Although B. thuringiensis is most known for the plethora of Cry and Cyt proteins it produces, strains of this microbe produces other proteins that have applied biotechnological value, including chitinases, vegetative insecticidal proteins (Vip) and enhancing-like proteins, antimicrobial peptides and parasporins which can be used to synergize the activity of Cry proteins, to control lepidopteran and coleopteran pests, to inhibit food-borne pathogenic bacteria and to kill human cancer cells of various origins, respectively1,14,16. This evidence concerns the gene CRYL1 and cancer.
