摘要

草甘膦是一种有毒的环境污染物,具有诱导生物体内生化和生理变化的能力。一些研究集中在对这种污染物引起的应激的保护技术的研究上。在此背景下,我们研究了螺旋藻对草甘膦干扰的保护作用。采用生物标志物方法测定草甘膦、螺旋藻及其混合物在两个时间段(4天和7天)对褐贻贝的影响。草甘膦处理贻贝的丙二醛水平显著升高,乙酰胆碱酯酶(AChE)水平显著降低。螺旋藻过氧化氢酶(CAT)、谷胱甘肽- s -转移酶(GST)和乙酰胆碱酯酶(AChE)活性正常化。此外,它还降低了草甘膦诱导的丙二醛(MDA)水平。目前的研究表明,螺旋藻通过增强抗氧化系统、隔离活性氧和抑制细胞损伤,对草甘膦诱导的氧化应激具有保护作用。

Protective role of Spirulina platensis against glyphosate induced toxicity in marine mussel Mytilus galloprovincialis.

Glyphosate is a toxic environmental pollutant that has the ability to induce biochemical and physiological alterations in living organisms. Several studies have focused on the research of protective techniques against the stress induced by this contaminant. In this context, we studied the protective effect of Spirulina against the disturbances induced by glyphosate. A biomarker approach was adopted to determine the impact of glyphosate, Spirulina and their mixture, during two time slots (4 and 7 days), on Mytilus galloprovincialis. Glyphosate treated mussels revealed significantly increased malondialdehyde and decreased acetylcholinesterase (AChE) levels. Spirulina normalized catalase (CAT), glutathione-S-transferase (GST), and AChE activities. Furthermore, it reduced glyphosate-induced malondialdehyde (MDA) levels. The current study suggests a protective effect of Spirulina against glyphosate-induced oxidative stress by strengthening the antioxidant system, sequestering ROS and inhibiting cellular damage.
