Abstract
|
|
|
Growth inhibition and morphological alteration of Bacillus megateriurn NRRL B-1368 in aflatoxin-containing TGY liquid media and its growth restoration in normal media were investigated.
Crude aflatoxins (B₁ 22.7%, B₂ 1.6%, G₁ 3.6% and G₂ 0.2%) at concentrations of more than 20㎍/㎖ inhibited the growth of the microorganism and prevented the formation of septum, resulting in abnormal elongation and disturbance of cell division. The aberrant cells, however, grew normally by septum formation and cell division upon returning to aflatoxin-free culture media. It was, therefore, assumed that aflatoxin affects the function of mesosome related to septum formation in bacteria.
