Cry1Ac is a delta endotoxin crystal protein that is produced by gram-positive soil bacterium, Bacillus thuringiensis (Bt) during sporulation, which is dependent on the bacterial strain in numbers and types 5,19, and 43. Bt bacterium spores are toxic if they are ingested by the members of the Lepidoptera order, as the bacterium acts as an insecticide to the larvae.
