ASSOCIATION OF TOXICITY WITH PROTEIN-CRYSTALLINE INCLUSIONS OF BACILLUS SOTTO ISHIWATA

Abstract

The toxic principle in sporulated cultures of Bacillus sotto, which causes paralysis and death in Bombyx mori larvae, is associated with the crystalline inclusions produced by this microorganism. The toxin is not present as a typical exotoxin but is soluble either in silkworm gut juice or dilute alkali solutions.
