Abstract
PORTELA-DUSSAN, Diana Daniela; CHAPARRO-GIRALDO, Alejandro and LOPEZ-PAZOS, Silvio Alejandro. Bacillus thuringiensis biotechnology in agriculture. Nova [online]. 2013, vol.11, n.20, pp.87-96. ISSN 1794-2470.
Bacillus thuringiensis (Bt) is a Gram-positive rod-shape bacterium that during its sporulation phase produces a parasporal inclusion formed by Cry proteins having biological activity against pest insects. Because of these proteins, Bt shows toxicity toward pest insect larvae of Lepidoptera, Coleoptera and Diptera orders among others, besides of friendly with the environment, and for this reason Bt has a very common use for commercial products and transgenic plants with Cry protein basis in agriculture. In this review is described the most important Bt factors and their application as biotechnological tool in agrobusiness, considering Bt bioassays.
Keywords : Bacillus thuringiensis; Cry protein; pest insect; biopesticide; transgenic crop.
