Barjac, H. de; Burgerjon, A., 1973: Studies on the presence of the thermostable toxin in serotypes 10, 11 and 12 of Bacillus thuringiensis. Journal of Invertebrate Pathology 21(3): 325-327
In further studies on the production by Bacillus thuringiensis of the thermostable exotoxin, bioassay with third-instar larvae of Pieris brassicae L. of supernatants of autoclaved cultures of the varieties darmstadiensis (serotype 10 , toumanoffi (serotype 11 and thompsoni (serotype 12 , indicated that the toxin is produced by serotype 10 in about the same quantities as by serotype 1 but not at all or in only very limited amounts by serotypes 11 and 12.
