Role of the exosporium in the stability of the Bacillus sphaericus binary toxin.
The persistence of toxicity of the Bacillus sphaericus 1593 binary toxin was compared when produced in B. sphaericus, inside the exosporium, or in a recombinant B. thuringiensis strain, outside the exosporium. The stability of the toxin crystal was affected by temperature and quality of the water, but not by the location of the production in the bacterial cell.
