Sulfadiazine (SD), sulfamerazine (SM1), and sulfamethazine (SM2) are widely used and disorderly discharged into surface water, causing contamination of lakes and rivers. However, microalgae are regard as a potential resource to alleviate and degrade antibiotic pollution. the physiological changes of Chlorella vulgaris in the presence of three sulfonamides (SAs) with varying numbers of-cH 3 groups and its SA-removal efficiency were investigated following a 7-day exposure experiment. Our results showed that the growth inhibitory effect of SD (7.9-22.6%), SM1 (7.2-45.9%), and SM2 (10.3-44%) resulted in increased proteins and decreased soluble sugars. oxidative stress caused an increase in superoxide dismutase and glutathione reductase levels but decreased catalase level. the antioxidant responses were insufficient to cope-up with reactive oxygen species (hydrogen peroxide and superoxide anion) levels and prevent oxidative damage (malondialdehyde level). the ultrastructure and DnA of SAtreated algal cells were affected, as evident from the considerable changes in the cell wall, chloroplast, and mitochondrion, and DnA migration. C. vulgaris-mediated was able to remove up to 29% of SD, 16% of SM1, and 15% of SM2. Our results suggest that certain concentrations of specific antibiotics may induce algal growth, and algal-mediated biodegradation process can accelerate the removal of antibiotic contamination. The increase in the use of antibiotics in human and veterinary medicine has raised concerns about their environmental accumulation 1. The accumulation of sulfonamides (SAs), the antibacterial agents that inhibit dihydrofolic acid synthesis, is of particular interest 2. Although the recorded environmental levels of SAs are usually within the microgram per litre range, this concentration may increase bacterial resistance and magnify toxicity via bioaccumulation in food chains 3. Considering the non-degradability of SAs, modern sewage treatment plants may be insufficient to completely remove these agents 4 , resulting in their continuous presence in aquatic environment 5. Thus, there is an urgent need to develop effective methods for SA-removal. Freshwater algae form the most abundant biomass source in aquatic environments and are known to survive under extremely hostile environments 6,7. Several studies have reported the ability of algae to effectively remove persistent organic pollutants such as pesticides 8 , phenols 9,10 , and estrogen 11,12 , and algae can uptake organic pollutants as carbon sources for their growth 7. Thus, algae are considered as a potential resource to alleviate and

“…Moreover, antibiotics modulated (increased or decreased) the xanthophyll cycle pool size and xanthophyll cycle conversion state in Pseudokirchneriella subcapitata [222]. Streptomycin interfered with the synthesis of proteins involved in the photosynthetic mechanism in Chlorella vulgaris cells [73]. Antibiotics were reported to completely inhibit protein synthesis in cyanobacteria [274], blocked the induction of the expression of desaturases ( des ) in Synechocystis [275] and the synthesis of phycoerythrin in Fremyella diplosiphon [276] and phycocyanin in Anacystis nidulans [232].…”

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.

“…The φPo values were altered as a result of the in vitro conditions. The efficiency by which light is absorbed by the antenna, trapped by the RC, and used to reduce to Q A − is affected by the treatment condition (Perales-Vela et al 2016). High sucrose concentrations added during in vitro growth may cause a decline in φPo due to downregulation of photosynthesis, as the high sucrose content causes a low sink demand in the plants (Matysiak and Gabryszewska 2016).…”

In vitro culture conditions have a major impact on the physiology and anatomy of micropropagated plants. Sucrose plays a very important role in micropropagation protocols, and is frequently employed during in vitro culture. However, it may induce disorders that negatively interfere with plant growth and development, such as a low photosynthetic rates. The aim of this study was to analyze the impacts of in vitro conditions on the anatomy and photosynthetic performance of Aechmea blanchetiana (Baker) L.B. Sm. Plants previously grown in vitro were transferred to culture media containing 0, 15, 30, or 45 g L −1 sucrose. Two different culture container sealing systems were tested: lids with a filter (permitted gas exchange), and with a PVC-covered filter (blocking fluent gas exchange). Plants grown with exogenous sucrose displayed anatomical traits that could decrease mineral and carbohydrate uptake from the medium. Plants cultured under photoautotrophic conditions had a thinner exodermis and the highest number of metaxylem vessels in the roots. This positively impacted the plant growth and physiological status. Sucrose induced plants with photosystem II (PS II) disorders, such as a lower number of active reaction centers. Under photoautotrophic conditions, there was an increase in absorbed energy flux per cross section (ABS/CSm), and energy transport flux (ETo/CSm), followed by a decrease in the energy dissipation flux (DIo/CSm). This indicated a high PS II efficiency, according to the performance index (PI (ABS) ). The use of sucrose can induce physiological disorders in A. blanchetiana plants during in vitro propagation. Photoautotrophic conditions induce plants without anatomical disorders, and positively influence PS II efficiency.
