1. Production of bio-inseticide Bacillus thuringiensis var. israelensis in semicontinuous processes combined with batch processes for sporulation
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) a
