Bacillus thuringiensis: the legacy to the XXI century

Bacillus thuringiensis: the legacy to the XXI century

Bacillus thuringiensis-based insecticides are the main production line of the biopesticides world market. The research devoted to this area, promoted by the necessity to solve problems in agriculture and public health has resulted in an exhaustive knowledge of its biology. The diversity of the B. thuringiensis strains has permitted to develop several products mainly, but not exclusively, for insect control. With the new developments in the field of molecular biology, it has been possible to understand the molecular basis of the mode of action and to increase the range of activity as well. As a result of the broad use in several countries, resistant strains of some of the susceptible insects have appeared. The aim of this review is to elaborate a theoretical framework of the current state of research on B. thuringiensis, describing briefly the knowledge on this bacterium, with emphasis on biological phenomena that underlie its toxic activity and the problems that will be faced during the XXI century with the increasingly common resistance, all this analyzed from a biotechnological perspective.

Los insecticidas basados en la bacteria Bacillus thuringiensis son el principal renglón productivo del mercado mundial de biopesticidas. La investigación dedicada a esta área, promovida por la urgente necesidad de resolver problemas agrícolas y de salud pública, ha dado lugar a un conocimiento exhaustivo de su biología. La diversidad de cepas diferentes de B. thuringiensis ha permitido desarrollar productos principalmente, pero no exclusivamente, para el control de insectos. Con los nuevos desarrollos de la biología molecular, se ha logrado comprender su mecanismo de acción a nivel molecular y también se ha logrado extender sus capacidades entomopatógenas. Como producto de su amplio uso en muchos países, se han presentado casos de resistencia en poblaciones de insectos susceptibles. Con esta revisión se pretende elaborar un contexto teórico del estado actual de la investigación sobre B. thuringiensis, describiendo brevemente el conocimiento sobre esta bacteria, haciendo hincapié en los fenómenos biológicos que subyacen su actividad tóxica y la problemática que se avecina en el próximo siglo con los fenómenos de resistencia cada vez más comunes, todo esto analizado desde una perspectiva biotecnológica.
