Recombinant strain of Bacillus thuringiensis producing Cyt1A, Cry11B, and the Bacillus sphaericus binary toxin
Applied and Environmental Microbiology 69 (2), 1331-1334
Abstract: A novel recombinant Bacillus thuringiensis subsp. israelensis strain that produces the B. sphaericus binary toxin, Cyt1Aa, and Cry11Ba is described. The toxicity of this strain (50% lethal concentration [LC₅₀] = 1.7 ng/ml) against fourth-instar Culex quinquefasciatus was higher than that of B. thuringiensis subsp. israelensis IPS-82 (LC₅₀ = 7.9 ng/ml) or B. sphaericus 2362 (LC₅₀ = 12.6 ng/ml).
