Phototrophic growth of Chromatium vinosum strain D on pyruvate or malate, and of Thiocapsa roseopersicina strain 6311 on malate or sulfide as sole electron donors was promotedby 5 mᴍ ʟ-ascorbate, while growth of T. roseopersicina on fructose was inhibited. Slow growth was obtained also with ascorbate alone. In ascorbate-containing cultures the medium developed a yellow to red-brown colour which showed an absorption maximum at 310 -320 nm. As colourless products of ʟ-ascorbic acid degradation by the two strains examined erythroascorbic acid and 2,3-enediol pentonic acid were found in cell-free culture filtrates by gas chromatographic analysis of the silylated residues and identified by their mass, IR and UV spectra. |
