Summary: A significant yield of aflatoxin B 1 was produced by the chlamydospore growth phase of Aspergillus parasiticus grown on a synthetic liquid medium. Morphology and structure of the fungus growth is fully described. The two stage addition of 2‐C 14 ‐acetate to the medium proved to improve dramatically the efficiency of labeling the toxic metabolite. Zusammenfassung: Eine signifikante Ausbeute an Aflatoxin B 1 konnte aus der Chlamydosporen‐Wuchsphase von Aspergillus parasiticus auf einem synthetischen flüssigen Medium gewonnen werden. Die Morphologie des Pilzwachstums wird ausführlich beschrieben. Die Zugabe von Natriumacetat‐2‐C 14 zu dem Medium in zwei Stufen ergab eine dramatische Steigerung der Ausbeute an markierten Toxin.
