Thaxtomin A (1) and B (2), the two major phytotoxins associated with the common scab of potato disease, were transformed into C-14 linked β-glucosides (3) and (4), respectively, when individually incubated with cultures of Bacillus mycoides in oatmeal broth at 26 °C. These biotransformation products when assayed on aseptically produced potato minitubers proved to be much less phytotoxic than the parent compounds.
