And the conditions in cell suspension culture of Mikania micrantha were studied. The results showed that sucrose was the compatible carbon sucrose, and 30g/L sucrose concentration can satisfy the growth of Mikania micrantha cell; ammonium was absorbed under different sucrose concentration that haven't demonstrated significant specificity, and was completely absorbed on the lag phase and the early logarithmic phase; while nitrate was mainly absorbed on logarithmic phase. The density-dependent of Mikania micrantha cell starting to grow and density-inhibited of cell growth were proposed, the fittest inoculating quantity of Mikania micrantha in cell suspension culture was 40g/L.
并对微甘菊细胞悬浮培养条件进行研究,结果表明,微甘菊细胞生长适宜的碳源是蔗糖,并且较合适的蔗糖浓度为30g/L;在不同蔗糖浓度下氨基氮的吸收差别不大,氨基氮在迟滞期和对数期前期已基本消耗完毕,对数期生长主要利用硝基氮,因而提出,在微甘菊细胞液体悬浮培养中,氮源可以采用初始低氨基氮浓度,对数期中间维持高硝基氮,而且对数期中逐步流加少量的氨基氮;微甘菊细胞迟滞期分裂启动存在密度依赖现象,对数期生长存在密度抑制现象,最适接种量为40g/L。
