The impact of light intensity on the toxicity of pyrene, a 4-ring polycyclic aromatic hydrocarbon (PAH), was studied in and . Both species were cultured under low light, LL [50-60 μmol(photon) m s], and high light, HL [100-110 μmol(photon) m s] conditions to study the effects of pyrene (PYR) toxicity on growth parameters, the content of biomolecules, chlorophyll content, and photosynthetic efficiency. In the presence of PYR, could grow well in LL and HL intensity. On the other hand, showed a drastic decrease in growth and photosynthesis during HL conditions due to PYR toxicity. Regulation of nonphotochemical and photochemical quenching was responsible for the survival of under PYR toxicity in LL and HL conditions. Thus, seems to be a more promising candidate for pyrene degradation under varying light conditions.
在[具体研究对象1]和[具体研究对象2]中，研究了光照强度对四环多环芳烃芘毒性的影响。两种研究对象均在低光照（LL [50 - 60 μmol(光子) m⁻² s⁻¹]）和高光照（HL [100 - 110 μmol(光子) m⁻² s⁻¹]）条件下培养，以研究芘（PYR）毒性对生长参数、生物分子含量、叶绿素含量和光合效率的影响。在存在芘的情况下，[具体研究对象1]在低光照和高光照强度下均能良好生长。另一方面，由于芘的毒性，[具体研究对象2]在高光照条件下生长和光合作用急剧下降。非光化学猝灭和光化学猝灭的调节作用使得[具体研究对象1]在低光照和高光照条件下芘毒性环境中得以存活。因此，在不同光照条件下，[具体研究对象1]似乎是芘降解更有前景的候选对象。
