Bacillus thuringiensis: Producer of Potent Insecticidal Toxins

1998
Ishwata initially described Bacillus thuringiensis at the turn of the 19th century as the causal agent of the “sotto bacillus disease ” of the silkworm Bombyx mori. Later studies by Aoki in 1915 demonstrated that this bacterial agent produced a crystalline toxic material at sporulation. In 1911, Berliner isolated the type species Bacillus thuringiensis

Effect of heat-stable Bacillus thuringiensis toxin on armyworms

Journal of Invertebrate Pathology, 1967
Abstract Heat-stable exotoxin from 48-hour cultures of Bacillus thuringiensis was injected into sixth-instar larvae of Pseudaletia unipuncta . The toxin either killed the larvae before completing pupation, or it caused a delay in pupation and the occurrence of unevenly melanized and malformed pupae.

Toxin and virulence gene expression in Bacillus thuringiensis

2000
At the end of vegetative growth and in response to various nutrient stresses, Bacillus species produce specific components (degradative enzymes, antibiotics, toxins) allowing the bacteria to rapidly adapt to the environment, to eliminate competitors and to gain access to novel sources of nutrients.
