“…The effect on protein content was revealed after exposure of aquatic species from different trophic levels to metal copper (Pytharopoulou et al, 2013), to Metolachlor (Martins et al, 2011), to triazine herbicides (El-Sheekh et al, 1994) and to the combination of the metal copper and chloroacetanilide herbicide applied to phytoplankton species (Lu et al, 2015). The latter is in agreement with our result that the metal-herbicide mixture significantly predicted protein content of the diatom species.…”

Pesticides and metals are often used in agriculture and are therefore often simultaneously discharged to nearby estuarine and marine areas. The effects of this organic-inorganic chemical mixture on food quality of aquatic organisms are currently unknown. In this study we test if a mixture of copper (inorganic) and the herbicide Primextra® Gold TZ (organic) affects the quality of the diatom Thalassiosira weissflogii and the copepod Acartia tonsa - two key species that fuel the local food-web. We quantified quality (i.e. energy content as food for the next trophic level) in terms of fatty acids, proteins and thiobarbituric acid reacting substances. We found non-additive effects (positive and negative) of the metal-herbicide mixture on the diatom and copepod species. In general, nutritionally important biochemical parameters of Acartia tonsa were most sensitive to the chemical stressors.

For the cyanobacterium Microcystis aeruginosa , CTC within the range of 1–10 mg/L slightly (up to ~10%) inhibited Microcystis growth [60], caused 50% toxicity at 15.2 mg/L (29.5 µmol/L) [64], and completely inhibited Microcystis growth at 20 mg/L [60]. However, CTC at 0.05 mg/L was also reported to cause 50% growth inhibition to Microcystis aeruginosa [56].…”

“…Lipid peroxidation occurs during cellular oxidative stress, leading to the generation of malondialdehyde (MDA), a peroxidation product of fatty acids. Table 12 shows that PHRs such as amoxicillin [219,220,221], ciprofloxacin [108,222], enrofloxacin [95,97], norfloxacin [99,219], levofloxacin [102], tetracycline [57], doxycycline [71], chlortetracycline [64], florfenicol [46], thiamphenicol [46], erythromycin [113,222], spiramycin [220], sulfamethoxazole [222], carbamazepine [170] and ethinylestradiol [179] and PCPs such as triclosan [194,195] can cause increases in MDA content in different microalgal strains. The general pattern in mentioned reports is that MDA content increases up to the maximal concentration with the increase in PHRs/PCPs concentrations in the media.…”

In this review, the effect of pharmaceuticals (PHRs) and personal care products (PCPs) on microalgal growth and metabolism is reported. Concentrations of various PHRs and PCPs that cause inhibition and toxicity to growths of different microalgal strains are summarized and compared. The effect of PHRs and PCPs on microalgal metabolism (oxidative stress, enzyme activity, pigments, proteins, lipids, carbohydrates, toxins), as well as on the cellular morphology, is discussed. Literature data concerning the removal of PHRs and PCPs from wastewaters by living microalgal cultures, with the emphasis on microalgal growth, are gathered and discussed. The potential of simultaneously bioremediating PHRs/PCPs-containing wastewaters and cultivating microalgae for biomass production in a single process is considered. In the light of reviewed data, the feasibility of post-bioremediation microalgal biomass is discussed in terms of its contamination, biosafety and further usage for production of value-added biomolecules (pigments, lipids, proteins) and biomass as a whole.

“…It was found that SOD and CAT activities in Chlorella vulgaris increased markedly under the stress of the antibiotic streptomycin, which could effectively remove ROS and reduce membrane damage [19]. It was also reported that SOD and CAT activities in Chlorella pyrenoidosa substantially increased to be against to the stress of ceftazidime and chlortetracycline [27,28]. In the present study, the activities of SOD and CAT reached the maximum at 48 h and decreased at 96 h under the OFL stress, but they still significantly higher than the initial enzyme activities ( p < 0.05).…”

“…It was reported that the activities of SOD and CAT enzymes increased in Chlorella vulgaris when exposed to streptomycin [19]. It was also found that the SOD and CAT activity in green algae substantially increased against the stress of sulfamethoxazole, erythromycin, clarithromycin, ciprofloxacin, cefradine, ceftazidime, and chlortetracycline [27,28,29]. Biofilms was considered to be less sensitive to antibiotics than their equivalent planktonic form due to EPS being able to reduce and even sequester antibiotics into the biofilm inside [30,31].…”

Antibiotic residues have been detected in aquatic environments worldwide. Biofilms are one of the most successful life forms, and as a result are ubiquitous in natural waters. However, the response mechanism of freshwater biofilms to the stress of various antibiotic residues is still unclear. Here, the stress of veterinary antibiotic florfenicol (FF) and fluoroquinolone antibiotic ofloxacin (OFL) on freshwater biofilms were investigated by determining the changes in the key physicochemical and biological properties of the biofilms. The results showed that the chlorophyll a content in biofilms firstly decreased to 46–71% and then recovered to original content under the stress of FF and OFL with high, mid, and low concentrations. Meanwhile, the activities of antioxidant enzymes, including superoxide dismutase and catalase, increased between 1.3–6.7 times their initial values. FF was more toxic to the biofilms than OFL. The distribution coefficients of FF and OFL binding in extracellular polymeric substances (EPS)-free biofilms were 3.2 and 6.5 times higher than those in intact biofilms, respectively. It indicated that EPS could inhibit the FF and OFL accumulation in biofilm cells. The present study shows that the EPS matrix, as the house of freshwater biofilms, is the primary barrier that resists the stress from antibiotic residues.
