Conteúdo: | The use of Bacillus thuringiensis for microbial control by itself or as a component in a pest management system has shown its practicability and effective action in a sensible way with pest problems. Although, in Brazil the wider use of Bt depends on the development of new fermentation technology to aim at the production of these endotoxins at reduced costs. One of the most recent studies developed by CNPDA deals with semi-solid fermentation process, using agricultural solid and liquid by-products as components of the fermentation media. Naturally many problems came out during experiments, and some of them has been solved already. The principal problems were the selection of Bt. strain that do not produces exotoxins, the need for monitoring devices and methodsfor this type of fermentation, the chance of contamination that increases when the process in scaled up, and the maintainance of the appropriated humidification. Some of them were not difficult to attain. However, the monitoring devices as well as the control of the heat generated by developing microorganisms, will require considerable innovation by engineers and technicians.
