium nitrate in batch culture medium was expected to increase the production of both CDM and PHB; however, the production of CDM and PHB decreased compared with the levels observed in previous studies (Fig. 1a, b) (Kawata et al. 2013, 2014).
