“…Similar to our findings, [42] suggested that the disinfection byproducts promoted the evolution of resistant E. coli strains. Similarly, [43] showed that the dose applied for UV disinfection can create a selective environment for antibiotic resistant E. coli to survive better than other serotypes within the population. These findings suggest that better treatment processes are needed to take over old technologies to mitigate antibiotic resistance in the environment.…”

Providing safe water through water reuse is becoming a global necessity. One concern with water reuse is the introduction of unregulated contaminants to the environment that cannot be easily removed by conventional wastewater treatment plants (WWTP). The occurrence of ampicillin, sulfamethoxazole, ciprofloxacin, and tetracycline-resistant Escherichia coli through the treatment stages of a WWTP (raw sewage, post-secondary, post-UV and post-chlorination) was investigated from January to May 2016. The highest concentrations of antibiotic resistant E. coli in the effluent were detected in April after rainfall. Ampicillin-resistant E. coli was the most common at the post UV and chlorination stages comprising 63% of the total E. coli population. The minimum inhibitory concentration (MIC) analysis showed that one in five isolates was resistant to three or more antibiotics, and the majority of these E. coli were resistant to ampicillin, followed by sulfamethoxazole and ciprofloxacin. The highest MIC was detected at the finished water after application of multiple disinfection methods. Tetracycline resistance was the least observed among others, indicating that certain drug families may respond to wastewater treatment differently. Currently, there are no policies to enforce the monitoring of antibiotic-resistant pathogen removal in WWTP. Better guidelines are needed to better regulate reuse water and prevent health risk upon exposure to antibiotic-resistant bacteria.

“…After both types entered the tailing phase there was no difference in inactivation at higher doses of UV. A dose of 20 mJ/cm 2 was used in our study, and similar inactivation rates of the E. coli were observed (Zhang et al, 2017). They attributed the resistance to UV to the production of capsular material by the antimicrobial resistant bacteria.…”

“…Microbial selfaggregation is caused by the change in surface characteristics and the production of extracellular polymers during UV irradiation, and it is thought to cause the tailing effect observed in UV inactivation experiments (Kollu & Örmeci, 2015). Production of capsular material slows the self-aggregation process, which could contribute to the resistant E. coli entering the tailing phase at a higher UV dose (Zhang et al, 2017).…”

“…Biodegradable polymer, as a solid phase denitrification agent could also improve wastewater treatment technology . In ad-dition, ultraviolet (UV) could cause the disinfection of antibiotic-resistant Escherichia coli present in different kinds of wastewaters (Zhang et al 2017). Similarly, vertical and horizontal flow constructed wetlands have been combined to complement each other in order to achieve higher treatment efficiency (Vymazal 2011).…”

Excessive microalgal blooms can be caused by waste disposal into natural water bodies resulting in the destruction of aquatic life. However,, microalgae are also known to efficiently remediate pollutants. After the treatment of wastewater, microalgae absorb specific nutrients and can enhance the production of bioproducts. Growing microalgae as an alternative to wastewater treatment and bioproduct production has received considerable attention due to its rapid growth rate, efficient waste removal, tolerance to stress conditions and ability to accumulate valuable products. In addition, these microorganisms have a high photosynthetic rate of CO2 fixation, oxygen production and need no arable land for their cultivation. Nevertheless, in spite of these theoretical advantages, the issues surrounding the re-use of naturally existing microalgal strains need further exploration in respect to their isolation, identification and lab growth under stress conditions. The true potential of microalgae regarding wastewater treatment and energy has yet to be fully developed. The current cultivation system does not seem to be economically feasible as most of the strains used are commercially purchased. Indigenous microalgae could be the possible answer. Ammonia, one of the major constituents of most wastewaters, contributing to odor, taste, toxicity, and eutrophication is of utmost concern. The present review focuses on the growth of microalgae under high stress of ammonia in wastewater media. It also aims to present a clear-cut methodology for the isolation of microalgae from its indigenous habitat, its growth strategy under different trophic modes of nutrition, nutrient uptake, lipid, and fatty acid production. In addition, some solutions to the problem of how to make microalgae cost-effective and more sustainable are discussed in detail.
