Abstract excerpt

Various procedures were studied for obtaining Bacillus thuringiensis strains of serotype I which synthesized exotoxins. Mutant clones with elevated exotoxin synthesis could be selected by treating the cells with N-methyl-N-nitro-N-nitrosoguanidine. The frequency of (+) variant selection was from 17 to 12 X 10(-2). The clones of S and R types differed in the insecticide activity of the exotoxin. Its yield could be...
