The effect of cadmium on the growth and antioxidant response for freshwater algae Chlorella vulgaris

Abstract: The objective of the present work was to evaluate the effect of exogenously applied cadmium on the physiological response of green algae Chlorella vulgaris. The study investigated the long-term effect (18 days) of cadmium on the levels of algae biomass, assimilation pigment composition, soluble protein, oxidative status (production of hydrogen peroxide and superoxide anion), antioxidant enzymes (such as superoxide dismutase, peroxidase, catalase and glutathione reductase enzyme) in C. vulgaris. The results sho… Show more

“…Reduction of CAT activity (T5) at higher content of HMs might be attributed to the inactivation of an enzyme by ROS, decrease in enzyme synthesis, or change in the assembly of its subunits. Biochar improved CAT activity by 38.79% in Chlorella vulgaris 2 .…”

“…To figure out the role of applied amendments in attenuation of metal-induced oxidative injury to plants, the activities of some key antioxidant enzymes such as CAT, PAL and PPO were measured (Figure 4). CAT is a ubiquitous metalloenzyme which is involved in lessening the ROS level by quenching redundant H 2 O 2 [77,78] and this tetramericheme-containing enzyme has been widely used as a potential bioindicator for metal phytotoxicity [79][80][81]. As revealed by Figure 4a, compared to both CK1 and CK2, CAT activity augmented in all amendment treatments by varying degrees and irrespective of the amendments' application rates.…”

“…A previous study (Cheng et al. ) reported decreased chlorophyll and carotenoid contents following long‐term (after 18 d) Cd(II) exposure at concentrations greater than 3 mg · L −1 in C. vulgaris . However, doses up to 1 mg · L −1 Cd(II) had a positive effect; therefore, the effect always depends on the dose and kind of microalgae.…”

A previous study (Cheng et al 2016) reported decreased chlorophyll and carotenoid contents following long-term (after 18 d) Cd(II) exposure at concentrations greater than 3 mg Á L À1 in C. vulgaris. However, doses up to 1 mg Á L À1 Cd(II) had a and Scenedesmus quadricauda cultivated for 120 h in TAP medium containing 10 lM 5azacytidine (5-aza), 40 lM CdCl 2 Á 5H 2 O (Cd) or a combination of 10 lM 5-aza and 40 lM Cd .…”
