Aflatoxin G1was removed from liquid cultures by growing and resting cells of Flavobacterium aurantiacum NRRL B-184. In inoculated culture media containing toxin levels of 7.5 p.p.m. and above, there was a protracted growth lag which was subsequently overcome; toxin removal then occurred, concomitant with growth. Only a few cells demonstrated aberrant morphological forms when cultured in the presence of aflatoxin G1. A comparison of the effects of aflatoxin G1with B1on growth and morphology showed that B1was distinctly more toxic. Three hundred and thirty micrograms of aflatoxin G1was removed per 1 × 1013resting cells during a 4-hour incubation period. Preincubation of resting cells with aflatoxin B1did not interfere with subsequent uptake of G1.
