Growth of P. haloplanktis strain TAC125 in a shake flask on modified DSMZ 79 medium supplemented with 5 g l-1 soy peptone (SP). The cultivation was performed in a 3 l Erlenmeyer flask on a rotary shaker at 160 rpm at 16°C. DOT and pH were measured online with the SENBIT®-system. Spikes in the DOT curves derive from stops of the shaker during sampling. Composition and concentrations of the single amino acids of the soy peptone-containing medium (pepton N-Z-soy BL4/BL7) were analysed via GC-MS. (A) DOT, pH, growth curve and corresponding specific growth rate; (B-E) amino acids.
