Changes of metal-induced toxicity by H2O2/NO modulators in Scenedesmus quadricauda (Chlorophyceae)

Original language description

Effect of nitric oxide donor (sodium nitroprusside, SNP, 500 mu M) or hydrogen peroxide scavenger (dithiothreitol, DTT, 500 mu M) on cadmium (Cd) or copper (Cu) uptake (150 mu M solutions) and toxicity using Scenedesmus quadricauda was studied. Combinedtreatments (Cd or Cu + DTT or SNP) usually ameliorated metal-induced toxicity at the level of pigments, proteins, and mineral nutrients in comparison with respective metal alone. Viability tests (MTT and TTC) showed the lowest values preferentially in Cutreatments, indicating higher toxicity in comparison with Cd. Cd showed low impact on amino acids while strong Cu-induced depletion was mitigated by DTT and SNP. Amount of ROS and NO showed the most pronounced responses in SNP variants being rather reciprocal than parallel and regulated ascorbate peroxidase activity. Blot gel analyses of hsp70 protein did not reveal extensive changes after given exposure period. Phenols were elevated by DTT alone while all Cu treatments revealed depleti
