“…The amount of protein in the tissue or cells depends on the kinetic balance of its catabolism. The decrease in protein content may be due to proteolysis increase to compensate lost energy of cells or the organization of lipoproteins for mending cells (Liu et al 2018). Pre-treatment has a stimulatory effect on protein formation due to its short course.…”

In response to highly severe environmental conditions, the accumulation of vast levels of astaxanthin by Haematococcus Pluvialis is a recorded event. However, there is little investigation into the nature and possible interactions of the poisonous chemical factors on this pigment's synthesis. In this study, H. pluvialis was exposed to the environment phenol to determine cellular responses, synthesis of pigments, and astaxanthin. The phenol influences in different concentrations (0, 50, 100, and 150 mg l-1) were checked out by two ways; a treatment (14 days) and pre-treatment (7 days + 7 days) done on green and red stages of H. pluvialis. The amount of carotenoid, protein, and dry weight increased, but the amount of carbohydrates and chlorophyll reduced in treated green cells with a phenol. The pre-treatment increased the amount of chlorophyll a, carbohydrates, and carotenoids in green cells, but it did not significantly affect the dry weight, protein of green cells, and the amount of protein in red cells. The phenol treatment also enhanced the carotenoid, carbohydrate, dry weight, and protein of red cells. In general, the treatment and pre-treatment of phenol in the green phase and low concentrations significantly affected the alga. However, the pre-treatment had a more considerable effect on red cells in high concentrations. While the treatment in the high concentrations had notable effects on the xanthophylls, pre-treatment had the same effects on the xanthophylls at low concentrations. These results show that H. pluvialis can adapt to toxic environments due to the xanthophylls.

“…Photosynthetic pigment is a basic parameter for evaluating photosynthetic activity which is often used as an indicator of plant damage under adversity stress (Liu and Wu, 2018). Many studies have shown that tetracyclines can signi cantly reduce chlorophyll contents (Rydzyński et al, 2019;Siedlewicz et al, 2020b).…”

“…The antioxidant system composed of antioxidant enzymes and antioxidants in the body can remove free radicals produced by cell growth and metabolism under normal circumstances (Zhou et al, 2018). However, when an organism is stimulated by the outside, there will be excessive production of ROS, such as superoxide radicals, hydroxyl radicals and H 2 O 2 (Wu et al, 2010 (Kouka et al, 2018;Liu and Wu, 2018). After 7 D of CTC/ OTC exposure, no signi cant differences were found for the POD and PPO activities, but the CAT activity of V. natans decreased signi cantly under high concentrations of CTC/ CTC (≥ 30 mg/L).…”

Tetracyclines are frequently detected in water bodies due to their widespread use in aquaculture and animal husbandry. A hydroponic experiment was conducted to explore the phytotoxic effects of Vallisneria natans (Lour.) Hare exposed to various concentrations of chlortetracycline (CTC) and oxytetracycline (OTC) (0, 0.1, 1, 10, 30, 50 and 100 mg/L) for 7 days (7 D) and 14 days (14 D), respectively. The results showed that similar to OTC treatment for 7 D, the relative growth rates (RGR) and catalase (CAT) activity of V. natans , after 7 D of CTC exposure, decreased signi cantly at 10 mg/L and 30 mg/L, respectively. The content of soluble protein notably decreased when CTC ≥ 10mg/L and OTC ≥ 30mg/L. The hydrogen peroxide (H 2 O 2 ) content was signi cantly stimulated when OTC ≥ 10mg/L, while it hardly changed when exposed to CTC. After 14 D, the malondialdehyde (MDA) and H 2 O 2 contents of V. natans were signi cantly higher than those of the control group under high concentration of OTC (≥ 30mg/L), but they didn't change signi cantly under high concentration of CTC. The activity of polyphenol oxidase (PPO), under CTC treatment after 14 D, showed rst a signi cant increase then decrease, the maximum value (125% of the control) was notice at 10 mg/L CTC, while it remained unchanged when exposed to OTC. The soluble protein content signi cantly decreased at 10 mg/L CTC and 0.1 mg/L OTC, respectively. The RGR, CAT and peroxidase (POD) activities, similar to OTC treatment after 14 D, decreased evidently when CTC was 10 mg/L, 30 mg/L and 0.1 mg/L, respectively. CTC and OTC harm the chlorophyll content of V. natans after 14 D, and the reduction of chlorophyll a and carotenoid were more pronounced than chlorophyll b. The results suggest that CTC and OTC both have negative effect on the growth of V. natans , and OTC can cause oxidative damage in V. natans but CTC harm the metabolism process without inducing oxidative damage. Overall, the toxicity of OTC to V. natans is stronger than that of CTC.

“…However, when an organism is stimulated by the outside, there will be excessive production of ROS, such as superoxide radicals, hydroxyl radicals and H 2 O 2 (Wu et al, 2010). The enzyme CAT oxidizes H 2 O 2 to generate H 2 O and O 2 , POD catalyzes the decomposition of H 2 O 2 through the oxidation of phenolic compounds and PPO can reduce the toxicity of phenol to plants through hydroxylation and oxidation of exogenous phenols (Kouka et al, 2018;Liu and Wu, 2018). After 7 D of CTC/ OTC exposure, no signi cant differences were found for the POD and PPO activities, but the CAT activity of V. natans decreased signi cantly under high concentrations of CTC/ CTC (≥ 30 mg/L).…”
