DescriptionScreening of 402 strains of more than 18 varieties of Bacillus thuringiensis showed chitinase to be inducible in virtually every serovar tested. Though the chitinase titre varied among strains, there was a strong correlation between enhanced lethality to spruce budworm, Choristoneura fumiferana (Clemens), and an increase in chitinase titre within the serovar. Strains grown in chitinase inducing medium gave a more rapid and higher kill than those grown in sporulation medium, and a faster kill than the currently used commercial strain.
