A study was carried out to evaluate the growth performance of , a green microalga, in three different concentrations of digested rotten potato supernatant (DRPS) for 16 days. was grown in 20 % (T), 40 % (T), and 60 % (T) of the DRPS and at the same time in Bold Basal Medium (BBM) as a control (T). A significantly highest cell density of was found in T (192.83 ± 1.75 × 10 cells mL) in comparison to T (136.83 ± 5.58 × 10 cells mL), and T (99.11 ± 5.38 × 10 cells mL) (p < 0.001 for all comparisons) while the cell density at T (192.83 ± 1.75 × 10 cells mL) and T (180.907 ± 4.58 × 10 cells mL) did not differ significantly (p = 0.227). Moreover, the mean daily division rate of was significantly higher in T (0.340 ± 0.001 divisions day) in comparison to other concentrations of DRPS (p < 0.001 for all comparisons). The maximum value of total biomass (1.07 ± 0.10 g L) was found in T which was statistically similar to those in T and T. In addition, there was no significant difference between the mean maximum values of chlorophyll- content and optical density of in T and T. The highest protein content of 42.67 ± 0.57 % was observed in T which was significantly higher than T (39.43 ± 1.67 %) (p = 0.027). It is also worth mentioning that there was no significant difference in the crude lipid content of the microalgae grown in T (10.06 ± 0.17 %) and T (9.88 ± 0.14 %) (p = 0.616). Hence, 20 % DRPS can be used as an alternative culture media of BBM for with a broad aim to accelerate the sustainable advancement of microalgal production.
开展了一项研究，以评估一种绿色微藻在三种不同浓度的消化腐烂马铃薯上清液（DRPS）中16天的生长性能。该微藻在20%（T1）、40%（T2）和60%（T3）的DRPS中培养，同时在Bold基础培养基（BBM）中作为对照（T0）培养。与T2（136.83±5.58×10⁶个细胞/mL）和T3（99.11±5.38×10⁶个细胞/mL）相比，在T1（192.83±1.75×10⁶个细胞/mL）中发现该微藻的细胞密度显著最高（所有比较p<0.001），而T1（192.83±1.75×10⁶个细胞/mL）和T0（180.907±4.58×10⁶个细胞/mL）的细胞密度没有显著差异（p=0.227）。此外，与其他浓度的DRPS相比，T1中该微藻的平均日分裂率显著更高（所有比较p<0.001）。在T1中发现总生物量的最大值为（1.07±0.10 g/L），在统计学上与T2和T0中的值相似。此外，T1和T0中该微藻叶绿素含量的平均最大值和光密度之间没有显著差异。在T1中观察到最高蛋白质含量为42.67±0.57%，显著高于T2（39.43±1.67%）（p=0.027）。还值得一提的是，在T1（10.06±0.17%）和T2（9.88±0.14%）中培养的微藻粗脂肪含量没有显著差异（p=0.616）。因此，20%的DRPS可作为BBM的替代培养基用于该微藻，以广泛加速微藻生产的可持续发展。
