A proteinaceous toxin has been extralctcd from sporulated cultures of Bacillus sollo Ishiwata. The toxin is similar in amino acid composition and biological activity, to the crystalline inclusions produced by this microorganism and it appears that the toxic protein is associated with the crystals. The toxin is stable, and causes paralysis and death in the larvae of Bombyx mori L. (the silkworm) and other lepidopterous insects. Thc symptoms caused by the toxin are identical with those caused by ingestion of the whole microorganism.
