Abstract: | A net-draft-tube, modified airlift reactor and a stirred-tank reactor were used for thuringiensin production by Bacillus thuringiensis subsp. darmstadiensis growing with various concentrations of molasses. The optimum concentration of molasses for thuringiensin production in both reactors was 15 g/l. There was a 6 h delay in sporulation in the modified airlift reactor compared with that in the stirred-tank reactor. Thuringiensin yield in the modified airlift reactor (2.2 g/l) was consequently higher than that in the stirred-tank reactor (1.1 g/l). |
