“…On the other hand, Chl b content decreased (by 27%) and Car content increased (by 43%) in Chlamydomonas reinhardtii cells treated with diclofenac (at 134 mg/L) [138]. The exposure to amoxicillin resulted in a ~22% decrease in chlorophyll a and carotenoid content in Microcystis aeruginosa biomass [224]. The content of Chl a in Selenastrum capricornutum cells decreased upon treatment with erythromycin (up to 0.3 mg/L), ciprofloxacin (up to 2.5 mg/L) or sulfamethoxazole (up to 2.5 mg/L), with the biggest drop (by up to ~50%) for erythromycin treatment (at 0.3 mg/L) [80].…”

“…Microalgal cultivation in open systems is subject to changes in temperature and light intensity that can affect the PHRs/PCPs bioremediation process. For instance, the change in light intensity was reported to greatly affect the efficiency of cefradine and amoxicillin removal in Microcystis aeruginosa or Chlorella pyrenoidosa cultures [224]. Moreover, the presence of light can cause photodegradation (photo-oxidation, photolysis) of the structure of PHRs and PCPs, depending on light availability and the presence of inorganic/organic molecules [257,258,259].…”

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.

“…At this moment, the conventional methods including wastewater treatment plants are found ineffective for the complete removal of the recalcitrant antibiotics 444 . Antibiotic residues could influence the biomass and activity of microbial, and induce generations of resistance genes in the environment 445 . At another level, ecotoxicity studies have demonstrated that pharmaceutical pollutants could affect the growth, reproduction and behavior of birds, fishes, invertebrates, plants and bacteria 446 .…”

“…As biodegradation depends on the cellular metabolism of microalgae, antibiotics removal efficiency differs among microalgae species. Chlorella pyrenoidosa and Microcystis aeruginosa abilities to remove cefradine and amoxicillin by biodegradation were analyzed [111]. C. pyrenoidosa was more efficient in the removal of the antibiotics, removing about 42% and 71% of cefradine and amoxicillin, respectively.…”

Antibiotic Resistance in the Drinking Water: Old and New Strategies to Remove Antibiotics, Resistant Bacteria, and Resistance Genes

et al. 2022

Bacterial resistance is a naturally occurring process. However, bacterial antibiotic resistance has emerged as a major public health problem in recent years. The accumulation of antibiotics in the environment, including in wastewaters and drinking water, has contributed to the development of antibiotic resistant bacteria and the dissemination of antibiotic resistance genes (ARGs). Such can be justified by the growing consumption of antibiotics and their inadequate elimination. The conventional water treatments are ineffective in promoting the complete elimination of antibiotics and bacteria, mainly in removing ARGs. Therefore, ARGs can be horizontally transferred to other microorganisms within the aquatic environment, thus promoting the dissemination of antibiotic resistance. In this review, we discuss the efficiency of conventional water treatment processes in removing agents that can spread/stimulate the development of antibiotic resistance and the promising strategies for water remediation, mainly those based on nanotechnology and microalgae. Despite the potential of some of these approaches, the elimination of ARGs remains a challenge that requires further research. Moreover, the development of new processes must avoid the release of new contaminants for the environment, such as the chemicals resulting from nanomaterials synthesis, and consider the utilization of green and eco-friendly alternatives such as biogenic nanomaterials and microalgae-based technologies.
