Abstract
Several novel strains of “Sulfolobus islandicus” produced proteinaceous toxins, termed sulfolobicins, which killed cells of other strains of the same species, as well as of Sulfolobus solfataricus P1 and Sulfolobus shibatae B12, but not of the producer strains and of Sulfolobus acidocaldariusDSM639. The sulfolobicin purified from the strain HEN2/2 had a molecular mass of about 20 kDa. It was found to be associated with the producer cells as well as with cell-derived S-layer-coated spherical membrane vesicles 90 to 180 nm in diameter and was not released from the cells in soluble form.Keywords
