“…It has been established that phototrophic microorganisms are not always able to independently destroy pharmaceutical contaminants in wastewater, especially when mixtures of PCPs are present in them. Some substances are often accumulated by the biomass of phototrophic microorganisms without undergoing transformation under the action of these cells [ 82 ].…”

The review focuses on the appearance of various pharmaceutical pollutants in various water sources, which dictates the need to use various methods for effective purification and biodegradation of the compounds. The use of various biological catalysts (enzymes and cells) is discussed as one of the progressive approaches to solving problems in this area. Antibiotics, hormones, pharmaceuticals containing halogen, nonsteroidal anti-inflammatory drugs, analgesics and antiepileptic drugs are among the substrates for the biocatalysts in water purification processes that can be carried out. The use of enzymes in soluble and immobilized forms as effective biocatalysts for the biodegradation of various pharmaceutical compounds (PCPs) has been analyzed. Various living cells (bacteria, fungi, microalgae) taken as separate cultures or components of natural or artificial consortia can be involved in biocatalytic processes under aerobic or anaerobic conditions. Cells as biocatalysts introduced into water treatment systems in suspended or immobilized form are used for deep biodegradation of PCPs. The potential of combinations of biocatalysts with physical–chemical methods of wastewater treatment is evaluated in relation to the effective removing of PCPs. The review analyzes recent results and the main current trends in the development of biocatalytic approaches to biodegradation of PCPs, the pros and cons of the processes and the biocatalysts used.

“…Red algae Gelidiella acerosa are able to remove 96.36% copper at pH 5.31 with the initial concentration of 23.87 mg/L (Dulla et al 2020), whereas Chlorella vulgaris, 88% (Ansilago et al 2021). There are few publications concerning biosorption with the use of Raphidocelis subcapitata, and the ones that exist do not refer to heavy metals (Carvalho et al 2015, Hom-Díaz et al 2022, so their ability to remove metal ions, optimum pH conditions or potential substances that could facilitate the process are not yet well known. This microorganism is used most often in toxicity tests.…”

The aim of the research was to evaluate the effectiveness of the removal of Cu and Pb ions by algae. The experiments were carried out in the presence of two algal populations: a pure culture of Raphidocelis subcapitata, and a mixed chlorophyta population. The research involved a model study, experiments in the presence of wastewater from the manufacture of batteries, and the study of process kinetics. The wastewater pH was 4.0, and the initial concentrations of metal ions in the wastewater were 95.4 mg/L for Pb and 48.3 mg/L for Cu, respectively. The maximum sorption capacity of the pure Raphidocelis subcapitata culture was 14.8 mg/g d.m. for Pb, corresponding to the removal of 72% of lead, and 6.1 mg/g d.m. for Cu, corresponding to the removal of 43% of copper from the wastewater. The best ion sorption efficiency in the case of the mixed chlorophyta population was 7.0 mg/g d.m. for Pb, i.e., 61% removal of lead, and 12.8 mg/g d.m. for Cu, i.e., 69% removal of copper ions from the wastewater. The optimum duration of the process was found to be 1 hour, since the majority of biomass samples reached the maximum saturation after that time. On the basis of the obtained results (Lagergren models), it was found that the dominant mechanism of the process was chemisorption.

The widespread problem of water pollution is jeopardizing the ecosystem and our health. The contamination of freshwater through anthropogenic activities and its discharge into the ecosystems leads to the generation of wastewater. Wastewater mainly contains nutrient loads and the recent emerging contaminants such as pharmaceutical wastes, drugs, micropollutants, heavy metals, pesticides, phenolic compounds, and dyes have increased and contaminated the aquatic bodies. The existence of these emerging pollutants can cause serious threats to ecosystems and humans. Thus, conventional wastewater treatment was focused on the removal of solid compounds or nutrient loads. However, it could not remove the emerging contaminants and later microalgae that are photosynthetic eukaryotic microorganisms were found to be an efficient and eco‐friendly source for the remediation of diverse kinds of wastewater. Apart from nutrient removal, the algal biomass acts as the efficient feedstock for the generation of bioenergy products. However, limited data have been published regarding the remediation of emerging pollutants through microalgae. Thus, focusing on the recent gaps, the current review provides an overview of the potential of microalgae for the remediation of nutrient loads. Critically deliberate the recent advances and detailed summary of microalgae potential for the remediation of wastewaters containing high nutrient loads especially focused on the remediation of different emerging contaminants. It highlights the advanced approaches used in the microalgae remediation process and provides comprehensive information about the different bioenergy products such as liquid, gaseous, and bioelectricity generated through the utilization of wastewater‐grown microalgae.
