The cell density increased with an increase of the renewal period and reached the maximum value with the renewal period of 4d (1375.2±24.7×104 cell/mL ) at the 22th day, although the maximum average growth rate K was obtained at the renewal period of 10%。
The addition of the renewal period resulted in a higher recovery yield process for cell biomass and polysaccharides, following a parabola evolution as shown in table 2. The yield of the cell biomass with the renewal period of 4 d was 1.6 times as much as that with the renewal period of 1 d, which had distinct differences (p<0.01) between their mean values. Similarly, the high total recovery yield of polysaccharide was obtained under the renewal period of 4 d with statistical differences being found among them (p<0.05). The parabolic equation is shown in figures (7) and (8).

根据上述数据,以减少续期期间,硝态氮和PO4 - P的文化液体不能及时消耗的紫球藻细胞,因此,更多的硝态氮和PO4 - P的积累了细胞密度的增加而增加了延长期和达到最大的价值与重建时期的四维( 1375.2 ± 24.7 × 104个细胞/毫升)在22日一天,虽然最高平均增长率钾索取延长期的10 % 。

此外续期期间导致了较高的回收率进程的细胞生物量和多糖,下列抛物线演变如表2所示。产量的细胞生物量与重建时期的4个D为1.6倍,在延长期的1个D ,这独特的差异( P “ 0.01 )之间的平均值。同样,总回收率高多糖下获得延长期限4个D与统计差异发现其中( p “ 0.05 ) 。抛物型方程的数字显示( 7 )及( 8 ) 。

细胞密度增加了与更新期间的增量并且到达了与4d (1375.2±24.7×104 cell/mL)的更新期间的最大价值在22th天,虽然最大平均增长率K获得了在10%。的更新期间 更新期间的The加法导致细胞生物量和多聚糖的一个更高的补救出产量过程,跟随抛物线演变如表2.所显示。 细胞生物量的出产量与更新期间的4 d是1.6倍象那与1 d的更新期间,有明显区别(p
