Antibiotika als pflanzliche Plasmagifte

Summary

The toxic action oflycomarasmine (a wilting agent produced byFusarium lycopersici Sacc., the causal organism of tomato-wilting) and ofpatulin (clavacin, an antibiotic produced byPenicillium patulum and by some other fungi) on some test-objects is studied (anthocyanin-test with red turnips, plasma-streaming test withSpirogyra etc.). Both substances are able to destroy for instance the semipermeability of the plasma boundary layer; but patulin proves to be more toxic for these objects than lycomarasmine, the specific poison of the tomato wilting disease.
