Resumo:  The aim of this work was to study the production of the bioinsecticide using the aerobic cultivation. Two-stage cultivation process was used: aerobic vegetative growth and end-phase of sporulation (with aeration and without aeration). The cuts of working volume evaluated were 20, 40, 60 and 80 %. The highest value of spore concentration (2.17x10(9) CFU/mL) and spore productivity (7.2x10(7) CFU/mL.h) were observed using SP60. The lethal concentration (CL50) obtained through the aeration process and non-aeration process were 0.21 and 0.05 mg/L, respectively. The specific potential of the bioinsecticide produced without aeration (0.025 mg/10-12 CFU) was two times higher than that obtained with aeration (0.05 mg/10-12 CFU).
