Table 1 Effect of the initial phosphate concentration in T. thermophilus growth, rhamnolipids production and PHAs production and compositiona
From: Simultaneous polyhydroxyalkanoates and rhamnolipids production by Thermus thermophilus HB8
Phosphate concentration (mM) | Biomass (CDWb) (mg/L) | Rhamnolipids (mg/L) | Yield of Rhamnolipids (% DCW) | PHA (mg/L) | PHA content (% DCW) | monomer composition (%mole) | |||
