“…The negligible difference of microalgal growth and SGR influenced by doxylamine indicated that S. obliquus is a tolerant species toward the treatment of doxylamine-polluted wastewater. Earlier studies also demonstrated low concentrations of levofloxacin, amoxicillin, and ciprofloxacin (Xiong et al, 2017;Xie et al, 2020). For example, the growth of a green microalga, Chlorella vulgaris, was not influenced with exposure up to 5 mg L −1 levofloxacin (Xiong et al, 2017).…”

“…For example, the growth of a green microalga, Chlorella vulgaris, was not influenced with exposure up to 5 mg L −1 levofloxacin (Xiong et al, 2017). Xie et al (2020) investigate the effect of ciprofloxacin on a Chlamydomonas sp., which showed that there was no significant alteration of microalgal growth under 10 mg L −1 ciprofloxacin. Liu et al (2016) demonstrated that there was a hermetic effect of amoxicillin on the growth of a cyanobacteria, Microcystis aeruginosa.…”

Pharmaceutical contaminants (PCs) have been recognized as emerging contaminants causing unexpected consequences to environment and humans. There is an urgent need for development of efficient technologies to treat these PCs from water. The current study has investigated the removal capacity of a green microalgal species, Scenedesmus obliquus, for doxylamine, chemical oxygen demand (COD), and nutrients from real wastewater. Results have indicated that S. obliquus can grow well in the doxylaminepolluted wastewater with the achievement of 56, 78.5, 100, and 89% removal of doxylamine, COD, total nitrogen (TN), and total phosphorus (TP). Addition of 2 g L −1 bicarbonate enhanced the removal of doxylamine up to 63% and slightly inhibited the removal of COD. Decreased carbohydrate (28-26%) and increased protein content (30-33%) of the harvested biomass have been observed after cultivation in the wastewater. The current study has shown the feasibility of using microalgae-based biotechnologies for PC-contaminated wastewater.

“…Biodegradation-based TPs were identified by using UPLC-QToF-MS/MS in high resolution-mass spectrometry (HRMS) with positive ESI mode. To explore the environmental implications of the produced TPs, their persistence (P), bioaccumulation (B), and ecotoxicity (T) were assayed by EPI Suite TM software (version 4.11) and ECOSAR class program developed by United States Environmental Protection Agency (US-EPA) ( Xie et al, 2020 ). The description of removal mechanisms for OT, HPLC operating conditions, TPs identification by UPLC-QToF-MS, and PBT parameters are provided in Section S4 and Fig.…”

Increased worldwide consumption of antiviral drugs (AVDs) amid COVID-19 has induced enormous burdens to the existing wastewater treatment systems. Microalgae-based bioremediation is a competitive alternative technology due to its simultaneous nutrient recovery and sustainable biomass production. However, knowledge about the fate, distribution, and interaction of AVDs with microalgae is yet to be determined. In this study, a concentration-determined influence of AVD oseltamivir (OT) was observed on the biochemical pathway of Chlorella sorkiniana (C.S-N1) in synthetic municipal wastewater. The results showed that high OT concentration inhibited the biomass growth through increased oxidative stress, and restrained photosynthesis. Nevertheless, complete OT removal was achieved at its optimized concentration of 10 mg/L by various biotic (82%) and abiotic processes (18.0%). The chemical alterations in three subtypes of extracellular polymeric substances (EPS) were primarily investigated by electrostatic (OT +8.22 mV vs. C.S-N1 -18.31 mV) and hydrophobic interactions between EPS-OT complexes supported by secondary structure protein analysis. Besides, six biodegradation-catalyzed transformation products were identified by quadrupole-time-of-flight mass spectrometer and by density functional theory. Moreover, all the TPs exhibited log Kow ≤ 5 and bioconcentration factor values of < 5000 L/kg, meeting the practical demands of environmental sustainability. This study broadens our understanding of microalgal bioadsorption and biodegradation, promoting microalgae bioremediation for nutrient recovery and AVDs removal.

BACKGROUND High‐efficiency saccharification technology is one of the bottlenecks of cellulosic bio‐hydrogen production. Cellulosic feedstocks saccharification currently performed by commercial cellulase, which is composed of different fungal cellulase. Compared with fungi, thermocellulosic bacteria represented by Ruminiclostridium thermocellum have a complete cellulase system, and a higher cellulase catalytic efficiency than fungi; however, R. thermocellum is susceptible to feedback inhibition by cellobiose, which limits the application of R. thermocellum on cellulosic bio‐hydrogen production. In this study, a strain named R. thermocellum M3, which is not subject to feedback inhibition by cellobiose, was used in the bio‐hydrogen production of cellulosic agricultural waste feedstocks to explore the feasibility of bacterial saccharification of cellulosic substrates for biological hydrogen production. RESULTS Results of batch tests indicate that the combination of domestic sewage sludge and strain M3 promoted the hydrogen production for different lignin content feedstocks (rice straw: from 0.66 to 6.42 mmol H2/g substrate; corn cob: from 0.61 to 5.55 mmol H2/g substrate; pine wood waste: from 0.58 to 5.32 mmol H2/g substrate), which were competitive with the combination of domestic sewage sludge and Trichoderma viride cellulase. Specific activity analysis indicates that compared with the addition of T. viride cellulase, the addition of strain M3 completed the cellulase system in sludge. CONCLUSION Thermo‐anaerobic bacteria R. thermocellum M3 enhanced the hydrogen production of the consolidated bioprocessing (CBP) of raw lignocellulosic agricultural wastes and, more importantly, provided a promising solution for the CBP strategy in the industrial application of lignocellulose bioconversion. © 2021 Society of Chemical Industry
