In the recent past, the presence of steroid hormones in marine bodies has led to the eruption of endocrine - disrupting molecules which have detrimental effects on aquatic life. However, the resilience and robustness of diatoms to adsorb and grow under the multitude of nutrient stress allow them to utilize the plethora of such compounds. Hence, in this study, we have implemented this unique ability of diatoms to sustain on simulated steroidal wastewater made of estradiol pills and analyze their corresponding impact on growth, biomass production, and lipid synthesis. We hereby report that with an increasing concentration of estradiol (0.5-2.0 mg L) there was an increment in cell numbers, and a 1.5-fold increase in the dry cell weight and lipid content (up to 29.5% DW). Thus, culturing Chaetoceros gracilis in the optimized media had a significant impact on biomass productivity which could further promote the untapped potential of diatoms.
在最近的过去，海洋生物体内类固醇激素的存在导致了内分泌干扰分子的爆发，这些分子对水生生物有不利影响。然而，硅藻在吸收和生长在多种营养压力下的弹性和稳健性允许它们利用大量这样的化合物。因此，在这项研究中，我们利用硅藻在利用模拟甾体废水中的独特能力，这些废水由雌二醇药丸组成，并分析它们对生长、生物量生产和脂质合成的相应影响。我们在此报告，随着雌二醇浓度的增加（0.5-2.0 mg L），细胞数量增加，干细胞重量和脂质含量增加了 1.5 倍（高达 29.5%DW）。因此，在优化的培养基中培养脆杆藻对生物量生产力有显著影响，这可能进一步促进硅藻的未开发潜力。
