- SB: Sodium Butyrate, SH: Sodium hexanoate
- SB:SH (2:1): 3 gL-1 SB was added at 0 h and 12 h during the cultivation process to form the PHB block After 24 h 3 g L-1 SH was added to form the PHHx block
- SB:SH (1:2) : 3 gL-1 SB was added at 0 h and 3 g L-1 SH was fed at 12 h and 24 h of the cell growth.
- Each shake flask process continued for 48 h. 20 g/l of glucose was fed at 0 h as a nutrient in each case of block formation. PHA samples were analyzed by GC [27]
- All cells were grown in LB media for 48 h at 30 °C in the rotary shaker (HNY-2112B, Tianjin Honour Instrument Co. Ltd. China).
