摘要：
Bacillus thuringiensis subsp. medellin was grown until sporulation in a 1.11 fermenter in batch and intermittent fed-batch culture. At optimum conditions 25 g dry cells l(-1) and 9x10(8) spores ml(-1) were produced. Toxicity of the final biomass showed a half lethal concentration on third instar Culex quinquefasciatus larvae of 295 ng ml(-1).
