Tween 80, which caused increased biomass formation, also produced the highest increase in the uptake rate of all components of the medium. The fatty acid components of the respective Tweens, i.e. palmitic acid (Tween 40), stearic acid (Tween 60), and oleic acid (Tween 80), have no effect either on alkaloid production or on substrate uptake. The fatty acid composition was different in the cell membrane of the culture supplemented with Tween 60 and facilitated the transport of metabolites into the cells.
吐温80可使生物量增加，同时也使培养基中所有成分的摄取率提高幅度最大。各吐温的脂肪酸成分，即棕榈酸（吐温40）、硬脂酸（吐温60）和油酸（吐温80），对生物碱产生或底物摄取均无影响。添加吐温60的培养物细胞膜中的脂肪酸组成有所不同，这有利于代谢物转运到细胞中。
