| dc.description | 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, Co-leoptera 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. | en-US |
| dc.description | Bacillus thuringiensis es un bacilo Gram positivo que durante su fase de esporulación produce una inclusión parasporal, conformada por proteínas Cry con actividad biológica contra insectos-plaga. Gracias a estas proteínas Bacillus thuringiensis presenta toxicidad contra larvas de insectos-plaga de los órdenes Lepidóptera, Coleóptera y Díptera, entre otros. Además es amigable con el medioambiente, razones por la cuales se ha hecho común el uso y desarrollo de productos comerciales y plantas transgénicas a base de toxinas Cry en el sector agrícola. En esta revisión se describirá los aspectos más importantes de Bt y su aplicación como herramienta biotecnológica para el sector agrícola, con una consideración sobre bioensayos usando esta bacteria. | es-ES |
