Analyses of the transcription level of cytochromes and terminal oxidases in correlation with the expression of the photosynthetic apparatus in C. litoralis DSM 17192T. Cultures were grown under the following incubation conditions: (1) with 6 mM malate as sole carbon source and an initial head space gas atmosphere of 6% (v/v) O2, (2) in SYPG complex medium at an initial head space gas atmosphere of 12% (v/v) O2, (3) with 3 mM sucrose at an initial head space gas atmosphere of 12% (v/v) O2. The expression level of the photosynthetic apparatus is given as A880nm/A660nm values. The cytochrome c oxidase activity in whole cells was determined with N,N,N’,N’-tetramethyl-p-phenylenediamine (TMPD) as described previously [15]. The designation of analysed genes is explained in Table 1.
