This study investigated the growth, apoptosis and oxidative stress of the cyanobacterium Microcystis viridis exposed to glyphosate. Results showed that growth parameters, namely, cell destiny, chlorophyll a content, and protein content, were affected by glyphosate. The viability of the treated cells was monitored to further investigate the toxicity of glyphosate on M. viridis. After 24 and 48 h of exposure, glyphosate enhanced superoxide dismutase (SOD) activity and decreased malondialdehyde (MDA) concentration. The decrease in the MDA concentration might be caused by the enhanced SOD activity. This study helped elucidate the toxic effects of glyphosate on cyanobacteria and contributed to environmental assessment and protection.
本研究调查了受草甘膦影响的绿藻（Microcystis viridis）的生长、凋亡和氧化应激。结果表明，生长参数（即细胞命运、叶绿素 a 含量和蛋白质含量）受到草甘膦的影响。通过监测处理细胞的活力，进一步研究了草甘膦对 M. viridis 的毒性。暴露于草甘膦 24 和 48 小时后，超氧化物歧化酶（SOD）活性增强，丙二醛（MDA）浓度降低。MDA 浓度的降低可能是由于 SOD 活性的增强。本研究有助于阐明草甘膦对蓝藻的毒性作用，并为环境评估和保护做出了贡献。
