A total of 65 samples, consisting of 19 floral materials and 46 soil samples, collected from a coastal area of Lu¨tzow‐Holm Bay on the Antarctic sub‐continent, were examined for the presence of Bacillus thuringiensis . The frequency of samples containing aerobic spore‐forming bacteria was 41·5% and most of the sporeformers were not allied to the B. cereus group. Only one sample from a floating mat of blue‐green algae contained B. cereus ‐like sporeformers. However, there was no evidence for the formation of parasporal inclusions in these isolates. The result suggests that the natural microflora of Antarctica may lack B. thuringiensis , a mesophile widely distributed in other environments.
