The concentration of nutrient salts and light were the key factors in limiting cell growth and the synthesis process of the secondary metabolites. With the increase in the renewal rate, the light attenuation was decreased and the concentration of nutrient salts in the semicontinuous culture system increased. Therefore, it is understandable that the effective light and the nutrient supply increased in a suitable range [6, 11], which could explain why a high growth rate was obtained by a suitable renewal rate. However, the concentration of cell biomass and polysaccharide decreased with the further increase of the renewal rates, and as a result, the productivity decreased linearly.
According to the authors’ research data (Tab.1), the total recovery yield correlated with the renewal rate and the concentration of cell biomass and polysaccharide under the specific renewal period, which is similar to that of the renewal period under the specific renewal rate. Moreover, the parabolic ev

浓度的营养盐和轻人的关键因素限制细胞生长和合成过程中次生代谢产物。增加的更新率，光衰减降低和营养盐的浓度的半连续培养系统增加。因此，这是可以理解的有效光线和养分供应增加一个合适的范围内[ 6 ， 11 ] ，这可以解释为什么一个较高的增长速度得到了一个合适的更新率。然而，细胞浓度的生物量和多糖下降，进一步提高利率的延续，因此，生产力下降线性。
根据作者的研究数据（表1 ） ，总回收率相关的更新率和浓度的细胞生物量和多糖根据具体续期时期，这是类似的延长期限的具体更新率。此外，抛演变的总收率反映的是一个充满活力的文化之间的平衡密度和更新制度。因此，最佳的续期制度一样更新率和延长期应是建议恢复产量最高。
同样，一个较高的增长速度可以得到较低延长半期间在文化系统（图3 ） ，但最高生产力的细胞生物量和多糖，只有取得合适的延长期（表2 ） 。最佳营养盐的供应是非常重要的微藻生长的细胞。延长期限延长微藻细胞可以帮助更好地吸收营养，特别是在缺乏氮和磷酸盐。因此，是否缺乏硝态氮和PO4磷造成的，增加了延长期可补偿增加的初始浓度的营养盐仍然需要进行调查。变化浓度硝态氮和PO4磷表明，更新率和延长期确定养分浓度在很大程度上（表1和表2 ） 。以前的作品表明，氮素条件下的缺陷，在某些多糖合成微藻细胞的刺激[ 17 ， 18 ] 。在这项工作中，氮饥饿有人在较低的更新率和较高的重建时期，因此，最高多糖上取得更新率为10 ％ ，并延长任期5 。
