2.1. Strains and normal growth conditions
Wild type Synechocystis sp. PCC 6803 was grown in BG11 medium
containing 17.6 mM NaNO3 as a source of nitrogen and buffered
with 20 mM HEPES-NaOH (pH = 7.5) as described
previously (Baebprasert et al., 2010). All overexpressing (OE)
strains (phaAB, phaEC and phaABEC) were grown in BG11 medium
containing 30 lg/mL chloramphenicol.
