The acquisition of the erythromycin resistance by Bacillus thuringiensis kurstaki improved yields of delta-endotoxins in sporulating cells ranging from 134 to 215%. Resistance to erythromycin decreased the final spore count by at least 50%. Consequently, erythromycin resistance is an efficient tool for the improvement of bioinsecticides yields with a high ratio of delta-endotoxins to spores.
苏云金芽孢杆菌库尔斯塔克亚种对红霉素产生抗性后，芽孢形成细胞中δ-内毒素的产量提高了134%至215%。对红霉素的抗性使最终孢子数至少减少了50%。因此，红霉素抗性是提高生物杀虫剂产量的有效工具，可使δ-内毒素与孢子的比例更高。
