Phototrophic Growth

Abstract 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.

Reducing Bacteria

Colour changes and other marked disturbances were observed at a high-rate photosynthetic pond system at Alcochete, Portugal. Previous chemical and microbiological tests made it possible to attribute these occurrences to the proliferation of purple sulfur bacteria, following the probable production of sulfide inside the ponds by sulfate-reducing bacteria. Results from more recent tests and observations are presented, which confirm the earlier conclusions, in addition to revealing a number of inadequacies in the ponds chosen operating conditions, which are in all probability at the origin of the observed disturbances. Corrective actions planned include a more efficient mixing of pond contents, the strict prevention of contamination with salty estuarine waters and the control of residence times and bottom sludge accumulation.
