Bt 4A4 (24866589842)

Description:

Summary[edit] Description: Bacillus thuringiensis (Bt) strain 4A4, as viewed at 1000x magnification after gram staining. Bt is a bacterium that is used in a variety of pesticidal applications; 4A4 is acutely toxic to nematodes, which are essentially small worms, and often agricultural pests. Toxin genes from other strains of Bt have been inserted into crops as a means of insecticide, and the bacterium is also used generally as a pesticide.
