Description:
Enrichment cultures were prepared with different media for phototrophic bacteria from four species of marine sponges, collected from oxic coastal waters near Split (Yugoslavia). We obtained pure cultures of six strains of Chromatiaceae and two strains of Rhodospirillaceae by agar shake dilution. The Rhodospirillaceae were identified as Rhodopseudomonas sulfidophila and a marine form of Rhodopseudomonas palustris. TheChromatiaceae were identified as Chromatium vinosum, Chromatium gracile, Chromatium minutissimum. Ectothiorhodospira mobilis, and a Chromatium species, which in some respects resembles Chromatium minus. The occurrence of strictly anaerobic phototrophic bacteria in aerobic sponges is discussed with respect to nutrition and possible syntrophism
