GC-MS analysis of P. putida CA-3 mini-Tn5 mutants
P. putida CA-3 | Growth substrate (mM) | PHA (% CDW) |
---|---|---|
Wild type | PA (10) | 23.2 |
E28G12a | PA (10) | 0 |
E22B11a | PA (10) | 0 |
E28G12 and E22B11 are both PhaC1 synthase-negative mutants. Cells were grown on PA for 48 h on E2 medium-8 mM NH4+ before assessment for PHA accumulation.
