FFA productivities of Rs-HCA2 and Rs-HXYCA2 grown at high cell densities in the presence of DMSO. a Rs-HCA2 and Rs-HXYCA2 were grown photoheterotrophically in SisH medium with or without DMSO (10 mM) and harvested at the exponential growth phase (OD₆₆₀ of 5.2 and 5.1 for Rs-HCA2 and Rs-HXYCA2, respectively). FFAs in culture supernatants were measured, and the FFA productivity was illustrated with error bars from three independent experiments. b Rs-HCA2 and Rs-HXYCA2 were cultured in SisH medium with or without DMSO (10 mM) under photoheterotrophic conditions; data shown are for one of three representative experiments
